Redundant Ignition Backend Gateways with KepserverEX

Ignition
1

Hello All,

I have redundant gateways with kepware installed on each gateway. Intention is to allow Ignition to have connection to kepware in the event of the primary gateway going down. Has anyone done something similiar I am wondering what the best approach is here? I am concerned about the connection not functioning after a failover occurs due to untrusted clients, etc. I am using OPCUA and not OPCDA

Thanks,

Frank

Point the OPC UA connection at opc.tcp://localhost:49320, it'll attempt to connect on both primary and backup. You'll have to go accept Kepware's server cert on the backup, and accept Ignition's certificate in both Kepware instances.

Don't use any of the settings in the "Failover" section of the OPC UA connection.

Hello Kevin,

Will do. Thanks for the information.

Hello, Circling back to this topic with another question. If the Kepserver is installed on two remote servers what is the best way to set up Ignition to use one as a primary and the other as a fallback secondary?

Thanks,

Frank
