I need to change the preset value for a counter in VMemory and not use the Kconstant. I have assigned the preset value of T1 -the KXXf value to V2001. This value is displayed in the status screen while in monitor mode with the PLC. This value is changing with the C-More panel as well as the data change function in DirectSoft, but the timer will not stop at the preset. Is there another parameter that needs to be set? RogerR

Are you discussing a counter or a timer? You say 'counter ' then refer to 't1 ', a timer.
In general, the accumulated value of a timer does not stop just because it reaches the preset. All it does is turn on its completion bit, named the same as the timer.
Use the turn on of the bit to perform any action you wish.

Thanks for the response.
Looked at the completion bit on the timer and found the issue was that the timer reset was cascaded with a second timer with a constant value that did not change as with the first time.
This let the first timer accumulate until the second timer constant value was attained before reseting.
Thanks again.
