The EM6400 series power meters are digital power meters that offer comprehensive electrical instrumentation and load management facilities in a compact and rugged package.
This Repository contains the Python Script that can fetch these electrical data like voltage, current, power, energy consumption etc. from EM6400.
EM6400 sends out the data using Modbus RTU protocol and hence necessary libraries are been included which supports Modbus RTU mainly pymodbus.
- Install all the required libraries for execution of code.
- Command to include most important library
pip install pymodbus - EM6400 is declared as ModBus Client and hence edit the necessary parameters in the code line 16
client = ModbusClient(method ='rtu',<port used>,<stopbits>, <bytesize>, <parity>, <baudrate>)
- To read holding registers the below function is used, enter the parameters accordingly.
client.read_holding_registers(<register address>, <No of registers to read>, <slave unit id>)
- The parameters and their respective register addresses being read in the script:
- Current average - 43913
- Line to line average voltage - 43907
- Active power, total - 43903
- Forward active energy - 43961
Note : While entering the register address in the function intial digit 4 is not required as holding registers always has the address in the decimal form as 4xxxx
