When connecting to KepServer, some versions may not allow anonymous connections by default. Both the Backup Discovery URL and Backup Endpoint URL properties need to be configured.įor additional information on Failover, refer to OPC-UA Connections and Settings. The Backup properties should be used when a pair of redundant Ignition Gateways are trying to look at the same Kepware OPC-UA server. To enable failover, check the box to Show advanced properties in the New OPCUA Connection Settings, set the Failover Enabled property to 'true,' and specify the Failover Endpoint. The failover Kepware OPC-UA server will be used in the event the primary Kepware server goes down.

Now the OPC Server Connections page shows the Status of Kepware to be Connected. On the OPC UA Configuration Manager window, go to the Trusted Clients tab, click on Ignition OPC-UA Client, click the Trust button, and click Close. The OPC UA Configuration Manager will appear.
