Scada
What is SCADA?
Axel Daneels, Wayne Salter , IT/CO
Abstract
An industrial SCADA system will be used for the development of the controls of the four LHC experiments. This paper describes the SCADA systems in terms of their architecture, their interface to the process hardware, the functionality and the application development facilities they provide. Some attention is also paid to the industrial standards to which they abide, their planned evolution as well as the potential benefits of their use.
1. Introduction
On 20 Sept. 2000, the Finance Committee approved the proposal to negotiate a contract with ETM A.G. (Eisenstadt, Austria) for the supply of PVSS - ETM 's SCADA - for developing the control systems of ALICE, ATLAS, CMS and LHCb. In addition the SCADA Working Group, that was set up by the CERN Controls Board, recommends PVSS as one of the SCADA products for the development of future control systems at CERN.
These decisions are the accomplishment of around thirteen person-years (FTE) of effort - spanning over more than three years - to identify and evaluate a proper industrial control system that copes with the extreme requirements of high energy particle physics experiments such as those of the LHC.
Widely used in industry for Supervisory Control and Data Acquisition of industrial processes, SCADA systems are now also penetrating the experimental physics laboratories for the controls of ancillary systems such as cooling, ventilation, power distribution, etc. More recently they were also applied for the controls of smaller size particle detectors such as the L3 muon detector and the NA48 experiment, to name just two examples at CERN.
SCADA systems have made substantial progress over the recent years in terms of functionality, scalability, performance and openness such that they are an alternative to in house development even for very demanding and complex control systems as those of physics experiments.
