Working Principle The module plugs into VME chassis slot and communicates with host controller over VME backplane. Onboard processor runs PROFIBUS-DP protocol stack. It exchanges cyclic input and output data with all PROFIBUS slave nodes on fieldbus. Process data received from field devices transfers to VME host memory, and control data from VME host transmits to fieldbus slaves. Module monitors bus communication quality and reports fault status to host system.
Installation Requirements Insert card into standard 6U VME chassis slot and fasten front panel screws; Use PROFIBUS shielded twisted pair cable; Terminate bus ends with PROFIBUS terminator; Connect chassis protective earth; Separate fieldbus cable from high voltage power wiring.
Precautions for Use Set PROFIBUS station address before power on; Check bus termination resistor installation; Do not exceed maximum PROFIBUS cable length corresponding to baud rate; Perform bus diagnostic after commissioning; Avoid electrostatic discharge to PCB before installation.
