In order to meet the needs of applications requiring a certification for the safety of operation, ISIT offers the only "ready-to-use" CANopen stack available on the market with Safety extension, in accordance with the EN 50325-5 standard, together with its certification pack. This solution enables the rapid integration of this software component into a product subject to the requirements of IEC 61508 up to SIL 3 or DO-178C DAL B, while enjoying a ROI incomparable with a proprietary solution.
CANopen
The CAN bus, initiated by Bosch in 1991 and standardized in 1993 (ISO 11898), has experienced uninterrupted growth since its inception, well beyond the scope of the automotive. It has proven by its robustness, reliability, simplicity and the low cost associated with its implementation that it was the ideal protocol for the control of real-time networks, while Ethernet could be dedicated to applications requiring a larger bandwidth for the data. In 2016, 1.5 billion CAN nodes were deployed (CiA source). The CANopen application layer provides flexible and powerful mechanisms for configuring, diagnosing and monitoring the network, with the definition of profiles making it possible to design interoperable products. The design of a system is then greatly simplified.
Safety applications, for which safety is a major issue, need to meet stringent standards and must be certified by an independent organization. This process, which generates significant costs, must be taken into account from the beginning of the project and requires strong expertise.

About the product :
The ISIT CANopen Safety Certifiable Stack (ISIT_COSAFE_LC) meets the needs of these applications and allows developers to use the advantages of the CANopen protocol while benefiting from the necessary elements for the certification of the product with an approved organization: documentary set, unit and integration testing plans, test reports…
Delivered as source C code, independent of the CPU/OS platform, ISIT_COSAFE_LC can also operate without an operating system (NullOS).
Services
Upon request, ISIT can adapt the stack onto a specific system and perform the necessary test sets to approach the certification process with confidence.
