摘要
介绍一种PLC控制系统的多参数设定装置,其仅需PLC的3个输入点和3个输出点。PLC通过一个模拟的同步串行接口与 显示电路连接,显示PLC内部参数,并可用输入按钮对参数加以调整。该多参数设定装置简单、成本低廉,对小型PLC控制系统具有 积极意义。
A multi-parameter setting device of PLC control system is introduced. For this purpose, only three of inputs and three of output are needed. Through an emulated synchronous serial interface, PLC is connected with the dispky circuit for dispkying internal parameters. These parameters are adjusted by using input pushbutton.This multi-parameter setting device features simple and low cost, it offers significance to small sized PLC control systems.
