Giving a momentary pulse

Raffy Posts: 209 Rating: (2)	Hi, Please help me guys, what would be the smallest program or code that we could use to produce a momentary pulse...say when I press this button(actual real button, about 5 seconds)..the Digital input of the PLC would sense it but would only pass a pulse--a momentary pulse say.... I know a positive edge trigger can do this using lad...but how about in SCL or any program that will not utilize a positive edge trigger... Can you suggest something?? Thanks Best regards, Raffy
