Modbus communication error via Mapper

[p_xatzi]

Hi,

I have a Modbus RTU Power Meter (Delta DPM C520).

I have set physical communication correctly but I cannot implement communication via Mapper.

I have tried all sort of combinations for profile but result is still 0.00 for all values.

I have also restarted the device.

The device is a Reactor V3 with firmware Version: 20200720.

Can you please help?

I attach some files and a part of the profile that should work.

Thanks in advance
