1
This Override action only occurs when the device is in the Executing State.
2
Available for Pressure Controllers Only.
3
This parameter is only configurable when the device is in the Idle State (i.e. when the device is not being actively scanned/polled).
4
This parameter will automatically be set based upon the inferred data type of the selected Assembly used for I/O (i.e. if an Assembly is
selected that contains Setpoint as one of its data members, and the inferred data type of the assembly is INT, then this attribute will be
automatically set to INT once I/O data exchange begins).
