UNICOS

UNICOS is a CERN framework developed to produce control applications for three-layer control systems. UNICOS provides developers with the means to rapidly develop full control or monitoring applications and provides operators with ways to interact with all the items of the process from the most simple (e.g. I/O channels) to the high level compound devices with little effort. In addition UNICOS offers tools to diagnose problems in the process, the control system and to access and operate the devices without specific development.

The framework proposes a reusable environment composed of a set of components for the unicos-pvss and unicos-front-end parts:

• UNICORE where packages can be added.
• A basic package called UNICOS Continous Process Control (CPC) is offered to develop process control applications. CERN examples of the usage of UNICOS CPC are the LHC Cryogenics control, the LHC Gas Control System (GCS) and the collimator interlocks applications.

In addition to the sofware components UNICOS provides a methodology to create the control implementation of complex system together with Autaomated code production tools for Front ends and supervision.

The full UNICOS implementation was primary designed for the LHC accelarator cryogenics and for the Experience cryogenics control system (ATLAS,CMS)

Note: the UNICOS methodology is compliant with ISA S88
