Greetings, Programming a Logo with Comfortsoft V7 I see no DF instruction for differential or edge detection.

I have resorted to using AND and NAND function blocks that have + and - edge detection respectively. AM I missing something? :unsure:
 
Thanks IANT. As far as I can tell the edge triggered wiping relay is useful for positive going edges only.

Programming wih Logo is very intuitive however it seems to be missing this one instruction element.
 
the edge trigger is in the Timer area
you will find the one you want there
