Modbus Event Connect

Welcome to Modbus Event Connect – a user-friendly, event-driven Python library designed to simplify the configuration of Modbus devices and interact with them in an event-driven way. Whether you're connecting via TCP or Unabto, Modbus Event Connect has got you covered.

Features

• Event-Driven Architecture: React to changes and events in real-time.
• Easy Configuration: Intuitive setup for Modbus devices.
• Flexible Connectivity: Supports connection through TCP or Unabto.
• User-Friendly: Handles the interaction; you just define the Modbus register items.

Getting Started

1. Installation: Install the library using pip.

   pip install modbus-event-connect

2. Basic Usage: Define your DataPointKeys to a Modbus device with minimal code.

   from collections.abc import Callable
   from src.modbus_event_connect import *
   
   class MyDatapointKey(ModbusDatapointKey):
       MAJOR_VERSION = "major_version"
       
   class MySetpointKey(ModbusSetpointKey):
       MY_SETPOINT = "my_setpoint"
   
   class MyModbusDevice(ModbusDeviceBase):
       def __init__(self, device_info: ModbusDeviceInfo):
           super().__init__(device_info)
   
           self._attr_manufacturer="<manufacturer>"
           self._attr_model_name="<model_name>"
           self._attr_datapoints = [
               ModbusDatapoint(key=MyDatapointKey.MAJOR_VERSION, read_address=1, divider=1, signed=True),
           ]
           self._attr_setpoints = [
               ModbusSetpoint(key=MySetpointKey.MY_SETPOINT, read_address=1, write_address=1 ,divider=1, min=1, max=10, signed=True),
           ]
   
   class MyModbusDeviceAdapter(ModbusDeviceAdapter):
   
       def _translate_to_model(self, device_info: ModbusDeviceInfo) -> Callable[[ModbusDeviceInfo], ModbusDevice]|None: 
           return MyModbusDevice
   
   class MyModbusTCPEventConnect(ModbusTCPEventConnect):
       _attr_adapter = MyModbusDeviceAdapter()
