Certainly! Modbus is a widely used communication protocol in industrial automation and is commonly implemented over TCP/IP for remote communication between devices. In Python, you can use the pymodbus library to easily implement Modbus TCP communication. This tutorial will guide you through the installation process, basic usage, and provide a code example.
You can install the pymodbus library using the following pip command:
Let's start by creating a simple Modbus TCP server using the pymodbus library. In this example, we'll create a server that listens on port 502 (the default Modbus port) and registers some holding registers.
Save this code in a file, let's say modbus_server.py, and run it. This will start a Modbus TCP server on your localhost.
Now, let's create a Modbus TCP client to read and write data from/to the server. In this example, we'll connect to the localhost server and read the values from holding registers.
Save this code in another file, let's say modbus_client.py, and run it. This client code connects to the Modbus TCP server, reads the values from holding registers, writes new values, and then closes the connection.
This tutorial provided a basic example of using the pymodbus library to create a Modbus TCP server and client in Python. Modbus has many other functionalities, and you can explore the documentation for more advanced features and configurations: pymodbus Documentation.
Remember to adapt the code according to your specific use case and Modbus device requirements.
