Using PM591 AC500 plc with PP877 on Profibus but not communicating
I am using PM591 AC500 Controller for communicating with PP877 on profibus and
Set address as 4 at PM591 side, using CB802 module,
I think I have done settings correctly, but still I am not able to communicate with PP877 over profibus, do I need to do some settings in PP87 also like node address.
I can share my backups if required.Pls give your suggestions for no communication.
