摘要
以Foxboro公司的I/A′s系统为例,讨论在分散控制系统中实现通信的3种方法:利用专门硬件、利用专业通信软件及自行开发通信软件。着重介绍自行开发通信软件的一些方法及其主要编程函数。通过几种实现方法优缺点的比较,为用户在选择通信方式时提供参考。
The communication between DCS, PLC and PC is very important in a DCS project. Foxboro's I/A series system is one of the main
DCS systems used in China. This paper majors in the three main communication methods between Foxboro'sI/A's system and other DCSs,PLCs
or PCs, they are: to use the hardware to perform communication, to use the professional software to fulfill communication and user-developed
program to achieve communication. This paper emphatically briefs some methods of communication software developed by the user and its
main programmable functions. Through the strong and weak points comparisons between several lealized methods, the reference is provided
for users to select the appropriate communication method.
