The instruction is executed when the
value of this variable changes to
TRUE.
Other input variables are also input
when Execute changes to TRUE.
If input values are changed, they will
be updated when Execute changes
to TRUE again.
The output variables are valid as
long as Execute remains TRUE
even after the instruction is complet-
ed.
Then, all output variables except for
Error and ErrorID are disabled when
Execute changes to F
ALSE.
If Execute changes to FALSE before
the instruction is completed, output
variables are valid for at least one
period.
