中文摘要: 介绍了一种通过现场总线组成的CPM2A型PLC工业应用网络的设计方法,并给出了上位机通讯程序.CPM2A自带RS232接口,通过Hostlink协议能够实现一对一的上位机通讯.采用RS232 CAN模块将RS232接口转换成CAN接口,通过上位机软件协议的转换方法组成PC-PLC网络系统.

中文关键词: CAN总线 PLC网络上位机软件

Abstract:A design of a CPM2A-PLC netwok based on CAN-BUS communication protocol is introduced, and computer communication programs are designed.The RS232 port built in the CPM2A PLC supports host link communication protocol, which can only communicate with super computer by one to one link.The RS232 port is converted to CAN port by RS232 CAN module in this paper, and PC-PLC network is built using protocol conversion by software in super computer.

keywords: CAN bus PLC network super computer software
