Cyth Saves a Company's RTD Calibration

Cyth Saves a Company's RTD Calibration

Calibration - specifically in regards to measuring instruments - has two objectives. One, it checks the accuracy of the instrument. And two, it establishes the traceability of the measurement. Like with any scientific instrument, the accuracy of measuring devices degrades over time. This is commonly caused by wear and tear but also can be caused by an electric shock or a hazardous manufacturing environment. Whatever the case may be, calibration is an essential aspect of engineering that cannot be looked over.

In the start of 2016, a large electrical manufacturing company based in San Diego approached Cyth with an issue all too familiar. This company, specializing in semiconductor inspections, had a Resistance Temperature Detector (RTD) that measured the temperature of a semiconductor by correlating the resistance of the RTD with the temperature of the semiconductor itself. Yet the issue wasn't with the RTD, but with the cFP (Compact FieldPoint).

In the winter of 2014, National Instruments began their discontinuation process for their Compact FieldPoint (cFP). Essentially, the cFP is no longer manufactured, if one wants to buy a cFP they need to submit an order request. If the request is approved and they receive their cFP, it will be supported until 2021. After hearing NI's news, this manufacturing company was faced with two options: migrate their RTD's LabVIEW code to NI's Compact DAQ (cDAQ), or migrate their RTD's LabVIEW code to NI's Compact RIO (cRIO). Not knowing the first steps to take, they contacted to Cyth.

They explained how their PC was running on Windows and making calls with the cFP. After hearing this, it was clear to move the LabVIEW code to a cDAQ rather than a cRIO. Yet there were two components the client asked for making this straightforward task more complicated than originally thought. The client asked for analog input modules, and relay modules on their cDAQ. Which means not only did Cyth have to migrate their LabVIEW code, Cyth had to modify their code to adjust for these specific needs as well. On top of that, Cyth had to replace all their cFP drivers too. Which meant anywhere a cFP would be called, a cDAQ would be called instead even though it was executing the same command (either acquire analog input data or control the relay outputs).

Although the project may sound straight forward on paper, it's anything but when dealing with cFPs. The truth is; migrating LabVIEW code from an obsolete cFP to a high-speed cDAQ is not an easy task, especially when other components are added. In fact, many companies - in trying to do it themselves - prove to be unsuccessful when migrating code from their cFP without any other factors considered. But for this San Diego semiconductor manufacturer, knowing Cyth could not only migrate their code but understand what it's doing and why it's doing it, brought them a lot of comfort.

From the conception of this Compact FieldPoint project to the end, both parties were extremely happy with the partnership and the results. Migrating LabVIEW code from cFPs is a prevalent issue for many companies in a variety of fields. But knowing Cyth is available, knowledgeable, and successful is a fact that turns the tides for companies and integrator around the world.
