Generic control system design for the Cassette Multifunctional Mover and other ITER remote handling equipment

A new suite of Remote Handling (RH) equipment, addressing the latest design of the divertor region, is currently being specified for ITER, with procurement of the Cassette Multifunctional Mover (CMM) scheduled for 2005-2006. This presents a unique opportunity to address a vital component of the RH system - the control system - and this paper introduces a number of concepts based on replication of design and implementation for functionally similar RH systems. Correctly implemented, this should improve equipment availability and reliability, reduce overall support requirements, and minimise the risks of serious failure.
