Do more timer

[azeotrope]

I have noticed my timers are running 2x too fast. A tmr set for 30 sec runs 15 sec. What can cause this?

Thanks

Make sure you are only using a timer resource once, e.g. T0 - you should only have one timer instruction using T0.  Look in your Cross Reference view, or float your cursor over the timer in question and let the Cross Reference pop-up and see where the timer structure is being used as an OUTPUT or INPUT/OUTPUT (in/out).

You would also be seeing a Program Check Warning being logged at download time for duplicate timer structures being used (you can also run Program Check via the Online Toolbar or via the menu, PLC->Program Check).

Yeah that was it, should have seen that. Thanks
