UNICOS (UNified Industrial Control System) is a CERN-made framework to develop industrial control applications. It deals with the two upper layers of a classical control system: Supervision and Control. UNICOS proposes a method to design and develop the control application which will run in commercial off-the-shelf products (e.g. SCADA and PLCs). The framework employs terminology and models of the ISA-88 standard for batch control systems.\ The goal of UNICOS is to standardize the development of control applications at CERN by:

• Emphasize good practices for both, design and operation, of the continuous process control applications
• Reduce the cost of automating continuous processes (e.g. cooling, HVAC...)
• Optimize life-cycle engineering efforts (e.g. using automatic code generation tools)
