3 Phase Kwh counter under Modbus Analog IN

Domenik Posts: 72 Rating: (1)	Hello, I need a help how to counter 3 Phase Volt+Amps under Modbus network, for a new ATS generator smart system. Before I made one small model with the Modbus 3 phase Energy meter and pulse Kw calculator, but about the all energy meter are only up to 100A, with the professional ATS can be used up to 3200A. In this way, when I resolve my problem with Analog IN, then I can use for more bigger ATS switch. My system setup. Logo 12/24Rce + external Modbus TCP 8 AI+8DI+8DO On Modbus the value range of the expansion module for Analog Inputs are 0-20.000 ( like 0-20ma range) NAI1: L1 Volt, NAI2:L2 Volt, NAI3:L3 Volt, NAI4:L1 Amp, NAI5:L2 Amp, NAI6: L3 Amp The 3 phase 4-20ma Volt transmitter 0-600V The 3 phase 4-20ma Ampere trasmitter 0-100A Right now I can full read the 3 phase L1+L2+L3 Amps and voltage, but I like now how to calculate the total Kwh for each Phase and the Total Amps of the 3 phase. If also how to calculate the Watts for each phase and total of the 3 phase. I found here some interesting project but are only for 1 Phase Kwh calculator and always with Pulse energy meter..
