Signal is valid only a defined period of time

 

Hi,

I want to programm, that my relative max/min is only be valid for e.g. 11 hours.

What is the shortest way to wrote it?

Lot's of thanks!

 

Is it so difficult?

I thought about the following opinion:

I add to the actual time the number of hours, if the relativ max/min is reached.

Is there an easier way?
