Switch-off delay
FS outputs can be switched off with a delay. Even if the process image of outputs switches
from "1" to "0", a "1" signal may remain at the output for the duration of the delay. If there is
another "1" signal during the switch-off delay, the switch-off delay time is reset again and
restarts at the next "0" signal.
In the event of external errors, e.g. if the connection to the controller is lost, the output is
switched off after the set switch-off delay.
However, in the event of internal module errors, the switch-off delay cannot be guaranteed.
Default value: 0 ms (immediate shutdown).
