CODAC systems arrangement and connectivity
2013
Abstract The CODAC system is responsible for integrating all ITER plant system Instrumentation and Control systems and enabling operation of ITER machine as a single integrated facility. The different ITER plant systems and their Instrumentation and Control systems are distributed in several ITER buildings on the ITER platform. The CODAC systems have to interface with all these distributed plant system I&C systems. CODAC systems will be composed of several physical systems or components like networks, servers, workstations (terminals), large displays, PSH, storage systems etc. Several rooms in different buildings have been defined to house all above equipment. The site-wide CODAC network infrastructure will be based on a dual (redundant) star topology. The two redundant star points will house the core networking switches. These redundant core switches will be installed in different buildings. Cubicles used for network infrastructure are distributed among “hutches,” where a CODAC hutch is a room or area equipped with appropriate heating, ventilation, air conditioning and uninterruptible power which will be directly connected through two star points. The responsibility of CODAC infrastructure ends up to the plant system I&C cubicles so several passive CODAC network panels have identified in all I&C rooms of different plant buildings. This CODAC Network Panel will be the physical termination point for CODAC Network infrastructure. The CODAC Network cables running from the nearest CODAC Network hutch will terminate in these panels. Network panels are installed at strategic locations close to plant system I&C cubicles. This paper will describe more details about the physical arrangement of CODAC systems in different buildings on ITER platform for different purpose and their planned connectivity. This paper will also provide more information about the volume allocations for CODAC components, planned cabling arrangement and other infrastructure requirements like electrical and cooling etc.
