摘要
随着PLC应用的日益广泛,利用计算机和PLC开发出个性化的监控系统,已经成为广大用户的迫切需要。用高级语言编写的通信软件适用于一些小规模的、比较简单的控制系统,这样不但可以节约投资,而且实践表明系统稳定,通信简单。文章根据实际工程,探讨基于VB平台下PLC与上位机的串行通信设计和实现。
With the increasing application of PLC, using PC and PLC to develop an individual supervision system has become an urgent demand of the user. The communication software written by a high-level language is fit for some small scales and simple control system, and thus not only retrench investment, but also reveale stabilization and convenient communication in practice. According to actual engineering, the paper discussed the design and realizations of serial communication between PLC and PC by Using VB.
