 1756-IF8/ABPLC模块

    在工业生产中，人们常常面临着数据采集与管理。作为工厂自动化的三大支柱可编程控制器PLC（Programmable Logic Controller），由于其安全可靠，广泛的用于数据采集与控制。生产过程中，要监视PLC内部的数据与运行状况，选用市场上的人机界面或组态软件，虽然功能丰富，但大都价格昂贵，在一些中小规模的生产场合，人们希望能自己用高级语言开发一个简易实用的通信程序。微软公司推出的Visual Basic 6.0，开发串行通信程序时，有两种方法，一种是用Windows API函数，另一种是用VB支持的通信控件MSCOMM.OCX。利用Windows API函数是通过调用读写等函数来操作串口。两种比较，使用MSCOMM.OCX控件编程方便，具有更完善的发送和接收功能。这里采用了MSCOMM.OCX控件。
