远程I/O系统与DCS通讯的实现

Realizing the communication between the remote I/O system and DCS

远程I/O系统是一种新型的控制系统 ,近几年来发展迅速 ,应用量越来越大 ,技术上有一定的先进性。文中简要介绍了远程I/O的发展历史和技术特点 ,通过对德国p +f公司RPI和IS -RPI的具体分析 ,旨在使读者对远程I/O接口的技术特点有一个清晰的认识和了解 ,最后对p +f远程I/O接口与典型的DCS系统的通讯方式作了较详细的介绍。

The remote I/O system is a novel control system .The development history and technical characteristics about the remote I/O were introduced simply in this paper.By particularly analyzing RPI and IS-RPI from 'P+F' corporation Germany, the technical characteristics of the remote I/O interface were illuminated precisely. Finally, this paper introduced carefully communication ways between 'P+F' remote I/O interface and typical DCS systems.
