Hello.

I am trying to control one signal between two times. Max state is easy to control with TON timer but not sure how to control it on min state.

Example:

Need to control active state of IN1.

If IN1 is active less then 2sec (min) and more then 9sec(max) I get OUT1 in logical 1.

Any suggestions?

Thanks.
