Hello,

Looking for some help configuring a gateway A (server) to gateway B (client) OPC connection with redundancy… I’ve managed to connect the A.master server to the B.master client – but it doesn’t appear that the connection get’s replicated on the B.backup client. Doesn’t appear that I can add it manually on the B.backup machine (tells me to configure the master!).

on the master:

on the backup, after forcing synchronization:

Any ideas? Was looking to avoid placing the B.backup machine into independent mode… but perhaps this is the only way?

Thanks in advance for any help!
