Requirements Management Support For The Iter Plasma Control System In View Of First Plasma Operations

In a complex project as the ITER one, it is essential to rely on a system-engineering oriented approach for requirements management, to both track the development of the various systems and to assess their compliance with the requirements set expressed at each operational phase. Such an approach is currently adopted for the ITER Plasma Control System (PCS), where a database implemented using the Enterprise Architect tool has been setup to act as the central collaboration tool for all the PCS system design.This paper describes the current structure of the PCS DB, and presents examples on the interfacing of the PCS and diagnostics, relevant for first plasma operations.
