I am using pymodbus. i have to establish connection and read some register values. I can connect but the devices aren't responding back to any query . I'm pretty sure register values are fine.I can ping the device so connectivity isn't the issue.
I tried reading different values for register, this is the error message: Error reading holding registers: Modbus error: [Input/Output] Modbus Error:[invalid Message] No response received, expected at least 8 bytes (0 received).
