Hello… I am trying to connect TRB145 to a energy meter to read the data through modbus communication. I am getting below data when I tried to query through Modbus. How to convert this data to Decimal?
The actual value of that register is 198.3 Voltage.

Response:
Unit ID:1, Function code:3, Data count:20,
Data:
1:[2.413316e-41] 2:[ 1.076168e+08] 3:[ 1.076168e+08] 4:[ 1.074790e+08] 5:[ 0.000000e+00]
Hello,
Could you clarify what data type you are selecting when querying data from the energy meter registers? Additionally, could you confirm if the function and data type are correctly selected according to the energy meter’s data sheet?
For testing purposes, have you tried selecting other data types to see if the response aligns with the expected values?
Best regards,
I used modbus poll software and queried the meter and i am getting proper data there. Attached the configuration used to read the data. Also attached meter register mapping. The meter support 2 data type Integer and floating… I am getting proper data on TRB145 if I try Integer data type but we need to use Floating type because Integer type need some conversion using CT ratio. Floating is directly giving all the values.
