摘要
以 OMRON CPM1 A型 PLC为例 ,介绍了如何用 Visual Basic语言实现计算机与PLC的通讯 .该方案具有硬件简单、使用灵活的特点 .该通讯系统对于用计算机控制 PLC实现集中监控提供了可靠的手段 ;同时为利用计算机进一步开发基于
Taking OMRON CPM1A PLC as example, design of communication between computer and PLC is introduced by using Visual Basic programming in this paper. This solution has simple hardware structure,and it is easy to use. The communication provides a reliable means for the PLC network controlled with computer,so that the centralized monitoring is implemented. At the same time, a reliable way to acquire the diagnosis information for developing the fault diagnosis system based on PLC information by means of computer is offered.
