摘要
以三菱FX2N系列可编程控制器(PLC)为例,介绍一种基于PLC的实时监控系统。该系统利用VB与PLC的串口通信,实现了上位机对下位机的实时数据采集、实时监测和控制分析等功能。实际应用表明:该实时监控系统运行可靠,操作方便、简单实用,并对由其他类型的PLC和上位机组成的监控系统的构建具有一定的参考价值。
With MITSUBISH1 FX2N series PLC for example, a real-time monitoring system based on PLC is introduced. By the serial communication between VB and PLC, this system has realized the execution of the principal computer acquiring data from the subordinate computer, real-time monitoring, control analyses, etc. The application shows that the system is easy to perform and has the reliable functions, simple practical, and provides certain value with other type of PLC system.
