In M580 Hotstandby system, Read_VAR freezes when the system swaps

The reason is that you probably exchange the 4 Communication Management Parameters words between the Primary CPU and Standby CPU. They should not be exchanged between Primary and Standby.

De-select the "exchange on STBY" attribute for each of the four management parameters
Insert a value for the fourth management parameter ("length")
