Implemented below code to communicate python program with Modbus RTU protocol. However trying to read/write data to/from the python program, ModPoll software throws first timeout error & then "Insufficient byte received"
Kindly request to suggest the correct code to communicate with ModPoll.
enter code here
from pymodbus.client.sync import ModbusSerialClient
client = ModbusSerialClient(method="rtu", port="COM1", stopbits=1, bytesize=8, parity='N', baudrate=9600, timeout=200)
print(client.connect())
# result = client.read_holding_registers(102, 1, unit=1)
# print(result.registers)
client.write_register(1, 45, unit=1)
client.write_register(2, 45, unit=1)
client.write_register(3, 45, unit=1)
client.write_register(4, 45, unit=1)
client.write_register(5, 45, unit=1)
