基于VB的PLC工业自动化控制系统的研究与实现

Research and implementation of PLC industry automation control system based on VB

在工业控制领域中,PLC作为一种稳定可靠的控制器得到了广泛的应用.由于其数据计算处理和管理能力较弱,不能给用户提供良好的界面,故提出运用VB开发程序实现PLC与计算机之间通信的方法,使系统达到既能及时地采集、存储数据,又可处理和使用好数据的功能.

In the industry control domain, PLC, one kind of stable reliable controllers is widely applied. But it also has its own limitations, namely data computation processing and the management ability are weak, and cannot provide good interface to the user. This paper presents a way using VB program to communicate between PLC and the computer. The system could gather, store and process data.
