Gauss Posts: 10 Rating: (0)	Hello Pegia I think the correct answer is: if S=True then Q:=true; end if; if R=true then Q:=true; <=FALSE end if;

Gauss Posts: 10 Rating: (0)	Hello, Everything is fine and thanks. By the way I would like to some (many)SCL program to write (I am a begginer) and your topic have got good idea. Example: falling (rising) edge etc.

Still I'd like to show an easy way to make Set reset and rising edge detection: On := On OR SetCommand //Set On := On AND NOT ResetCommand //Reset OnEdge := On AND NOT LastOn; //Rising edge detection LastOn:= On; //Save On for next scan Good luck with SCL programming!

It is however, memory and time "expensive" for small applications/CPU. Here there is a set of then as V12 libary. Attachment BinaryBasicFBs.zip (389 Downloads)
