CAN open safety on safety-related system-on-chip

Although the traditional task of communication protocols is the transmission of data, this is actually not completely sufficient if it is used in safety sectors. Therefore, it must be enhanced. In order to detect and overcome failures in systems, risk analysis and failure measurement must be taken into account in each safety-related system. This paper describes the advantages of having a safety-related system-on-chip with on-chip diagnostics in order to develop a safe transmission protocol. Here the concept of a CANopen Safety protocol stack on top of a safety-related system-on-chip that yields reliability to the complete product is presented.
