MPE supports PRO SEQUENCE but does not support the old RDSURF
files.

MPE does not support assigning a control mode selection to a variable.

Ramp, Cyclic,
Dwell, Sweep

Segment, Cyclic,
Dwell, Sweep

MPT allows a single process to be used for different control modes
(selected by a variable). This requires the activity to retain
mode-specific information for each control mode (not just the selected
one).

This feature can be simulated using an IF-ELSE activity and multiple
command activities.

In MPT, specifying indefinite cycle count is a check box to the left of
the count property label.

Cyclic, Sweep

Cyclic, Sweep

In MPE, you must specify an arbitrary large number.

Term

MPT and MPE handle acquired data differently.

All Data
Acquisition
processes

MPT collects data directly into a file available to the user. The file is
localized (such as display names, comma decimals, and so on). The
data can be tab, space,or comma separated. The user is responsible
for manipulating this file.

MPE collects data into an internal (XML), language-neutral format. It
can be manually (or automatically) exported into a more user-friendly
localized format.

Because of this difference, many options that MPT has for specifying
the content and format of the acquired data file are implemented in
MPE as options for how the file will be exported (such as units, column
ordering, and so on)

Also, MPE supports including raw data in a report. Because reports
can be CSV files, this can be used to export raw data (as well as
calculated data).

MPE does not have a way to export data into the MPT data format.

Specifying the order of data acquisition signals can be done in the
export process.
