hello,

in my project i have 2 x20 plc working in redundancy, i want to get all the information from both PLC from the combined IP via OPC UA through my SCADA.

for example to get the ETH port statistic information for the standby PLC. is there a way to do this?

You would need to communicate the information to the active PLC from the standby PLC in some way.

An easier way would be to connect separately to both PLC’s using their own IPs for data, that is related to a single PLC.
