SYS TEC services for safety-compliant industrial automation solutions
In various customer projects SYS TEC derived valuable experiences in the development of safety-relevant automation solutions. Projects, which are subject to certification, impose complex requirements on project management and documentation. A safety-relevant application development requires a clear specification, into some of which preliminary inspections are incorporated. Then the safety concept is built upon this specification, and must be confirmed and released by the certifying body (i.e. TÜV or BIA). Only then a successful implementation can be started.
At SYS TEC the complete range of hardware and software developments are done according to the well-proven V-model. The source code for software must be written in a structured and transparent fashion. Not every compiler satisfies the requirements of certification. Hardware components must be selected according to principles of reliability and have to be proven as well. Safety-compliant developments require a continuous and close interaction of project and certifying body. White-box and black-box tests are constant companions of a safety implementation.
SYS TEC has been successful in incorporating these stringent development requirements in its project management. Take advantage of this expertise for your market head start.
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 certifiedfor 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. |
