[HELP] bytes_modbus_uplink_converter - convert - 84 - Exception Response(131, 3, IllegalAddress)

[knityanand]

Describe the issue I am trying to get the data from energy meters with the following data config

and I am getting a NULL value and then the exception mentioned below bytes_modbus_uplink_converter - convert - 84 - Exception Response(131, 3, IllegalAddress)

I get it for both the float and swapped float. I guess, I am doing something wrong in the modbus.json. Would appreciate some help Also what changes need to be done for a swapped float

Also, please find attached the values being fetched from modbus tester for the energy meter with float values

Connector name (If you need help with some connector/converter): modbus.json

Error traceback (If it was raised): error.log

Versions (please complete the following information):

@DuXiaoChuang Thanks so much.. This worked. Wondering why I have to add / subtract 1 from the address which works in modbus tester or modscan64.
