Omron PLC integral calculation

[tingxing 1]

Could anyone tell me how to do integral calculation in Omron PLC? I get power (in fact, current) data, and I want to calculate power vs time integration. Thanks in advance. Xing Edited 14 Oct 2013 by tingxing

On every cycle execute something like this; ErrorValue = CurrentValue - SetPoint IntegralSum = IntegralSum + ErrorValue * CycleTimeValue (A264 for CJ1) Then use IntegralSum as a scalar as it will get pretty big
