CANopen Safety Chip CSC01 / CSC02
|
The CSC consortium hosted by the CiA GmbH (CAN in Automation) commissioned SYS
TEC with the development of the CSC01 as well as CSC02 CANopen safety chip.
Both versions of the CANopen safety chip are designed
for use in safety-relevant applications up to SIL3 (Safety Integraty Level).
The CSC01 with its permanent firmware is certified by TÜV Rheinland (Report
No: 968/EL 215.01/04 of July 30, 2004). The CSC01 is based on a 16-bit Renesas
M16C (M206NAFGTFP) microcontroller.
The CSC02 chip is certified by the
TÜV Rheinland Group too. The report of the certification test is released under
the number 968/EL 215.02/09 on the date 2009-10-23. The CSC02 is certified for
safety-relevant applications up to Safety Integrity Level (SIL) 3, according
to IEC 61508, and Safety Category 4, according to EN 954-1.
Both
includes the CANopen Safety Protocol in
accordance with CiA specification DS 304 and allows a fast integration by the
user into its own safety devices.
Customer-specific software components can be loaded later into the CANopen safety chip
flash. Accordingly, the CANopen safety chip can be used in a number of applications (for
example, emergency stop buttons, safety relays, light curtains or generally as
safe CANopen bus interfaces, etc.).
To achieve SIL3 certification for single-processor solutions the
international IEC 61508 standard requires a diagnostic coverage level of >99
% within a defined safety cycle time. This high degree of diagnostic coverage
requires extensive error detection procedures such as diagnoses of the flash,
RAM, CPU register and Op-code.

Scope of Use and Start-up of the CANopen Safety Chip
The CANopen safety chip
CSC01 and CSC02 are sold by CiA GmbH. SYS TEC offers Rapid
Development Kits for the CANopen Safety Chip providing easy start-up of the
CSC01 and CSC02. With its use in safety-relevant systems, there is a significant reduction
of development time and certification costs. Time-to-market is reduced
considerably.
The CANopen Safety Chip can provide complete control and monitoring in simple, fail-safe
sensor-actuator systems. In complex devices (e.g. light curtains, drives) it
acts as a communications interfaces. A generic function and data interface
(callgate) represents the interface to the user-application. Consequently, the
user can access the CANopen functionality, the safety-relevant data and the
object directory. The user-oriented programmability of the CSC01 and CSC02 opens up
flexible utilization in different areas. The CANopen Safety Chip can be used within a CANopen
networks in combination with secured and unsecured devices.
