I am using the HMI to collect grid information like voltages, currents, power, energy import, and export.

I need to know how to get the grid voltage values for both L-L and L-N. As a case to copy, I got the program from one of my customers’ HMIs, and the installer used the register address of 3x800 for L1-L2 voltages. I need to know where these 3x 800 register values are referred from?

The read device is the controller ECPV.

Any support/guidance will be appreciated.

Hi @mohsin160,

The device seems to have a built-in Modbus TCP server and the vendor provides a mapping table that you can reference on their website. For clarification on the 3x800 register (30800), I would recommend that you contact the controller vendor as I don’t see this register within their documentation.
