Compact HMI V5.1 OPC Communication Failure
Compact HMI 800 V5.1 OPC Server communication failure immediately after giving "deploy" and all the signals showing "Bad" status. The communication restore after the system restart or manually disconnect & connect the controller in the OPC Server for AC800M. Can any one know how to fix this.

unfortunatelly I cannot tell you how to solve this issue but I saw the same behaviour, not after each and every deploy, but from time to time.
I want to mention, that it looks like that the communication is still working but the values need to change their state.
My work arround was, to disconnect the ethernet cable of the AC800M and reconnect it again
