Title: ABB energy Analyzer M4M30

Hello everyone,

I'm a new user in TIA Portal, and I'm currently facing an issue while trying to read values from an ABB M4M30 energy analyzer using Modbus. It seems like the Modbus registers are not readable. I need assistance in creating a program to read a single value from the M4M30 energy analyzer.

Additionally, I've noticed that the value I need is not in the typical Modbus register range (40001-49999). Can someone with experience in working with the ABB M4M30 guide me on how to adjust the readings to fit within the required range? Any sample code or step-by-step instructions would be greatly appreciated!

Thanks in advance for your help.
