Smartlogger Huawai

[gdimaria]

Hi, I can't read modbus register on this Smartlogger with TCP connection, device address: 0 (fixed).

I created the attached modbus profiles (40*** formart as in the pdf and ***),  mapped register with virtual objects, but I receive no data.

on the contrary, with Modbus Tool I can read everything.

Can you help me?

Thanks

Usually the starting number 4 indicates the function code so it should be ignored in the register address. What do you get when running Read test?

I can't run read test because I can't select device address 0.... it's starting from 1

There is no such thing in modbus as addressee 0, try 254 or 255

you are right, sorry....  the correct id is 50.

By the way, now I can read almost all register in the profile but KW value registers: they are both on 0 value.

if I run a read test they give me an int value.

Add "datatype": "uint32" to relevant profile entries. You should also add value_multiplier where applicable. But in this case bus_datatype should be a floating point value, not uint32.

ALL RIGHT! Thanks
