Parameters > Citect.ini File Parameters > Accumulator Parameters > [Accumulator]WatchTime


The time in seconds between each check of the accumulator trigger. You can set this parameter to a large value to conserve CPU and PLC communication time. If you set the WatchTime to a low value, CitectSCADA must poll the PLC more often for the trigger value, using CPU and PLC communication bandwidth.

Ensure that all time and period-based events in the project are a direct multiple of the WatchTime, otherwise they will not be checked.

Allowable Values: 1 to 36000 (seconds)

Default Value: 60
