PLC－56B可编程序控制器模拟量I／O功能的实现

Implement the Function of Analog I/O on PLC-56B Programmable Controller

在工业控制场合，常常需要对多路模拟量信号进行检测，并且还要对多路模拟量信号进行控制。本文介绍了一种成功应用于ＰＬＣ－５６Ｂ可编程序控制器中，可对多路模拟量信号进行检测与控制的有效方法。

It's usually needs to be tested and controlled about the multi-way analogue signals on industry controlling. In this paper, a method that's applied in PLC-56B for testing and controlling multi-way analogue signals is introduced.
