Opc redundant configuration

it is possible to associate a tag with two ‘opc item path’
I wanted to have a redundant opc configuration, and associate a tag with the two connections.

thanks you

There is nothing built in to do this.

You could try to monitor the connection status in whatever way is meaningful to you and when you detect that it’s time to fail over edit the OPC tags via system.tag.configure to update the OPC Server and/or OPC Item Path.

A workaround solution could be to use 2 OPC tags, one for each source, and a reference tag.
You will have to write the source path of the reference tag to select the first or second OPC tag according to a watchdog Logic.
