The requirements for connecting devices to industrial buses are as varied as the tasks that can be solved with NI-PAC compactRIO. While the controller must be a bus master for connecting sensors and actuators, slave interfaces are usually easier to connect to an existing PLC. Control tasks require real-time behavior with low latency, while for […]

Last week, we presented our new fieldbus interface for compactRIO live for the first time at the Würzburg LabVIEW User Group (WUELUG) meeting at Siemens Energy in Nuremberg. And since we were guests at Siemens, we of course demonstrated the connection to a device with PROFINET interface, an electro-pneumatic valve from Emerson Aventics’ Advanced Valve […]

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.

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.

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.
