Project Case Study Proton Therapy Cancer Treatment Controlled using NI Single-Board RIO Apr 1, 2024 89e44ffe-6791-43ca-abd4-a8175b558952 89e44ffe-6791-43ca-abd4-a8175b558952 Home > Case Studies > *As Featured on NI.com Original Authors: Jacob McCulley, ProNova Solutions Edited by Cyth Systems ProNova SC360 Proton Therapy System The Challenge Developing a highly accurate and precise proton beam control solution to deliver a prescribed radiological dose to a specific location within a tumor. The Solution Implementing intensity-modulated pencil beam scanning in the ProNova SC360 by using Single-Board RIO solutions to meet the monitoring and control requirements to safely and effectively deliver the radiological dose to treat a tumor. About ProNova More than 1.6 million people will be diagnosed with cancer this year in the United States, with 320,000 of those cases eligible for proton therapy. However, with just 24 existing proton therapy centers, only 5 percent of eligible patients can receive this treatment. ProNova aims to make proton therapy a widely available cancer treatment option by delivering a lower-cost, more compact, and more energy-efficient proton therapy system without sacrificing clinical capabilities. About the SC360 We designed the SC360 proton therapy system to provide the flexibility required to support 1 to 5 treatment rooms, allow for different treatment room configurations, meet individual customer needs, and enable easy integration with future R&D projects. This modular approach lends itself nicely to the design of a distributed control system with NI reconfigurable I/O (RIO) technology. This technology, in conjunction with the LabVIEW Real-Time Module and the LabVIEW FPGA Module, provide the hardware flexibility and programming capabilities needed to rapidly develop advanced embedded monitoring and control solutions for the SC360 without sacrificing the performance requirements of a proton therapy system. Consequently, we used CompactRIO and Single-Board RIO solutions extensively throughout the SC360 for magnet control, vacuum control, beamline diagnostics, and dose delivery. The SC360 offers a highly accurate and precise method for targeting tumors by using intensity modulated proton therapy (IMPT) with pencil beam scanning (PBS). This technology helps doctors treat large, non-contiguous targets with improved local control; thus, sparing sensitive organs and normal tissue from unnecessary radiation exposure. This allows proton therapy to provide a dosimetric advantage in more than 80 percent of all external beam radiation treatment cases. Left: Simplified diagram of dose delivery system, Right: Dose Delivered to a Target Along Z-Axis (left) and XY-Axis (right). SC360 Dose Delivery System The Dose Delivery System, or DDS, is the SC360 subsystem that accurately and precisely delivers protons from the beamline to a specific target in the patient. We implemented IMPT with PBS in the DDS using three sbRIO-9626 embedded controllers. The individual controller responsibilities include: · dose monitoring · beam control · beam position monitoring (Figure 2). A PBS treatment plan contains a set of locations, or spots, in 3D space (horizontal-X, vertical-Y, depth-Z) that are each prescribed a specific radiological dose. The spot produced by the proton beam is between 4–8 mm depending on depth and must be delivered within 1 mm of the prescribed location. Modulating the intensity of the proton beam adds a time dimension to the treatment plan by controlling the beam current to deliver each spot in ~5 ms. We used the Single-Board RIO FPGA and LabVIEW FPGA Module for each of these applications to meet the timing requirements for spot delivery and the response times required to safely remove the beam from the treatment room during spot transitions or following a safety interlock. Additionally, hard-wired signals pass between the FPGAs of each of the control components to trigger spot completion, spot advancement, and treatment faults. Each DDS module uses LabVIEW Real-Time to receive treatment plans, process spot treatment results, and report treatment results back to the treatment room master control component. Beam Control We control the vertical and horizontal position of the proton beam from the beamline to the patient using specialized scanning magnets. The Single-Board RIO device dedicated to beam control is responsible for controlling the magnetic fields required to deflect the proton beam to the desired spot location. Additionally, this controller provides the beam intensity set point required to maintain spot durations of 5 ms. We can sample the analog I/O available on the sbRIO-9626 at 10 kHz to continuously monitor critical feedback signals (control signals, load voltages, currents, fields, temperatures, and water flow) related to vertical, horizontal, and intensity control. The beam control system safely removes the proton beam from the treatment room if any of the monitored signals fall outside set point tolerances. The beam control module is triggered to adjust the magnet fields for the next spot when the dose has been delivered for the current spot. Upon verification that the monitored signals have settled at the new set point, the treatment can continue. We can complete and verify this spot transition process in <800 µs. Dose Monitoring We monitor the amount of charge collected on two redundant dose planes located between the output of the beamline and the patient to control the dose delivered to a spot. We used the sbRIO-9626 to meet the analog I/O and digital I/O requirements for sampling the dose plane signal conditioning circuits. Additionally, we use the onboard FPGA to monitor the delivered dose at frequencies up to 1 MHz, and provide the response time required to safely remove the proton beam from the treatment room upon fulfilling the prescribed dose or in the event the delivered dose falls outside of treatment tolerances. This level of precise control makes it possible to deliver a radiological dose within 1 percent of the prescribed dose. The dose monitoring module also synchronizes spot advancement with other DDS modules upon the delivery of a prescribed dose. We accomplish this by 1) removing the beam from the room when the prescribed amount of dose is delivered, 2) triggering the beam control and beam position monitoring modules once the spot has been completed, 3) receiving notification from the beam control and beam positioning monitoring modules upon successful spot transition, and 4) completing the spot by verifying the delivered dose is within treatment tolerances. Once the spot transition has completed (<1 µs), the treatment plan resumes on the next spot if all components are confirmed ready for safe beam delivery. This process incrementally advances the control components through a treatment plan until a dose has been delivered to all prescribed spots. What’s Next? ProNova received FDA approval for the SC360 earlier this year (2020) and plans to start treating the first patients later this year at the Provision Center for Proton Therapy in Knoxville, Tennessee. We have planned future SC360 installations for cities across the United States, Europe, and Asia. ProNova strives to improve upon the clinical advantages of proton therapy and introduce advanced technologies that help make this treatment option a reality for more cancer patients.

Project Case Study Continental Automotive Reduces the Cost of Automotive Sensor Test Systems Mar 26, 2024 dc5c52cb-2df9-462d-915e-ef3a6417ad75 dc5c52cb-2df9-462d-915e-ef3a6417ad75 Home > Case Studies > *As Featured on NI.com Original Authors: Ing. Alejandro Sarabia, Continental Automotive Edited by Cyth Systems Automotive Sensor Test Systems The Challenge Designing and developing an automated test system for automotive sensors that is easy to maintain and minimizes hardware costs. The Solution Using NI LabVIEW system design software and PXI modular instrumentation to build a custom end-of-line test system in a short time that has the capacity to increase the number of products that can be simultaneously tested. The reliability of variable reluctance (VR) speed sensors is critical. These sensors must be able to operate in the hardest conditions and be highly compatible with all parts of the system. They need to be resistant to external factors such as temperature, humidity, dirt, and some chemicals. Additionally, the sensors must give reliable information without the results being affected by electromagnetic fields and the vicinity of other sensors. Left: The system was replicated to create two parallel testing environments. Right: The graphical user interface shows the values for resistance, inductance, and voltage, as well as the pass/fail values. Application Description For this project, we needed to design a complete test system for all the different electrical and mechanical aspects, ranging from the creation of the feeler gauge to the programming of the software that verifies the different speed sensors. The system carries out the following two main tests on the VR sensor: Measurement of the nominal resistance and inductance of the coil, including checking that the values for the resistance and the inductance of the sensor’s coil are within normal working parameters. Measurement of the induced voltage. We can use the NI PXI-6515 module to control the servomotor of a cogwheel that simulates a tire rotation. The rotation excites the sensor’s coil to generate a voltage signal. We can use the NI PXI-4072 digital multimeter (DMM) and the NI LabVIEW Advanced Signal Processing Toolkit to measure and analyze the signal to obtain its shape, amplitude, and phase angle. We can also use a signal from the servomotor to transmit the data from the DMM and to measure the induced voltage, always on the same wheel cogs. We used this measurement method for each VR sensor, otherwise, we would have different voltage measurements for each pin and the potential cost of the R&R analysis would increase by 100 percent. One of the benefits of using the NI PXI-4072 DMM together with the NI PXI-2503 digital I/O module was that we could carry out multiple measurements such as resistance, inductance, and voltage using a single instrument. This provided significant cost savings. Also, using the NI PXI-6515 digital I/O card meant we could directly control the servomotor and the feeling gauge’s rotation without the need for additional hardware, which resulted in additional savings over using a programmable logic controller just for this task. Finally, implementing the tester in the PXI industrial platform led to a small and modular system. Therefore, we could fit all the testing equipment for the digital signals, analog measurements, and commutation, as well as the equipment for processing and mathematical analysis, in a small rack, which reduced the size of the testing cabinet.

When these facilities experience unexpected failures or transient events, it can impact entire regional power networks, and potentially cause widespread blackouts that affect the essential infrastructure communities depend on. Disturbances to the excitation system, even on a microsecond-level, can trigger catastrophic equipment failures and grid instabilities that could cost utilities providers millions in lost revenue and emergency repairs. In modern power plants, the main sources of electrical energy come from synchronous generators. This type of generator is an AC electrical machine that rotates at a constant speed synchronously with grid frequency. It uses an excitation system to control the strength of the magnetic field through its rotor windings, thereby regulating voltage output and reactive power. Understanding and monitoring the transient behavior of these systems is crucial for maintaining grid stability and preventing equipment failures. Asset Health Monitoring The Nikola Tesla Institute of Electrical Engineering, an applied research institute that designs and manufactures complete excitation systems for synchronous generators, took on the challenge of designing and implementing a solution to monitor the behaviors of excitation and generator systems during normal operation and failures. They recognized the need for a data acquisition solution completely independent of the control signals of the excitation system to enable experimentation without risking the health of primary equipment or interfering with normal plant processes. Instantaneous Data Visualization The research engineers decided to built their monitoring solution with NI CompactDAQ (cDAQ) hardware and LabVIEW software. A few of the key system hardware components were: NI cDAQ-9172 chassis with NI 9203 analog input modules and NI 9245 digital input modules Industrial 15-inch touch panel PC for operator interface and manual system control Custom signal conditioning equipment with isolated voltage and current sensors to bring output signals into a range compatible with the NI cDAQ and maintain linearity across measurement ranges The NI CompactDAQ integrated into the control cabinet. The LabVIEW-based application provided comprehensive monitoring capabilities: Live visualization of the entire excitation system on a primary screen Live graphs of analog signals that could be initiated on-demand or by an external trigger Intuitive operator interface for quickly viewing data, adjusting triggering conditions, and monitoring digital inputs To iteratively improve on their monitoring system design and safely validate its performance, the research team implemented a phased deployment strategy that included multiple power plants: First deployment: Nikola Tesla A Thermal Power Plant in Obrenovac, Serbia; new excitation system for generator No. 4 (308 MW) Second deployment: Kostolac B Thermal Power Plant in Kostolac, Serbia; generator No. 1 (348 MW) Planned third deployment: Potpec Hydro Plant in Priboj; generator B (20 MW) Software front panel displayed on touch panel PC at Nikola Tesla A thermal Power Plant in Obrenovac, Serbia The research team is currently working on implementing a few features to make the system even more robust and provide even more detailed information for power plant operation teams.

These printed circuit board assemblies (PCBAs) boards require rigorous testing to validate quality and function before distribution to consumers. Learn about Cyth CircaFlex Cyth designs and builds systems for the test of PCBAs, so when they found themselves needing to test the PCBAs that their PCBA manufacturer builds per Cyth specifications. They decided to design and build a test system on their PCBACheck reference architecture. They needed a system that could perform comprehensive electrical measurements, validate individual component function, and sequence hundreds of tests rapidly while maintaining repeatability across production runs.

Project Case Study How CompactRIO Compares to a PLC Sep 17, 2024 e79a57af-b589-4f34-bcd9-3ba03d395ace e79a57af-b589-4f34-bcd9-3ba03d395ace Home > Case Studies > Programmable Logic Controller Introduction In the world of industrial automation and control systems, the choice between different hardware platforms can be a critical decision. Programmable Logic Controllers (PLCs) have long been the workhorse of the industry, but newer technologies like CompactRIO (cRIO) and Programmable Automation Controllers (PAC's) have been gaining ground. In this article, we will explore the differences between CompactRIO and PLC systems to help you make an informed decision for your industrial automation needs. Before we delve into the comparison, it's essential to understand what CompactRIO and PLC systems are and their primary functions. CompactRIO Platform Programmable Logic Controller (PLC) PLC's are specialized industrial computers designed for controlling industrial processes and machinery. They execute control functions based on logic and timing, making them well-suited for applications requiring real-time control and reliability. PLC's are programmed using ladder logic or other programming languages specifically designed for automation. PCL's have been controlling industry and processes for over 50 years, but are limited on their speed and processing power. Programmable Automation Controllers Programmable Automation Controllers (PACs) are advanced industrial control systems that combine the real-time capabilities of PLC's with the computational power and flexibility of PCs. PACs are characterized by their ability to handle complex control tasks, high-speed data processing, and custom algorithms, making them ideal for applications where standard PLC's might fall short. PACs provide a versatile platform for designing and implementing sophisticated control strategies and seamlessly integrating with a wide range of sensors and devices. Whether it's complex automation, data-intensive processing, or demanding industrial environments, PACs offer a powerful and adaptable solution for modern control and automation systems. CompactRIO CompactRIO is a PAC hardware platform developed by National Instruments that combines a real-time microprocessor, a Real-Time Linux OS, and Field-Programmable Gate Array (FPGA) technology. This platform is known for its flexibility and is often used for applications requiring high-speed data acquisition, complex signal processing, and integration with other systems. CompactRIO systems can be programmed using LabVIEW which makes Data Acquisition (DAQ) and computational algorithms very easy for engineers. CompactRIO Systems Comparison Factors Now, let's compare CompactRIO and PLC systems across various factors to help you make an informed choice: Performance Comparison PLC's are well-known for their reliable real-time capabilities, making them suitable for many industrial applications. CompactRIO, is also a deterministic and reliable real-time controller, but with a PC microprocessor (like an Intel Core Processor) offering significant processing power and flexibility. Furthermore, the cRIO includes an FPGA, which can be programmed with algorithms and logic that execute on a MHz clock iteration, meaning it can make closed loop inputs and outputs literally in nanoseconds. This makes cRIO an excellent choice for applications requiring high-speed data processing and advanced algorithms. Flexibility CompactRIO is highly flexible due to its FPGA, which not only allows you to implement custom signal processing and control algorithms, but also enables Reconfigurable I/O (RIO) which refers to the ability to swap modules and modify the I/O of the system without programming. Programming Environment PLC's typically use ladder logic or Structured Text, while CompactRIO systems are programmed using LabVIEW or other programming languages. LabVIEW comes with hundreds of engineering and mathematical algorithms and code libraries, which makes industrial and control system applications powerful with minimal programming. The result can be a fast, complex, and powerful software application that can do much more than a PLC. Connectivity Both CompactRIO and PLC systems offer a wide range of communication options. However, the cRIO's microprocessor can be particularly advantageous when integrating with industrial devices and standard networks. A CompactRIO can interact with databases, send emails, or write files to a hard-drive or a network. It can also communicate with third-party instrumentation or external devices using serial (like RS232/422/488), ethernet, or other protocols. Yet cRIO is also designed to work with industrial buses such as Modbus, Fieldbus, EtherCAT, DeviceNET, and more. Lastly, with the additional of bespoke modules and interfaces, it can handle custom communication protocols like Fiber Optic or ISM band radio. Size CompactRIO systems are compact, as the name suggests, in comparison to a computer or other larger device with similar computing power. Yet they are about the same size and shape as a PLC. Both come in various sizes, and with varying number of module slots, but larger ones can be bulkier. Cost PLC's are generally considered very cost-effective for simple control applications. CompactRIO, with its advanced processing capabilities, tends to be pricier and are generally better suited for complex control tasks where the cost can more easily be justified by the results. Additionally, cRIO can potentially save costs in the long run by reducing the need for additional hardware or complex workarounds. Conclusion In the CompactRIO vs. PLC debate, there's no one-size-fits-all answer. Your choice should depend on the specific requirements of your application. If you need real-time control, reliability, and simplicity, a PLC may be the right choice. However, if your application demands high-performance data processing, custom algorithms, and advanced connectivity, CompactRIO can provide the necessary flexibility and power. Both CompactRIO and PLC's have their strengths and weaknesses, and the right choice will depend on your unique industrial automation needs. CompactRIO Control Products NI CompactRIO Systems

Project Case Study Increasing Automation to Reduce Post-Silicon Characterization by Over 60% Sep 17, 2024 77d9d270-910e-4a59-ad72-b63610ee4da3 77d9d270-910e-4a59-ad72-b63610ee4da3 Home > Case Studies > *As Featured on NI.com Original Authors: Vinodh J Rakesh, Cypress Semiconductor Technology India Pvt. Ltd. Edited by Cyth Systems The Four-Site Automated Characterization Setup at Cypress Bangalore The Challenge Reducing the turnaround time for the bench characterization of diverse System-on-Chip (SoC) products designed and developed at different Cypress centers in Asia and America. The Solution Developing an ATE like characterization platform called CyMatrix using NI PXI Source Measure Units, PXI Matrix Switch Modules and FlexRIO modules with built-in support for up to 4X parallelism without sacrificing the flexibility or the signal integrity of a bench characterization environment. Cypress Semiconductor Corporation (NASDAQ: CY) is a leader in advanced embedded system solutions for the world’s most innovative automotive, industrial, home automation, consumer electronic and medical product applications. Our Microcontroller and Connectivity Division (MCD) focuses on high-performance microcontroller units (MCUs), analog, wireless, and wired connectivity solutions. The portfolio includes Traveo™ automotive MCUs, PSoC® programmable MCUs, and general-purpose MCUs with ARM® Cortex®-M4/M3/M0+/R4 CPUs, analog PMIC Power Management ICs, CapSense® capacitive-sensing controllers, TrueTouch® touchscreen, Wi-Fi®, Bluetooth®, Bluetooth Low Energy and ZigBee® solutions. It also features a broad line of USB controllers, including solutions for the USB-C and USB Power Delivery (PD) standards. MCD generated revenue of about $1.4B in FY2017 while serving automotive customers like Continental, Denso, Visteon, Toyota, and BMW. Time-to-Market Pressure Driving the Need for Efficient Silicon Characterization Around 2011, driven by intense time-to-market pressure and customer requirements in the mobile touchscreen market, Cypress reduced the product development cycle time drastically by following a novel IP-based design approach. This approach decreased the time taken to tape out a chip and reduced the number of bugs we identified post silicon. Because of these factors, we saw a sudden spurt in the number of new products being launched. The design team was capable of taping out more products, but the characterization team wasn’t ready to characterize all the products on time. The characterization team at Cypress is responsible for guaranteeing the datasheet specifications across PVT before releasing the product for volume manufacturing. On an average, each product has about 400 datasheet specifications. To guarantee fitness for volume production, we much measure each of these 400 specifications on anywhere between 6 and 50 DUTs. To meet the customer schedule requirements, we must complete the entire characterization of the product in four to eight weeks from silicon availability, depending on the complexity of the product. If we do not complete the characterization of the product within four to eight weeks, we risk delays in product launches, potentially leading to loss of customers and millions of dollars of business. Driven by the business requirement to be first and relevant in the market space, we knew we had to increase the efficiency of bench characterization. Left: Transition From a Bench Setup With Six Discrete Box Instruments to the Standardized CyMatrix Setup With 34 Instruments , Right: Architecture of the LabVIEW Characterization Process Boosting Characterization Efficiency by Increasing Parallelism, Automation, and Standardization of the Bench Characterization Setup The characterization team explored three ways to achieve higher efficiency: (1) increased parallelism, (2) increased automation and (3) increased code reuse/standardization. We had to scale the traditional bench characterization setups, which were limited to one DUT at a time with 50 percent automation, to achieve truly parallel characterization that gives every DUT its own dedicated instruments or at least enough instruments to allow for time-division multiplexing with > 90% automation. To characterize a typical PSoC DUT, we have to do current/voltage/timing measurements on 64 signal pins and 4 power pins. Therefore, we need 68 source measure units (SMUs)to perform all applicable tests. Factoring in a 4X parallelism, we need a characterization setup including 272 SMUs. Conventional production floor automated test equipment (ATEs) offer channel counts of this order, but they often fall short on the accuracy required for bench characterization. Besides, replicating an ATE architecture for bench is prohibitively expensive. Although a DUT has 68 pins across which the measurements must be made, the measurements need not be done simultaneously across all these pins. A careful study of all the test cases showed that, we need access to, at most, 4 signal pins and 4 power pins simultaneously. Hence, we built the entire characterization setup with just 32 high-precision SMUs, which were multiplexed across all 272 pins of the 4 DUTs being tested using a switch-matrix arrangement. The test setup includes two NI 2532 PXI Matrix Switch modules, which are 512-crosspoint switch matrices. The LabVIEW-based characterization program makes the requisite connections at run time between the DUT pins and the SMU channels based on the test requirements. The architectural diagram is shown in Figure 1. Despite the use of switch matrices, we still need 32 SMUs for the complete bench characterization setup. We ruled out traditional benchtop SMUs because they occupied too much space and involved additional cabling efforts. Instead, we chose to use NI’s PXI 4-channel SMUs, and with eight of these PXI modules, we met all the setup requirements. Some products, such as the Traveo II Automotive MCUs, could also function as multiple protocol masters—DDR HSSPI, Hyperbus, SPI and SDHC. Hence, the characterization process for these DUT variants involves source synchronous measurements. In source synchronous measurements, the DUT provides the clock and the external instrument drives the data with respect to this input clock. Measurements also included shmoo’ing the data driven by the instrument with respect to the input clock at ~100 ps resolution while being protocol aware. Conventional pattern generators, high-speed digital I/O modules, and, in some cases, ATEs do not have good timing responses to external discontinuous clocks. The timing characterization of protocol masters is best implemented with actual protocol-aware slaves that can respond synchronously to the input clock. However, these slaves do not have the capability to shmoo the data with respect to the clock. Also, using slave devices often requires the use of external discrete components such as level shifters to ensure voltage compatibility between the master and the slaves, the programmable delay chains to shmoo the delay, and so on. Such setups including multiple slave devices and associated external components are complex and prone to system-level issues. To circumvent this problem of using actual slave devices, we turned to programmable NI PXI FlexRIO product family with programmable FPGAs to emulate the slave functionality. The FlexRIO devices also allowed us to implement programmable delays with ~40 ps resolution for fine delays and ~120 ps resolution for coarse delays. The front-end FlexRIO adapter module fulfilled the functionality of the level shifter between the DUT and the emulated slave. An NI Alliance Partner, Soliton Technologies Pvt. Ltd., helped us implement the slave functionality and programmable delays on the FPGA. The transition from a single-site characterization setup to a multisite parallel characterization setup offered many benefits, so our engineering teams in Bangalore, Seattle, and Colorado immediately adopted this multisite platform. Before that, each center maintained setups with different instrumentation and had its own repository of code that was built and maintained only within these individual sites. The earlier approach limited code reuse and, at times, made replicating issues across sites difficult because of the lack of standardization in automation programs, characterization boards, and the instrumentation and interconnects. Standardization was immediately identified as the way forward, but it also presented some business constraints, like reusing existing instrumentation investments. To address this, we developed a framework based on LabVIEW object-oriented programming (LabVIEW OOP) concepts that provides an abstraction layer above the individual device driver on which we built the entire characterization automation program. This allowed engineers at different sites to seamlessly switch between instruments, such as SMUs, digital multimeters(DMMs), and arbitrary waveform generators(AWGs), from different vendors by simply editing a single entry on an Excel spreadsheet. Translating Higher Characterization Efficiency into Organizational Benefits The 4X parallelism has decreased characterization times, which has allowed us to identify and fix bugs more rapidly. The newer characterization setup has directly reduced our characterization time by over 60 percent. The characterization routine for medium-complexity products takes less than 4 weeks now as compared to 10 weeks earlier. We have also reduced the characterization time for highly complex products from 20 or more weeks to under 8 weeks. Our characterization team’s head-count has not changed much from 2011. However, the same team can now characterize more than five products in a calendar year instead of the one or two, prior to automation of the setup. Standardization and code reuse have helped us reduce the time we need to prepare for a new silicon, avoid bugs, and improve the overall reliability of the characterization setup. Though engineers and teams from multiple sites sitting in different time zones contribute to the overall characterization efforts of a product, we have seen instances when bugs reported from one site were easily replicated at the other sites by the next day. This is a true testament to how standardization has helped increase our engineers’ productivity, as they spend more time on troubleshooting the reported bug instead of on reproducing bugs.

Project Case Study CompactRIO Controls Fuel-Cell Hybrid Train Sep 17, 2024 2c864fcd-47f4-4945-9341-5619566e1124 2c864fcd-47f4-4945-9341-5619566e1124 Home > Case Studies > *As Featured on NI.com Original Authors: Tim Erickson, Vehicle Projects LLC Edited by Cyth Systems Fuel-Cell Hybrid Train The Challenge Controlling the operation of a 250-kW fuel-cell hybrid locomotive. The Solution Using an NI CompactRIO controller to monitor and control the safety and operation of a fuel-cell locomotive and controller area network (CAN) bus to communicate the engine status to the operator via a touch panel programmed with NI LabVIEW software. The prime mover of a traditional switch locomotive is a diesel engine between 1 and 2 MW driving an alternator that supplies power to the traction motors and locomotive auxiliary systems. These traditional switch locomotives require a high-power diesel engine, which typically is not fuel-efficient and has limited emission control. Subsequent design iterations of switch locomotives have transitioned to a hybrid-electric design, which reduces the overall emissions and fuel consumption because the engine can be downsized while the battery stores energy for high-power transients. However, a large source of diesel particulate pollution in urban areas still comes from diesel-powered locomotives in rail yards. To help alleviate this pollution, a North American public-private partnership is prototyping a fuel-cell hybrid switch locomotive for urban rail applications and replacing the diesel engine with a 250-kW net fuel-cell power plant, creating the world’s largest fuel-cell hybrid locomotive. Vehicle Projects LLC of Denver, Colorado, engineered the control system for the fuel cell using a CompactRIO embedded controller and LabVIEW graphical design software. Our goals are to reduce air pollution in urban rail applications, including yard switching associated with seaports, and to serve as a mobile backup power source for critical infrastructure during military base grid failures or civilian disaster relief operations. Fuel Cells and Hybrid Power Trains Fuel cells are electrochemical power devices that directly convert the chemical energy of a fuel into electric power. The cells produce electricity and water from hydrogen fuel and oxygen, which is the reverse process of water electrolysis. While fuel cells share principles of operation with batteries, they differ in that the electrochemically active materials, hydrogen and oxygen, are stored or available externally and continuously supplied to the device rather than stored in the electrodes. They are periodically refueled, like an engine, rather than recharged electrically. Like batteries, individual cells are grouped together into “stacks” to provide the required voltage or power. A fuel-cell hybrid power train uses a fuel-cell prime mover plus an auxiliary power/energy-storage device to carry the vehicle over power peaks in its duty cycle and recover kinetic or potential energy during braking. For steady-state operation, the continuous net power of the prime mover must equal or exceed the mean power of the duty cycle. Preliminary research has shown that a hybrid-switch locomotive can reduce capital and recurring operation costs. NI Compact RIO Figure 1. Top: NI Compact RIO 4 Slot Chassis. Bottom: NI CompactRIO 8 Slot Chassis. Designing a Control System Using CompactRIO We faced several design and integration challenges while developing the large hydrogen fuel-cell vehicle including weight, packaging, and safety considerations. Harsh operating conditions, especially the shock loads that occurred during coupling to railcars, required highly rugged component systems. Additionally, the fuel-cell control system is needed to communicate with the existing commercial vehicle controller to interpret operator demand and adjust fuel-cell power plant parameters to meet the power requirement. The CompactRIO embedded controller provided an ideal form factor to meet these specifications with the right I/O combination for this application. This programmable automation controller (PAC) managed and executed all power plant functions and continuously monitored the performance and safety of the hydrogen storage and fuel-cell power systems. Software Architecture Based on LabVIEW A CompactRIO embedded controller running the LabVIEW Real-Time and LabVIEW FPGA modules controls the fuel-cell power plant operation. The user monitors the control system via a touch panel installed in the locomotive cab. The control application consists of modular control algorithm VIs that communicate with each other and the field-programmable gate array (FPGA) I/O system using a tag-based architecture so that we can refer to each I/O point by the assigned name within the LabVIEW application. Each tag has properties associated with it including alarm limits, scaling (converting from voltage to engineering units), and events such as when the user wants it to log to a disk. We implemented a programmable logic controller (PLC) mentality into our PAC-based system. Developing the Perfect Control Platform with LabVIEW and CompactRIO We chose LabVIEW and CompactRIO because the NI C Series modules with integrated signal conditioning helped us implement fast monitoring of the various I/O points while connecting to a wide range of specialty sensors such as flowmeters and pressure sensors. Additionally, we performed complex control algorithms beyond simple proportional integral derivative control at very fast loop rates. Some of our control algorithms included mathematical models that we implemented with LabVIEW, which we could not have developed using less flexible environments such as a PLC platform. Furthermore, we achieved the fast loop rates that we required because we had the ability to place some of the control algorithms on the field programmable gate array (FPGA).

Project Case Study Safety Testing of London’s Underground With cRIO & LabVIEW Mar 27, 2024 42740978-590d-4734-b58e-4019f9ff187f 42740978-590d-4734-b58e-4019f9ff187f Home > Case Studies > *As Featured on NI.com Original Authors: Anthony Afonso, Thales UK Edited by Cyth Systems Thales UK using NI CompactRIO hardware and LabVIEW software to perform safety testing of London Underground rails. The Challenge Upgrading traditional methods of testing the rails used in the London underground system, which has traditionally been costly to revenue and time. The Solution Automating the testing of rails used in the London underground system and automating the communication of rail health and integrity with the use of virtual test trains (VTTs) created by using NI CompactRIO hardware and NI LabVIEW system design software. This is used to mimic an actual passenger train while saving vast amounts of time and money. History Traditional methods of testing railway systems require the use of a fully operational train and full closure of the track, usually for days at a time. The process is expensive, time-consuming to arrange, and inconvenient to the public. The automatic signaling system upgrade project for the Jubilee and Northern lines promised to boost capacity by 33 percent (the equivalent of carrying approximately 5,000 extra passengers each hour) and cut journey times by 22 percent, according to the Transport for London website. This massive upgrade offered an opportunity to revolutionize testing within the rail industry. The challenge was to generate an alternative testing solution that could alleviate many of the burdens of this traditional method and ultimately lead to a less costly and more time-efficient means of testing new technologies that is in line with the Underground’s highly stringent health and safety policy. Left: VTT in Use , Right: London Underground Our Approach Thales UK is a world leader in transportation solutions, and we were commissioned to install the automatic signaling solution for the Jubilee and Northern lines. The project involved installing a Thales S40 SelTrac Transmission-Based Train Control (TBTC) system on both the track and the entire rolling stock fleet of trains. Before these retrofitted trains could use this new system in service, the track installation needed to be tested. The engineering team devised an innovative test rig that could mimic a passenger train fitted with a Thales TBTC system. It needed to be portable and quickly assembled in almost any location along the Underground. Another goal was to reduce the quantity of test staff and test time so that standard engineering hours could be followed instead of requiring costly weekend closures. From an environmental perspective, the system needed to run reliably in any environment that could be experienced on the Underground network. This can vary from snow and rain to deep, dark, and dusty tunnels. Additionally, the solution needed to be bidirectional to offer a massive advantage during testing/fault finding, thus increasing efficiency and optimizing track time. Finally, the software needed to be intuitive to reduce the impact on test engineers during the transition from real trains to the new design. Implementation The solution was to create several VTTs with CompactRIO at the heart of each VTT system. The VTT system operates as a portable, battery-powered railway trolley that carries a testing staff and the Thales communications equipment used to test the SelTrac TBTC system. It is already installed on the Jubilee line and installation on the Northern line (the busiest on the Underground network) is due for completion in 2014, per the Transport for London website. The VTT runs with the CompactRIO control system interfaced to custom hardware. We used a CompactRIO real-time controller, an FPGA-equipped chassis, and flexible modular signal interfaces to implement the system, all of which were programmed with LabVIEW system design software. We perform both control and monitoring simultaneously with CompactRIO. For the control we use simulated signals from the interactive dials and switches on the front panel and preset values to imitate a real train. The monitoring portion of the system consists of several assigned test points, signal communication antennas, and CPU serial data, which we record from the VOBC. This platform provides the onboard SelTrac TBTC signaling equipment with the appropriate signals to mimic an actual passenger train, hence the term “virtual test train.” Additionally, gathering of all this data allows us to view how a train's VOBC would react to its surroundings. The reaction of the VOBC is imperative to us since it is this data that allows us to have confidence that the systems were installed and commissioned correctly. We also programmed data-logging functions in the LabVIEW application to easily record technical data on an SD memory card. We did this in case the data was required for the testing and commissioning of the SelTrac TBTC system. To review the test data, a VTT viewer program was also developed using LabVIEW. This VTT viewer program means that the testers on-site can review data immediately to make necessary corrections and ensure the appropriate signals are monitored. Communications Based Train Control (CBTC) Signaling System Success of the New Solution While initial trials on the Jubilee line were promising, VTTs that are now being used for routine programmed testing on the Northern line have surpassed our expectations. Use of the VTT has dramatically increased and diversified. In addition to serving as a testing tool, the VTT is a useful fault-finding tool. Another major advantage is the VTT’s bidirectional ability: A normal test train is only permitted to travel forward, but the VTT can reverse, and retest missed track, rather than loop around the line, which inevitably takes time. Another bonus is that the VTT can perform testing whilst other work is being performed in parallel. This is not possible using traditional methods because a train requires that power be available on the trackside. Besides providing the control element, CompactRIO can automate data capture. The user can test, gather data, and analyze it all in a short amount of time, which speeds up testing and commissioning. The use of the VTT has already proven to be invaluable. Traditional methods that normally take days have now been reduced to hours and require around half the manpower to operate. Our solution, powered by CompactRIO and LabVIEW, has saved vast amounts of time and money, increased productivity, and helped us take a huge leap forward in signaling testing innovation. Impact of Using National Instruments Hardware and Software A key factor in the success of this project was the use of LabVIEW. The software offered several benefits, such as graphical programming, easy-to-read code, maintainability, and scalability, that all proved essential for a large project. It also featured built-in tools that reduced development time by providing proven sections of code. Finally, the user interface design, which is usually every programmer’s nightmare, was simple because LabVIEW offered tools for quick customization. We chose NI hardware due to the versatile, reliable, and high-performance CompactRIO platform. The platform incorporates an accessible FPGA built directly into the backplane of the chassis, which was one of the most valuable features. NI hardware, coupled with the simplicity of programming the PC, real-time processor, and even the FPGA—all with LabVIEW—made us choose the NI platform. From a software point of view, LabVIEW was the ideal environment to use because of its graphical and intuitive approach to programming. It was simple enough to demonstrate sections of code to someone who had no programming experience, which helped greatly with instilling confidence in our customers and bidding to get approval. The choice of a modular signal interface meant that specification changes and revisions were accommodated by swapping the relevant interfaces, rather than abandoning the entire system. The graphical system design approach not only met our needs but also helped us remain flexible in our methodology while developing a prototype. NI customer care has always been first-class, and we highly recommend them to potential customers. Overall, from start to finish, NI provided an excellent, complete platform so that we could intuitively and easily create programs to control reliable, versatile, and modern NI hardware.

Project Case Study Automated HVAC Test System Created Using NI Tools Mar 27, 2024 64b82538-7252-4142-b2ed-90635e3a597e 64b82538-7252-4142-b2ed-90635e3a597e Home > Case Studies > *As Featured on NI.com Original Authors: Chris Hudson, ProMetric Systems, Inc. Edited by Cyth Systems HVAC System tested and controlled using the NI PXI hardware and LabVIEW software platforms. The Challenge Developing an accurate, cost-effective, multicell automated test system that continuously controls and analyzes industrial HVAC units in real-time by acquiring data from more than 1,500 sensors, simulating field, and engineering conditions, and logging all data during tests that last for months. The Solution Using NI hardware and software to create a five-celled automated test system that incorporates two infrastructure support systems with LabVIEW shared variables distributed across more than 1,500 physical I/O points to control, monitor, and report all aspects of HVAC unit testing accurately and automatically. ProMetric Systems is a national systems integration firm that provides engineering, software development, program management, and production services. One of our clients, a leading manufacturer of industrial HVAC systems, wanted to increase its market share while lowering its test and development costs for its rooftop line of air- and water-cooled chiller products. The company needed to automate its test facility and approached us with a system concept that incorporated five test cells and two infrastructure support systems. These systems required significant levels of automation, high-accuracy control, and high-channel-count data acquisition capabilities. System Requirements and Challenges Our client needed a system that could acquire data from more than 800 resistance temperature detectors (RTD) and 500 thermocouple sensors as well as various pressure, flow, and voltage sensors. The system also had to monitor I/O, log data, and provide robust, reliable functionality on a near-perpetual basis. Controlling the common support systems that service each of the five test cells was technically challenging. These systems were responsible for providing the necessary heat load and cooling mechanisms to the unit under test (UUT). Control changes or disturbances in one cell could significantly impact an adjacent cell if our solution failed to address these interdependencies. Other technical challenges involved distributed data generation, alarming at the local and system levels (including safety shutdowns), data storage, and requirements to maintain a common-core software architecture across multiple real-time cells without creating any Microsoft Windows dependencies. Left: Omega Cable Clamp Miniature Thermocouples, Right: NI PXIe-1095 Choosing NI Tools To meet our client’s needs in a cost-effective manner while addressing the demanding performance requirements, we developed and deployed a custom automated test system that simulates field and engineering conditions to accurately study the performance of the UUTs. Because our client approached us with the requirement to automate its facility, we specifically chose to base the system’s hardware on NI CompactRIO and PXI real-time hardware. These real-time platforms are ideal for making complex automated test system designs more efficient. We chose to control the system using LabVIEW graphical system design software because of its inherent capabilities for high channel counts and parallel operations. We also designed the system within the LabVIEW environment because of the software’s graphical dataflow programming, which is especially well-suited to designing large, complex systems. Left: HVAC system’s programmable logic controller. Right: LabVIEW user interface visualizing all I/O and workflow functions. System Configuration The HVAC test system we developed consists of 12 subsystems that interface NI signal conditioning hardware through an NI DAQ module. Seven of these systems direct the control mechanisms and the others direct data acquisition and test sequencing. We implemented a unique solution to the problems created by the need for two infrastructure support systems and five parallel test cells. Instead of implementing custom TCP/IP communication structures, we deployed LabVIEW network-published shared variable libraries at each CompactRIO and PXI real-time controller and interfaced them to the terminal-client PC through bound controls. This provides reliable, real-time communication for numerous I/O points while maintaining Microsoft Windows independence. Each real-time controller runs one or more Timed Loops, including subprocesses for acquisition, proportional integral derivative (PID) control, and shared variable updates. The test sequencers communicate from the test controller to the control subsystem executing on the support real-time controller by providing updated setpoints through a shared variable. Because of the flexible capabilities of LabVIEW, we were able to construct an automated test solution that incorporates more than 1,700 shared variables distributed throughout the system – across more than 1,500 physical I/O points. Using LabVIEW, our engineers also developed 40 PID loops, which control temperatures, flows, pressures, and humidity. We implemented thermodynamic calculations such as isentropic efficiency and superheat using a dynamic link library (*.dll) from NIST that integrates equations of state (EOSs) for a variety of refrigerants. The support real-time controllers communicate to system chillers and multiple variable frequency drives (VFDs) through Modbus I/O servers. In addition, each test controller deploys multiple external power analyzers through a Virtual Instrument Software Architecture (VISA) TCP/IP (VXI-11) connection. Energy, Cost, and Time Savings Our configuration saves energy because it provides heat integration between the condenser and evaporator loops. This minimizes the need for an external heat load on the UUT (except for transitory step changes) by controlling the flow of fluids through the loop interface heat exchanger with PID modules written in LabVIEW. Because it saves energy, it will also save our client significant costs because the company runs long-duration tests on a continual basis. The system also saves significant time in the test setup process because it incorporates not only fully automated functionality but also an easy-to-use graphical programming interface. This eliminates the need for operators with programming experience and contributes to increased supportability and reliability. The system includes seven operator workstations (OWSs) that can remotely communicate to any of the 12 real-time controllers. These workstations provide a window into the test, control, and data systems while helping the operator easily start, stop, or configure tests. Once an operator starts a test, the OWS is no longer required unless the operator wants to stop or monitor a particular test or system. The system’s automated data-logging functionality uses the transition minimized differential signaling (TMDS) file format, coupled with an FTP transfer mechanism, to store test information on a multiterabyte server. Conclusion Using NI products, we successfully designed and developed a highly accurate, reliable system that helped our client efficiently study the behavior of its HVAC units while saving energy, time, and capital. Additionally, using NI products helped save our company significant development time in designing and deploying the system because the network-published shared variable eliminated the need for custom TCP/IP data transport logic. Because of the tight hardware-software integration of LabVIEW, CompactRIO, and other NI tools, we developed this test system within just eight months, a process that would have taken well over a year using traditional solutions.

Researchers require thousands of consistently prepared test slides with exact viral concentrations to develop flu vaccines or understand the transmission of respiratory diseases. The manual preparation of virus-coated slides can slow critical research and expose laboratory personnel to risk because of the continuous handling of infectious materials. For biopharmaceutical R&D labs, testing throughput directly impacts their research timelines and discovery rates. To accelerate their research and bring treatments to market faster, researchers need an automated solution that can handle infectious materials safely and rapidly prepare viral samples. Manual Sample Preparation Bottlenecks A biopharmaceutical R&D company faced a serious bottleneck in their respiratory desease testing program due to the manual dispensation of viral samples by laboratory operators. Operators were dispensing eight different viral samples, including rhinovirus, influenza, and SARS, onto individual test slides, one by one. This manual process grealy limited their resting capacity and created safety concerns for operators handling infectious materials at scale. Their existing workflow could only produce a fraction of the test slides they needed to support their research initiatives, which created delays in their studies and greatly limited their ability to scale their programs effectively. This biopharmaceutical R&D company decided to collaborate with Cyth Systems to build an automated slide coating solution because of their expertise with industrial automation and precise mechanical control. Industrial Automation and Robotics Cyth engineered a fully automated viral dispensing system that integrated precision robotics, multi-channel pumping, and biological safety containment. Cyth designed a complete automated workflow to transform their inefficient, manual processes into a high-throughput and safety-focused operation. Core System components: Heated stirring plate for maintaining suspension of eight distinct viruses in liquid mediums 16-channel peristaltic pump for delivering precise viral volumes to nozzles for dispensation onto a slide Denso 6-axis robot arm for managing slide po sitioning with 5-30μL dispensing accuracy (±10%) Indexing rotary table for transporting coated and dried slides to a rack for storage Biological Safety Lever II cabinet for containing infections materials Advanced Process Architecture built on NI Labview and TestStand: Supervisory processes built on LabVIEW programs orchestrated by NI TestStand software. NI PXI chassis delivers high-speed I/O and Modbus/RS485 communication capabilities to coordinate system hardware. Precision Robotic Control through Machine Vision: Sick proximity sensors and high-resolution cameras identify available positions on the drying rack. Comprehensive Safety Intgration: Emergency light curtains trigger immediate halt to process hardware if the enclosure is breached. The Biological Safety Level II (BSL-II) cabinet uses laminar airflow to contain all viral particles and prevent contamination of samples. Learn about LabVIEW Software Consulting Workflow steps: Robot arm retrieves clean slides from supply stack Heated stirring plate (1) prepares viral content for dispensation; eight distinct viruses were suspended in a liquid medium. 16-channel peristaltic pump (2) delivers virus suspensions to dispensing nozzles. Denso 6-axis robot arm (4) picks up an available testing slide (3) and positions it underneath the nozzle to be coated in the suspension, then the arm transports the slide to a drying rack Indexing rotary table (5) transports completed and dried samples to an available rack with storage for up to 1000 samples 1: Heated stirring plate. 2: 16-channel peristaltic pump. 3: Stack of clean slides. 4: Denso 6-axis robot with custom-fabricated gripper. 5: Indexing rotary table with a drying rack for slides. Sample Preparation Throughput Tripled Production efficiency gains: 300% increase in test sample preparation throughput 1,000 slides produced every 2-hour cycle Continuous operation with minimal manual interaction from operators Enhanced safety: Complete containment of infections materials achieved adhering to BSL-II protocols Eliminated direct operator exposure to viral samples Emergency stop enables immediate operator intervention as needed Research acceleration: Increased access to high-quality samples greatly increased biopharmaceutical research testing capacity Consistent dispensation of slide coating improved reliability of research results Reduced slide preparation time allows researchers to focus on analysis rather than sample preparation The automated system has positioned the biopharmaceutical R&D company to scale their respiratory disease research programs significantly, enabling them to accelerate the development of treatments. The enhanced safety protocols, combined with increased sample preparation throughput gave the R&D company a competitive advantage when securing research contracts and advancing their pharmaceutical developments.

Project Case Study Nucor Refines Steel Recycling Using NI Hardware & LabVIEW Aug 29, 2023 0d667412-79ba-41a3-9b9b-5fe006c801c7 0d667412-79ba-41a3-9b9b-5fe006c801c7 Home > Case Studies > *As Featured on NI.com Original Author: Dave Brandt, Nucor Corp Edited by Cyth Systems Steel recycling facility The Challenge Developing an automation system for a steel recycling facility that reduces the amount of energy consumed to comply with statewide energy regulations while improving the safety and efficiency of the plant. The Solution Using National Instruments CompactRIO and the NI LabVIEW graphical programming environment to develop plant automation solutions to accurately measure the amount of energy required to recycle steel and improve facility safety. Two out of every three pounds of steel is produced from previously used steel, making it the most recycled material in North America. Recycling steel consumes between 60 and 74 percent less energy than producing new steel from raw materials, which is equivalent to the amount of energy needed to power 18 million homes for one year. Improving Steel Recycling Steel companies are constantly refining their recycling operations to make the process more efficient and environmentally friendly. At Nucor, we place a high value on being stewards of our environmental resources, and to that end we have become the largest recycler of steel in North America. In 2005, we purchased the Marion Steel Company in Marion, Ohio, which gave us a location central to nearly 60 percent of the steel consumption in the United States. To maintain our high facility standards with this acquisition we immediately recognized the need to implement a facility automation system to improve the efficiency and safety of the plant. Top: NI cRIO-9063 Bottom: NI cRIO-9038 Reducing Energy Consumption with NI Software and Hardware At the Marion facility, we manufacture a full line of rebar, sign supports, delineators, and cable barrier systems using recycled steel. During the steel recycling process scrap metal is heated in an electric arc furnace (EAF) and, depending on the type of steel being produced, a combination of elements is added to the viscous steel to create the appropriate steel alloy. This process requires large amounts of energy that vary significantly depending on the amount of scrap placed in the furnace. When we purchased the Marion facility, operators relied on estimates to determine the amount of steel placed in the furnace, causing the metal to be overheated oftentimes. This results in an unsatisfactory end product that must be recycled again, which costs the company time, money, and energy. Steel furnace To reduce the number of reheats, we developed a low-cost scale and weighing system using LabVIEW and NI CompactRIO controllers that accurately calculated the amount of steel in each burn. Knowing the exact amount of scrap metal placed in the furnace allowed us to precisely calculate the amount of electricity required to heat the furnace. Prior to implementing this scale system, our steel measuring was hit or miss. We did not have a method of tracking the number of reheats prior to the implementation of the new system, however out of the more than 6,000 batches in 2007 after deploying the new system we only performed 10 reheats, which was far less than in 2006. Eliminating Flicker with LabVIEW and NI CompactRIO One risk involved in drawing the large amount of electricity required to heat the furnace for recycling is causing flicker on the power grid. Not only did we receive monetary penalties for using too much electricity, but the power grid flicker was an inconvenience to Marion residents. To reduce electricity consumption, we developed an online reactor in series with the furnace using the LabVIEW FPGA module and the CompactRIO platform that measures the amount of energy drawn from the power grid. If the furnace approaches the prescribed limit, the system can quickly change control methods to reduce the amount of power being drawn. Improving Facility Safety with LabVIEW One of our core values at Nucor is employee safety, thus another goal of our facility improvements was to make the Marion location a safer place to work. We determined we needed to upgrade the method for turning the EAF on and off. Before renovating the system, an operator had to manually pull the on/off switch, which made him or her vulnerable to injury if the fuse were to blow. A cRIO and an HMI were used to create a remote power switch that does not put operators in potentially dangerous situations. The Benefits of Factory Automation Using NI hardware and software, we developed a variety of automation systems that have greatly reduced the electricity we use and eliminated potential safety issues at our Marion, Ohio facility. The ability to have one platform handling all of our communication protocols (Ethernet, serial, Modbus, and EtherCAT), PID control loops, and sequencing algorithms saved us time and money. With LabVIEW’s graphical system design, we were able to further simplify our development by parallelizing all of our communication and control loops, which lead to increased system performance in addition to readable and maintainable code.
