[M467] Using LwIP to Implement Modbus TCP

• Application: This example code uses the LwIP library to implement the Modbus TCP function for industrial network application. User can control the status of M467 through an industrial network server by the Modbus TCP protocol.
• BSP Version: M460 Series BSP CMSIS V3.00.001
• Hardware: NuMaker-M467HJ V1.0
  

This example code uses the LwIP library to implement the Modbus TCP function for industrial network application. User can control the status of the M467 series microcontroller (MCU) through an industrial network server by the Modbus TCP protocol.

Modbus is an industrial communication protocol used for system monitoring and remote data collection in automatic systems. Common communication interfaces for Modbus include RS-232, RS-485, Ethernet, etc. It defines a set of commands and data formats that allow a master device to send instructions to slave devices, which can be used for reading and writing slave data.

Modbus is also used for monitoring and controlling various devices like programmable logic controllers (PLCs), sensors, valves, servos, human-machine interfaces (HMIs), etc. It provides a standardized communication method for devices from different vendors to communicate with each other. Modbus protocol enhance the efficiency and reliability of automatic systems.
