Ctup C1

CtDn C2
|--||-------[DNCtr]
[UpCtr] and [DnCtr] functions are available from the special function menu ----[Fn]

Thanks for your reply.
but can I not then use one counter eg:C1 as reversible up/down counter.
My program is as follow:
CtUp C1
|--||---( Upctr)
CtDn C1
|--||---( Dnctr)
so that I can use ctup and ctDn to count up/down of Counter C1?
how do I compare the counter value with some value say '4'?
ie: how do I know that the counter has counted 4 which is not the set value
Thanks

Sorry, my typo error. Yes, I meant that both functions operates on counter C1 so your circuit is correct.
If you use a TBASIC custom function, you can easily check the value of the counter:
IF CTRPV[1] = 4 THEN
...
ELSE
...
ENDIF
