Integrating Industrial Control Systems into the Control Environments
of the Technical Infrastructure of CERN

At CERN, the tendency is to have more and more systems of its technical infrastructure controlled locally by industrial systems (PLC) which are supplied by different manufacturers, and which are also increasingly installed and configured by out industrial partners. These diverse systems need to be integrated into the existing control environment, which in fact is part of the accelerator control system, to provide a uniform environment for supervision by the Technical Control Room (TCR).

Recently, several systems for electrical distribution, cooling water, safety and controlled access to accelerator radiation zones were equipped with new controls and had to be integrated.

This paper describes the adopted solutions for common interface standards, selected hardware systems and software packages, and the collaboration with industrial partners; it also discusses the problems encountered.
