Abstract This paper introduces a embedded networking field controller with high performance ARM9-S3C2440 chip as central controller. The acquisition board is enhanced high speed singlechip controller based on RS422 bus used in C/S structure.The controller software in the host computer takes embedded Linux operating system as the platform, which is developed by the latest embedded GUI-based miniStudio development system.The controller is able to collect,display and save common signals in the industrial site and can remote access controllers via Ethernet.
