Error in Profibus communication of PM572 PLC with Yokogawa DCS
I am trying to communicate a PM 572 PLC as slave with yokogawa DCS on profibus. I m using PDP22 connector for the purpose. I have assigned the node address as 3 and same is given to yokogawa engineer. The PDP22 connector is showing a red LED flashing which indicates the bus is unhealthy. We have checked the wiring is alright. DCS engineer also configured the settings after importing our GSD file but the bus is not getting healthy. what are the possibilities and remedy?
