Build an *STM32 Modbus TCP Server* using the LWIP networking library and learn how to receive, parse, and respond to Modbus TCP requests over Ethernet.

In this tutorial, we start a new STM32 Modbus TCP series and configure the *Ethernet peripheral, LWIP stack, and MPU* using STM32CubeMX. We use the Nucleo H755 board with a static IP address and create a basic TCP server listening on the standard Modbus TCP port 502.
