I am using two RevPi Connect+ controllers and I want to make a redundant system. For that I am using Redundancy Configuration module. When I setup everything according to the manual, PLC 1 is always in 'Simulation' redundancy state. When I try to Activate it I get an error 'Switching simulation to standalone failed'. Also I can't synchronize the PLCs: 'Synchronization failed'.
The project is downloaded to both PLCs and they are in Run state.
