Forcing
Through forcing, you can compel input and output signals.
Actual input signals or status changes by program are
ignored and replaced by the force values.
Warning
High acceleration forces at the connected actuators!
Undesired movements of the actuators can cause
collisions and severe injuries.
·
Be very careful when forcing in order to avoid undesired
movements of the actuators.
·
Make sure that no persons are in the operating range of
the drives or any other connected actuators.
Forcing of inputs with
handheld type CPX−MMI
Forcing an input does
not modify the input signal itself and
cannot be observed at the relevant status LED. The logical
status of the input changes internally and in some cases has
an effect on the program. The forced input status is transĆ
ferred to the image table of the inputs. The online display in
CoDeSys provided by Festo therefore shows the forced input
signal.
Forcing of outputs with
handheld type CPX−MMI
Forcing an output does modify the actual output signal and
can be observed at the relevant status LED. However, the
forced output signal is
not transferred to the image table of
the outputs. The online display in CoDeSys provided by
Festo does
not show the forced, physical output signal,
but the status from the image table.
