Description

The Wendelstein 7-X safety control system is one of the main central control entities and ensures personal safety and investment protection. Its proper definition and setup has been a major precondition for the operation permit by the authorities and was inspected by external reviewers several times. The safety control systems has a distributed architecture comprising of the central safety system with safety signal interfaces attached to components like the cryo plant, superconducting magnets, heating systems and many more. These components have either a local safety control system or just actuators that are directly controlled by the safety signals.The development and commissioning process has been established according to the engineering standard for functional safety in industrial processes (IEC 60511). The development processes with respect to the safety instrumented system starts with the safety requirements specification, in which safety instrumented functions are defined. On the requirements level, the unified modelling language and finite state machine simulations have been used for confirmation of the desired functionality. The software runs on a fault tolerant Siemens PLC with distributed interface Profibus-Safe devices and has been implemented with the Siemens PCS7 programming environment.The commissioning has been done in two steps, one stage for the evacuation and cool-down of the cryostat and the final stage for the preparation of the first plasma. The safety programs have been verified for both development stages and finally validated against the safety instrumentation functions. Throughout the development and commission process the personal safety had to be ensured while deploying new safety program releases and performing integration tests of attached components.
