associated with the information object.
Monitor Point # - This is the Information Object Address of the associated
Monitor information object to be sent to the Client once the Control request is
received.

object to be sent by the MVI56-101S module when it receives the command for
that specific information object.
Require Select - This parameter configures the information object to require a
Select request before the Operate command.
