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 […]

This was a frequently asked question at presentations of our solutions for LabVIEW fieldbus connectivity. Now we can answer this question ‘yes’ for LabVIEW RT on NI Linux Real-Time. To make physical integration as easy as possible, we initially limited the hardware options to netHOST LAN gateways.. In the first development step, our libraries enable […]

With Industrial Communications for EtherCAT and the EtherCAT master available with it, NI has created a powerful interface for integration into industrial environments for its compactRIO PAC family and, with EtherCAT, NI has chosen what we consider to be the most powerful and flexible Real-Time Ethernet bus. A wide range of sensors and actuators can […]

Once again, we would like to thank NI for the opportunity to present our DIAdem-based turn-key solutions for various applications to interested users. We have shown automated data acquisition and evaluation on vehicles the end-of-line testing of pneumatic valves and our real-time extension of DIAdem based on TwinCAT. “Automation saves us 30% time – every […]

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.

It is by far the most widely used PLC in Europe – the Siemens S7. It is therefore not surprising that it is also used on many test benches for both central and peripheral tasks.

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.

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 […]

The use case is typical: many sources provide data that is evaluated in a standardized way and then used by a group of users.
