3.12 The function block TON
3.12.1 Functional description
FB TON is used to realize a switch-on delay. Logic 1 at input TonIn is transferred to the output with a set
delay time. The output is not activated if the input is set to 0 again before the delay time has elapsed.
The error output is inactive since the function block sets no errors.
The maximum switch-on delay is 6 000 x 100 ms (10 minutes).
