摘要:
首先介绍了CAN总线技术的发展概况及基本原理。在CAN总线技术广泛应用的背景下,为了降低三菱FX系列PLC使用CAN总线组网的成本,提出一种基于PIC18F25微控制器的通信转换装置。该转换装置实现了CAN通信协议与三菱PLC专用协议的转换,采用三个拨码开关设置CAN通信参数和串行通信参数,操作人员可根据实际情况灵活调整装置通信相关的参数。相较于三菱公司为PLC适配的CAN总线模块,该装置成本低廉、操作简单且通用性强,可以使三菱FX系列所有型号的PLC通过自带的通用串口接入CAN总线网络。
Abstract:
Firstly, the development and basic principle of CAN bus technology are introduced. Under the background of wide application of CAN bus technology, in order to reduce the cost of Mitsubishi FX series PLC networking based on CAN bus, proposing a communication conversion device based on PIC18F25 microcontroller. The device realizes the conversion between CAN communication protocol and Mitsubishi PLC proprietary protocol. Three dial switches are used to set CAN communication parameters and serial communication parameters. The operator can flexibly adjust the communication parameters of the device according to the actual situation. Compared with the CAN bus module produced by Mitsubishi Corporation, the device has the advantages of lower cost, more simple operation and stronger versatility. It can make all types of FX PLC connect to CAN bus network through its own universal serial port.
