IVE GOT A QUESTION FOR PROGRAMMING IN FBD

I MUST HAVE A COUNTER(s-cud)

that count's up to 15 and if he's 15 then he must "set" the exit(q) to 0and if he's under 15 the q must be 1

how must i program this?

Pieteke,

if you go to the on-line help of Step 7 and look up the down counter, teh up counter and the up/down counter, you'll find exactly the instruction you need. One hint: trying to do it with an up counter would be like driving from Brussels to Antwerp over Madrid. Nobody tells you not to do it, but it isn't efficient att all.

Kind regards,
