The overall control architecture of the European Tritium Handling Experimental Laboratory
The overall control architecture serving the European Tritium Handling Experimental Laboratory (ETHEL) consists of two types of apparatus: (i) programmable logic controllers (PLCs), personal computers (PCs) and networks which constitute the so-called distributed digital control system (DDCS); (ii) fail-safe hard-wiring which operates independently of the DDCS. This paper deals with the first type of apparatus; its hardware and software are described. The computerised system, defined by a four-level hierarchical and modular architecture, is a large distributed real-time control system. The operation is mainly centralised in the control room through a fully programmable man-machine interface (graphic displays, trends, etc.).
