Connections to S7-400h devices

I find to configuring ignition communication with a Siemens S7-400h, so HW redundancy. Is there a configuration procedure? In the Driver configuration I don’t see where I can put the address of the secondary PLC, that in case of lost communication with the primary PLC swith on the back-up PLC.
Best regards

Ignition Siemens driver doesn’t support redundancy.
In order to achieve what you want, you must use third-party tools.
For example this last post:
is talking about Kepware’s OPC Server Media level redundancy.
