rtu-over-tcp connect fail

[劉姿汶]

I am trying to read and write data on RTU over Modbus TCP with python. But it prints false, this means client.connect() has failed.

from pymodbus.client import ModbusTcpClient 

from pymodbus.transaction import ModbusRtuFramer as ModbusFramer 

client = ModbusTcpClient("192.168.1.232", port=502, framer=ModbusFramer) 

success = client.connect() 

print(success)
