The ITER CODAC network design

Abstract The ITER CODAC (Control, Data Access and Communication) system is the conventional central control system responsible for operating the ITER facility. CODAC Networks comprise Plant Operation Network (PON), Time Communication Network (TCN), Synchronous Databus Network (SDN) and Data Archiving Network (DAN). CODAC networks connect all plant systems to the central control system through one or more networks depending on the requirements of the plant system I&Cs. The CODAC network infrastructure has been defined including network topology, backbone cable and space allocation network equipment in different ITER plant buildings. This paper presents the design of the current network infrastructure and the four functional networks. This paper also presents the implementation plan of the CODAC network according to the ITER project schedule.
