Modbus Error: [Input/Output] [WinError 10054] An existing connection was forcibly closed by the remote host

[Mininggamer]

Python: 3.10
pymodbus: 3.1.3 (I still meet this issus when using version 2.5.3 with pymodbus.client.sync.ModbusTcpClient )
I'm trying to write data to my PLC through modbus tcp/ip. Here is my code:

from pymodbus.client import ModbusTcpClient

client = ModbusTcpClient("192.168.0.1", port = 502)
client.connect()

client.write_registers(0, 1)

It doesn't output anything. and my PLC doesn't receive any data.
If i use print(client.write_registers(0, 1)) instead of client.write_registers(0, 1) the terminal show

Modbus Error: [Input/Output] [WinError 10054] An existing connection was forcibly closed by the remote host

As it writes your device closes the connection. Are you sure your device allows writing to address 0 ?

Closing issue, since it is not a problem with the library.
