	ITER is formed by systems which shall be pushed to their performance limits in order to successfully achieve the scientific goals. The scientists in charge of exploiting the tokamak will require enough operational flexibility to explore as many plasma scenarios as possible while being sure that the integrity of the machine and safety of the environment and personnel are not compromised. The I&C Systems of ITER has been divided in three separate tiers: the conventional I&C, the safety system and the interlock system. This paper focuses on the latter. The design of the ITER interlocks has to take into account the intrinsic diversity of ITER systems, which implies a diversity of risks to be mitigated and hence the impossibility to implement a unique solution for the whole machine. This paper presents the chosen interlock solutions based on PLC, FPGA, and hardwired technologies. It also describes how experience from existing tokamaks has been applied to the design of the ITER interlocks, as well as the ITER particularities that have forced the designers to evaluate some technical choices which historically have been considered as non-suitable for implementing interlock functions.
