Reading data from Modbus devices using Python

Hi

I am working with Simatic IoT2040 and want to read data from Modbus Energy Meter. I am running a python script on IoT that uses pymodbus. But, I could not fetch the data from energy meter and continues to get error. I have attached the code that I have used. Could you help me to find the solution?

Error:

Traceback (most recent call last):

     File "./modbus.py", line 20, in <module>

          print(result.registers)

AttributeError: 'ModbusIOException' object has no attribute 'registers'
