Functionality

The time delay off, eight channels, function TOFGAPC can be used, for example, for
a drop-off-delayed output related to the input signal. The function 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.
