| 摘 要： | CANopen作为CAN总线的一种很有影响力的应用层协议,在工厂自动化系统中得到广泛应用。软PLC是一种基于PC机的新兴自动控制技术,不仅能够实现硬PLC的所有功能,而且遵循IEC61131-3编程标准,为用户提供了更多的开放性。本文应用P87C591单片机开发了基于CANopen协议的I/O从站,通过上位机CAN卡构建了基于CoDeSys软PLC的分布式I/O控制系统,验证了系统信息传递的可靠性、准确性和实时性,很好地满足了印刷机无轴传动控制系统的要求。

| Abstract: | CANopen, as a well- known application protocol of CANbus, has been widely applied in factory various automation system. Soft PLC, which is a new automation control technology based on PC, implements all functions of the traditional hard PLC, follows IEC61131- 3 programming standard, and provides more open features to the customers. This paper describes the development of CANopen compliant I/O slave based on P87C591 microprocessor and its application in a distributed I/O control system based on CoDeSys Soft PLC through CAN card in PC. Finally, the reliability, veracity and real time feature of data communication are verified by testing experiment, and CANopen compliant I/O slave well meets the requirement of the shaftless control system of printing machine. |
