I have 24 Siemens Siprotec relay(7sj62) which i want to communicate with Scadapack 330E (Schneider) on 103 Protocol.
but every time I try to communicate it shows Slave device is failed to communicate. trying to communicating via serial (RS-485).
What should i do..?? or do i need to communicate it with Siemens PLC..?? If so which PLC should use..??
