Modbus TCP Repository

Latest release: 1.0.1rc0
Maintainer: XMOS
Description: Modbus TCP (Slave) component

Firmware overview

This is a Modbus TCP Server component (A Modbus Slave). Modbus protocol specification and messaging implementation guide can be found here:

The Modbus TCP Server component accepts data from the TCP layers and processes them for Modbus commands. If the received TCP data is a Modbus command, the component requests data from/to the user application. The request (Modbus Command) is usually to read/write values from/to registers, coils, etc... After this, the component forms the required Modbus response, sends it back to the TCP client (Modbus Master) and waits for next Modbus command.
