Take a look at the functions called:

ServerInfo - Gets status information on clients and servers

IOdeviceInfo - Gets information about a specified I/O device

You should be able to do everything you need to with these.

alternatively you could create a watchdog count between the PLC('s) and each Server and if one server doesnt respond then you can call up a tag on the other server to give a status.
