PLC与单片机之间的串行通信及应用

Serial communication between PLC and MCU and its application

在工业自动化控制领域,较为重要的内容就是PLC和单元机之间的远距离控制,并且在自控系统设计过程中,经常遇到的难题就是PLC和单片机之间远距离通信,基于PLC和单片机两者优势充分发挥的基础上,能够确保PLC和单片机之间串行通信的良好实现。本文基于实际情况的基础上,通过对现阶段较为常见且应用较为广泛的单片机进行分析探讨。

in the field of industrial automation control,the more important content is the long-distance control between PLC and unit computer,and in the design process of automatic control system,the problem often encountered is the long-distance communication between PLC and single-chip microcomputer. Based on the full play of the advantages of PLC and single-chip microcomputer,it can ensure the good realization of serial communication between PLC and single-chip microcomputer. Based on the actual situation,this paper analyzes and discusses the common and widely used single chip microcomputer at this stage.
