Carlo Gavazzi EM330 - oyvindnordbo - 13.05.2022
I'm trying to implement an energy meter from Carlo Gavazzi EM 330, the registers I should read are 300041, but when I try with "read test" on the LM5, the highest register I can read is 65535.
Attached is the script I made and the modbus register for the meter.

Remove 3 from the beginning and subtract 1 so 300041 becomes 40 and so on.

Hi,
in attach my profile for EM-340 I am using. As I remember - they are totally the same, for my device I cannot change voltage and current transformation coefficient. Also exist models counting consumed and produced energy, I have only consumed power counting..
Profile is working except reactive power - should be checked..
