According to the NI website, DIAdem is ‘… is high-performance software for seamless test and measurement data management, exploration, analysis, and automation’. What we and many of our customers feel is missing is a reference to DIAdem’s measurement and control capabilities, which make the software unique as a whole. While DIAdem supports a wide range […]

Testing sensors and actuators with fieldbus interface means first and foremost being able to handle a variety of different buses – in addition to Real-Time Ethernet, also “wired” fieldbuses such as Profibus and CAN / CANopen and the IO-Link communication system – and to be able to switch between several buses in one test system. […]

25 years ago, NI acquired GfS Aachen and added its flagship software DIAdem to its portfolio, ensuring its worldwide distribution. During this time, DIAdem’s data management capabilities have been consistently developed further – just think of the TDM data model, the DataFinder and the DataPlugIns, which make any data format accessible. At the same time, […]

Once created, most fieldbus applications remain unchanged – the bus topology rarely changes and the protocol never does. The situation is quite different on test benches where devices with different bus interfaces are tested. Unless separate hardware and software is to be installed for each bus protocol at great expense, the only remaining option is […]

Unlike other real-time Ethernet buses, Profinet requires station names and IP addresses for slaves (IO-devices in Profinet nomenclature) in order to communicate with them. However, since these parameters are assigned on an application-specific basis, they are usually not available for Profinet devices that have just been manufactured and are now undergoing end-of-line testing. However, since […]

As we have already mentioned here, while LabVIEW is inherently strong at connecting analogue and digital signals, special solutions are required for communication with fieldbuses, such as our interface for the real-time Ethernet boards of Hilscher’s cifX family. Sometimes, however, a complete fieldbus connection is not necessary and it is sufficient to connect intelligent sensors and […]

This amount of data must be processed by one of our evaluation applications for test bench data. Only a handful of characteristic parameters remain from complex time curves and a million measurement values. And only these parameters – and, above all, their changes over the course of the test, which can last days or weeks […]

That’s what the project manager at Volkswagen says about our solution for recording and evaluating quiescent current measurements in motor cars. How does it work? Through consistent, end-to-end automation. All the information is obtained from the test order system in order to automatically perform both the respective measurement and the associated evaluation. The parameter structure […]
