Energy Electric Add-On Instructions Appendix C

To calculate the electric demand, a MUL instruction converts the Set_Demand_Interval minutes to milliseconds for the
preset used by the Demand_Interval_PLC_Timer and Demand Interval_Exceeded Timer. Once the Cmd_End
of_Demand_Interval is set, the Val_Total_kWh is compared to the previous interval's Val_Total_kWh, and the
Val_Demand_Electric is calculated.
