ITER has developed a specific methodology for the Plant System I&C design. The methodology specifies several design cycles and deliverables covering from preliminary design to manufacturing and site acceptance. The methodology is supported by a set of software tools including Enterprise Architect and Enterprise Architect Add-ins developed by ITER. This methodology has been applied for the design of ITER Upper Visible/Infrared Wide-Angle Viewing System (UWAVS). The ITER UWAVS is a critical diagnostic system for divertor surface temperature monitoring and heat load calculation during plasma operation. This system will be installed after the first plasma phase in five upper ports with front-end optics under vacuum, relay optics in the interspace, back-end optics and sensors in the port-cells, and data acquisition and processing units in the Diagnostic Building. The UWAVS system is currently in the Preliminary Design Phase. The contribution describes how the ITER CODAC methodology for Plant System I&C design has been applied, showing the advantages and main drawbacks found, as well as the current design status of the system. The R&D activities carried out will be presented, including the prototype developed and the preliminary architecture of the system, based on the MTCA form factor and 10GigE cameras. Finally, some R&D challenges will be identified, such as camera high throughput data acquisition and real-time image processing that has been solved.
