Description:Modbus TCP Component - Server

Firmware Overview

This is a Modbus TCP Server library. Modbus protocol specification and messaging implementation guide can be found here:

http://www.modbus.org/specs.php

A Modbus client (e.g. on a PC) can send ‘requests’ to the Modbus Server running in an Xcore via TCP. The TCP layer accepts this data from the client and passes it over to the modbus_event_handler.

This frame is then processed by modbus_pkt_processing and a response is generated which is carried back to the client via TCP.

Demo Application

A demo application using the SImplyModbus client side software and an XC-2 Ethernet development board is included.

Documentation

See http://github.xcore.com/sc_modbus_tcp/ for design documentation and demo quick start guide.

To Do

  • A single thread variant that can process Modbus requests in parallel to TCP communications.
