应用于安全相关领域的CANopen Safety协议

CANopen协议是一种基于CAN（Controllor Area Network）总线的高层协议,在工业领域已有了极其广泛的应用。近年来,针对在安全相关领域的应用,CANopen协议加入了安全的特性,推出了基于CANopen协议的CANopen Safety协议。首先介绍了CANopen协议,在讨论了CAN和CANopen协议的失效机制的基础上,进而分析了CANopen Safety协议在安全相关方面的新特性。

CANopen Safety Protocol Based on Safety——related Application

CANopen is the higher-layer protocol of CAN,it has an extremely wide range of application.In recent years,research on the safety-related system gradually bacame the focus of industrial automation field,CANopen Safety protocol was intro-duced based on CANopen protocal.The concept of CANopen protocol and the basic failure mechanism of the CAN and CANopen protocol is introduced,the new security features based on CANopen Safety is also anylized.
