UNICOS AND CPCIndustrial Controls &Safety SystemsBeams Department Process. Methods of changing or refining raw materials to create endproducts. Process control refers to the methods that are used to control processvariables when manufacturing a product. Manufacturers control the production process for several reasons:Reduces variability: increase qualityIncreases efficiency: increase profitsEnsures safety: optimize conditionsSession 0: From specs to implementation2

UNICOS AND CPCIndustrial Controls &Safety SystemsBeams Department UNICOS is a framework to create control applications. UNICOS-CPC (Continuous Process Control) is basic package todevelop integrated PLC based process control applications.Session 0: From specs to implementation3

A LOOK TO THE PASTIndustrial Controls &Safety SystemsBeams Department [1998] UNICOS (UNified Industrial Control System) was born at CERN as a needto develop the LHC cryogenics control system. The goal was to create anindustrial control system covering the three layers of the typical automationpyramid. [2002] UNICOS replace the PcVue SCADA and adopt ETM’s PVSS under theCERN recommendation. [2004] UNICOS offered the choice of creating applications based on SIEMENSS7 PLCs [2009] UNICOS turned into de facto standard framework to develop industrialcontrol applications at CERN:Cryogenics, Cooling, HVAC, Vacuum, Interlocks, [2010] The UNICOS framework has been extended to other kinds of applications(i.e.: supervisory: [QPS,SURVEY], monitoring, ) [2012] Re-engineering processSession 0: From specs to implementation5

FIELD OBJECTS Functionality Industrial Controls &Safety SystemsBeams DepartmentModel the real field equipments (e.g. pumps, valves )As a general rule, the field objects are connected to the I/O Objects. Nodirect connection to the PLC periphery.Types OnOff: Binary Objects(e.g. on/off valve, motor, pump) Analog: Analog objects(e.g. control valve, heater) Anadig: Analog inputs and Digital outputs objects(e.g. valves/heaters controlled by on/off pulses) AnaDO : Similar functionality of an OnOff Analog object(Motor with VFD, Thyristor, Heater, etc.) Local: Field localized objects :(e.g. manual valve)Session 0: From specs to implementationWidget examples13

OPERATION MODES Industrial Controls &Safety SystemsBeams DepartmentAuto ModeThe object is driven by the control logic of a higher object of the hierarchy. Interlocks apply to the request Manual Mode (requested by operators via the OWS) Forced Mode (requested by operators via the OWS) The automatic return to the auto mode is possible by the control logic.Interlocks apply to the requestThe automatic return to the auto mode is impossible by the control logic.Interlocks apply to the requests.Local mode Hardware Local Mode The object is driven locally by the process field (activated via a DI)E.g. maintenance purposesSoftware Local Mode (requested by operators via the Local panels) The Local software is writing directly in the manual requests of the objectsPriority over "Auto" and "Manual" mode. The "forced mode" setup by thenormal SCADA can override the software local mode.Interlocks apply to the requests.Session 0: From specs to implementation17
