Backup CODESYS controller

We have an existing system with an EPIC running CODESYS controlling HVAC equipment with RIO modules.

Is it possible to install another EPIC as a backup? It doesn’t need to be a fast switch - just need it to be automatic.

Possible? Yes.
A check box option? No.

Currently we no plans to offer a redundancy option.
A few folks have mentioned it in the forums, you might get some starter ideas via a search.
