9.8.2 Functionality
The time-delay-off function block TOFGAPC can be used, for example, for a
drop-off-delayed output related to the input signal. TOFGAPC contains eight independent
timers. There is a settable delay in the timer. Once the input is activated, the output is set
immediately. When the input is cleared, the output stays on until the time set with the Off
delay time setting has elapsed.
