Functionally equivalent. Dwell Dwell Command
The MPE activity has the following enhancements:
• More flexible termination criteria (MPT only has duration).
• “Dwell at Current Value” is the only MPT implementation. In MPE,
clearing this property allows the designer to specify the level at
which to dwell.
Functionally equivalent. Profile Profile Command,
Profile Command
with ALC
• MPE does not implement the “Manual Compensation” option.
• MPE supports profile counters by assigning them to variables. If
the operator needs to see the values, the test designer must add
“Variable Meters” to the runtime display to show these variables.
• In MPE, all actions and counters must be listed in the “ActionList”
in the header of the profile file. In MPT, this ActionList is optional.
This may require you to modify your MPT Profile file to use it with
MPE.
Functionally equivalent. External
Command External Command
MPE allows the designer to specify the signal that represents the
external signal. In the MPT application, the external signal had to be
specified in Station Builder.
When the MPT process finishes and setpoint or span is disabled, it
returns the disabled control to the hardcoded value (0.0 egu for setpoint
or 100% for span). In MPE, setpoint and span remain at the values
specified in the activity.
Functionally equivalent. Sweep Sweep Command
In MPT, this is also called feedback-based command. Not available Signal Based
Command
MPE does not support this.
Functionally equivalent. Time History

• MPE does not support Automated Playout Protocol (also called
XTEST).
• In MPT, the units for acquired data are taken from the calibration
information for this signal (defined in the Station Manager
application). In MPE, the test designer selects a Unit Assignment
Set (which may be from a variable).
• MPE does not support RPC II drive files.
• MPE does not support the Taper Starvation option.
