Control systems for ITER diagnostics, heating and current drive

The paper will describe the formal processes of control system design and the methods used by the ITER project to achieve the standardization of systems engineering practices. These have been applied to several use-cases covering all operation relevant phases such as plasma operation, maintenance, testing and conditioning. There are a number of running contracts that are developing the control designs, including on which is preparing detailed diagnostic use-cases to help designers out in the field. The ITER International Organization will reinforce the methodology by holding regular User Meetings, in which successes and problems can be shared. Also, the distribution of CODAC Cores Systems and the holding of Hands-On Workshops is intended to help users in the Domestic Agencies and their suppliers to buy in to the standardization and to build compatible I&C systems, which will integrate seamlessly into CODAC when they arrive on the ITER site.
