RNRP no controllers listed
A new system has been loaded with 800xA v220.127.116.11, however the controllers on the control network are not visible in RNRP. They are visible in the OPC server and are able to download to them. All the data is availabe in the system.
Do you know what could cause this issue?
Client Server Network Range 172.16.28.XX
Control Network Range 172.16.104.XX
The default RNRP settings are used.
If you installed the Base software properly the firewall exceptions in Windows should be loaded for RNRP.
It sounds like their is some setting in network switches. Have you checked multicast settings? Multicast traffic have to be enabled for RNRP to work, it is not default settings on all switches.
Good luck with your network.

If you are using different network areas for plant network and control network, make sure “Enable TCP/IP Forwarding” is true (1) in RNRP setting of that particular connectivity server. This enable connectivity server to act like as router node. To make a change of this parameter effective the node needs to be restarted.
