The development of the ITER control system has accelerated. A successful conceptual design [1] review of the Control Data Access and Communication (CODAC) system was concluded in November, 2007, and confirmed the clearly defined three vertical tiers and two horizontal layers of the system. The vertical tiers distinguish the control, interlock and safety functions. The horizontal layers separate the central control and the plant system control. The central control is under the responsibility of IO, while most of the plant system control is under the responsibility of the seven ITER member parties. This responsibility sharing poses a major challenge for realization and integration of the complete ITER instrumentation and control (I & C) system. In order to mitigate this risk, IO now enlarged the original scope of CODAC group by introducing the responsibility of supporting the plant systems to define their I & C specifications and help follow them through production and different acceptance tests and commissioning. Prerequisite to this activity is standardization in terms of hardware, software and methodology to be accepted by the ITER member parties. Initial progress has been made in this area of standardization. The aim of this paper is to provide a status update of the ITER control system after inclusion of changes during the conceptual design review of 2007 and the increased functional capabilities.
