Fundamentals
The function Force permits the manipulation of signal states
independent of actual operating conditions. Force enables
input and output signals to be overwritten, Input signals
actually present or changes of status by program will be ig
nored. The input signals actually present and the output sig
nals generated by the user program only become valid again
when the function Force is deactivated.
Warning
Depending on the functions of the machine/system, the
manipulation of signal states can lead to serious personal
injury or material damage.
Use the Force function very carefully, in order to avoid
damage.
The Force" function is used mainly in the commissioning
phase in order to set certain signals to the desired status for
test purposes even if the wiring is not complete.
