To replicate the MPT single process in MP, the designer must
create one runtime control, three activities and tie them together
with one variable.

These are equivalent, except for the trigger continuously mode.

These are equivalent, except for the trigger continuously mode.

Program Event

These activities cover similar functionality: triggering periodically
based on calendar date, day of the week, or time. However, the
approach to specifying this information is different.

Periodic Time Event

These are equivalent, except that MPT gives the test designer
flexibility on whether or not to log a message and its severity.

MPE always logs a message with the severity level of
Informational.

In MPT, several event processes can trigger and remain active
to trigger again. MPE does not have an equivalent concept. The

Functionally equivalent. MPT specifies a single pulse width for all
outputs. MPE allows a separate pulse width for each output.
