Fig. A.2 Influencing input signals
Forcing an input does not modify the input signal itself. The logical status of the input only changes
internally and may be effective in a program.
Obtain further information on Fail safe and Force from the following sections.
A.1.1 Force
Fundamentals
The function Force permits the manipulation of signal states independently of actual operating condi­
tions. Force enables input and output signals to be overwritten. Input signals actually present or
changes in status by the program will be ignored. The input signals actually present and the output
signals generated by the user program only become valid again when the Force function is deactivated.
Warning
Uncontrolled movements of the machine and the system resulting from manipulation of
signal states.
Injury to people, damage to the machine and system
• Observe notes regarding the "Force" function in the "CPX system description"
(è Tab. 1).
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.
