### What happened? Clean Xubuntu install. Installed Python 3.11.6 Setup PLC4Py from source using the following source code: ``` import asyncio from plc4py.PlcDriverManager import PlcDriverManager connection_string = "modbus://127.0.0.1:5020" driver_manager = PlcDriverManager() async def communicate_with_plc(): async with driver_manager.connection(connection_string) as connection: with connection.read_request_builder() as builder: builder.add_item("Random Tag", "4x00001[10]") request = builder.build() future = connection.execute(request) await future response = future.result() asyncio.run(communicate_with_plc()) ``` result = PlcResponse(response_code=<PlcResponseCode.NOT_CONNECTED: 12>) Attached Wireshark Capture: [plc4py_modbuspal_port5020.zip](https://github.com/apache/plc4x/files/14757528/plc4py_modbuspal_port5020.zip) [PLC4Py_ModpusPal_Port5020.txt](https://github.com/apache/plc4x/files/14757553/PLC4Py_ModpusPal_Port5020.txt) ### Version v0.12.0 ### Programming Languages - [ ] plc4j - [ ] plc4go - [ ] plc4c - [ ] plc4net ### Protocols - [ ] AB-Ethernet - [ ] ADS /AMS - [ ] BACnet/IP - [ ] CANopen - [ ] DeltaV - [ ] DF1 - [ ] EtherNet/IP - [ ] Firmata - [ ] KNXnet/IP - [X] Modbus - [ ] OPC-UA - [ ] S7 -- This is an automated message from the Apache Git Service.
