I/O module
RS485, SPI | cRIO PB
COMSOFT
The COMSOFT cRIO PB module connects the CompactRIO chassis directly and for the first time to PROFIBUS DP networks.
The cRIO PB module features cyclic DPV0 Master class 1 services for the fast exchange of I/O data as well as acyclic DPV1 Master class 2 services for configuration and diagnosis purposes. The module additionally supports DP Slave mode for the integration in existing PROFIBUS DP networks, e.g. in combination with a PLC.
The small sized and rugged platform CompactRIO from National Instruments is a control and acquisition system designed for applications that require high performance and reliability. Using FPGA technology (Field Programmable Gate Arrays) the implementation of hard real-time-enabled systems is also possible. cRIO is a modular system and there is a wide range of industrial I/O modules available. This results in combination with the cRIO PB module in an extremely attractive solution for the realisation of PAC systems implementing high-complex data acquisition and control functions at the same time.
A direct LabVIEW™ VI interface for a seamless integration of the module and a full graphical Windows based PROFIBUS DP configuration tool are available.
The easy-to-use VI interface provides detailed examples incl. source code for DP Master and DP Slave.
