CANopen Safety is a protocol extension to the proven CANopen Standard (EN50325-4). At the physical layer and the lowest level of communication according to the OSI model, the internationally standardised CAN bus (ISO 11898-1/2) is used.

CANopen unburdens the developer from dealing with CAN hardware-specific details such as bit timing and acceptance filtering. It provides standardized communication objects (COB) for time-critical processes, configuration as well as network management data.

CANopen Safety 作为欧洲标准 (EN 50325-5) 发布。 这意味着可以通过满足 SIL3 应用要求的 CAN 网络传输数据。 这种面向安全的数据传输可以与现有的 CANopen 数据传输并行进行。 CODESYS CANopen Safety 支持符合 SIL2 的安全要求。

CANopen is a communication protocol stack and device profile specification for embedded systems used in automation. In terms of the OSI model, CANopen implements the layers …

它采用ANSI-C开发标准，独立于硬件（除了CAN驱动），促进了主设备和从设备的快速开发，包括SDO、PDO、NMT（网络管理）、LSS (层设置服务) 和 安全 通信消息 (SRDO) 等必要服 …

CANopen Safety sensor sends output with SRDO. SRDO stands for Safety-relevant data object. It is the only mechanism to transport safe data in an CANopen network. An SRDO shall be transmitted cyclically. The cyclic transmission is monitored. An SRDO may be transmitted event-driven in addition to the cyclic transmission, if required.

ISIT offers a software CANopen protocol stack (ISIT_COSAFE) compliant with the CiA-301 and CiA-304 standard. Developed in ANSI-C and independent of the hardware (except for CAN driver), it eases the rapid development of master and slave devices, including the necessary services like SDO, PDO, NMT (network management), LSS (layer setting ...

CANopen networks enable transfer of safety-oriented information. Safety functions (e.g. Emergency OFF, Two-handed operation) can be integrated into a CANopen network.

不 CANopen 安全接口一起使用了。迄今为止 TR 已推出基于以太网的 PROFINET / Ethernet/IP、FSoE (� Powerlink open SAFETY。 不这些接口丌同,CANopen Safety 根据“白色通道原理”工作,即在对整个应用程序的 评估中,整个信号路径必须证明其可

CANopen Safety是第一个获得BIA许可的CAN解决方案。 CAN in Automation GmbH（CiA）委托SYS TEC开发CANopen Safety Chip CSC01。 设计的芯片能在SIL3的安全级别上安全应用。 该芯片已经按照IEC 61508标准被进行测试且被TÜV Rheinland预鉴定。 CSC01是基于RENESAS（瑞萨）16位的微控制器，它包含符合CiA标准304的CANopen协议，且能被集成到客户自己的安全设备上。 回顾CANopen的历史，1986年2月，Robert Bosch公司在SAE（汽车 工程协会）大会 …
