摘要：

为了完成基于CAN协议的可编程控制器与KingView的通讯,以高性能AVR单片机为处理器设计实现了CAN总线协议与MEWTOCOL-COM协议转换的数据适配卡。PC机通过CAN总线控制PLC,并将PLC采集到的状态信息送回PC上的组态王软件处理,完成状态监测。实验结果表明,该系统具有良好的实时性、可靠性和实用性。

Abstract: In order to realize the communication between PLC and Kingview with CAN bus, a data adopter card was developed to realize the protocol transform between CAN bus and MEWTOCOL-COM by the use of high-proformance AVR mcu.The PC controls PLC through CAN bus, and sends the status messages collected by PLC to the Kingview software to process and complete state monitoring.Experimental results show that this system has features such as good real-time, reliability, practicability and so on.

Keywords: CAN Bus; MEWTOCOL-COM protocol; PLC; Kingview
