Modbus / Does MACH have Modbus monitoring . . i.e. a way to see if Modus is running OK?

Trying to find a way to notify user if modbus connection dies for any reason.
Docs on MACH's modbus implementation are sparse and I don't find any way to query MACH for Modbus status.
The application is to be able to E-stop MACH from an external source if the Modbus com stops for any reason.
If it is not possible to query MACH, then what methods are people using to monitor the connection?
A character could be sent and retrieved by the slave and a hardwired signal used to notify the user of a problem, but it seems there should be a way to query MACH.
