Redundancy in CoDeSys HMI

Hello all,

In my redundancy project with two PM591 PLCs, I have used PS541 for the HMI. The problem I encountered in the runtime is when the online PLC fails (i.e. PLC A) and the other PLC (i.e. PLC B) becomes the primary PLC, in CoDeSys HMI I can not follow the outputs until the online PLC (PLC A) becomes the Primary PLC again. In fact how I can observe each PLC in CoDeSys HMI when it is the primary one?

Thanks in advance
