S7-1500 R/H Driver Fails to Reconnect After Network Restoration

[Mgiacome]

Hello,

I have an S7plus driver configured as an S7-1500 R/H Single with two CPUs having different IPs. I am using TLS with a certificate, and the redundancy switch condition is set to Opstate/ConnState.

If I disconnect the *master CPU* from the Ethernet network, the driver successfully continues to communicate with the *slave CPU*. The driver status shows "*logged out*" next to the disconnected CPU.
However, when I reconnect the CPU to the network, the driver makes no attempt to reconnect and remains *logged out*. This causes me to lose redundancy.

Is there a way to resolve this, or any configuration I need to modify on the driver side or the S7-1500 side?

Thanks

Best Regards
