3.14 The function block TOF
3.14.1 Functional description
FB TOF is used to realize a switch-off delay. Logic 1 at input TofIn is transferred to the output with a set
delay time. The output remains activated if the input is set to 1 again before the switch-off delay time has
elapsed.
The error output is inactive since the function block sets no errors.
The maximum switch-off delay is 6000 x 100 ms (10 minutes).
