Hi everyone,
I’m new to B&R and currently setting up a redundant system using X20CP3684 controllers. I’m facing two issues:
-
Modbus_TCP_Any: It only works on either the primary or the secondary controller — never both at the same time. When one is OK, the other reports an error.
-
OPC UA Server: I want to provide data points to another monitoring system (Tridium Niagara) using the cluster IP, but it only works when I enter the primary IP. It doesn’t seem to respond through the cluster IP.
Could this be due to a configuration issue, or is there something I’m missing in the redundancy setup?
Any guidance or examples would be greatly appreciated.
Thank you for your help!
