PLC与单片机之间的串行通信及应用

PLC系统可实现与单片机之间的串行通信,这一组合方式在工业自动化控制技术领域中非常常见且具有重要地位。当然,串行通信应用问题本身也是自动控制系统设计的重要难点。本文希望首先了解PLC与单片机相关理论概念与串行通信特点,然后对二者之间的串行通信技术应用流程进行深入研究分析。

The PLC system can realize the serial communication with the single chip microcomputer,this combination mode is very common in the field of industrial automation control technology and has an important position. Of course, the application of serial communication itself is an important difficulty in the design of automatic control system. This paper hopes to first understand the theoretical concept of PLC and single-chip microcomputer and the characteristics of serial communication, and then the application process of serial communication technology between them for in-depth research and analysis.
