i have a software for some comperssor , and i want to turn it on after 5 seconds from getting demand for runnig , and trun it off after 5 seconds from getting demand for stop.
the delay of run works rightly , but the delay of stop does not work

What I have tried:

IF COMPRESSOR_IN = TRUE THEN
	TON_1(TRUE, t#5s);
	COMPRESSOR_OUT := TON_1.Q;	
ELSIF COMPRESSOR_IN = FALSE THEN
	TON_2(FALSE, t#5s);
	COMPRESSOR_OUT := TON_2.Q;
	TON_1(FALSE, t#5s);
END_IF;

what is TON_1 and TON_2?

they are a ready block for making delay . thier inputs : bool and time . their outputs are bool and time too .

Delay of stop does not work - this means, something is wrong in TON_2 function. You need to provide more information.

How many different values can "COMPRESSOR_IN" have? (Why "elseif" if it's a bool?)

Why is TON_2 never "turned on"?

yes , COMPRESSOR_IN is a bool .
