The EN-CV-CL section is reponsible for all control systems produced for the EN-CV installations.The EN-CV control system architecture is composed by several layers:
- - Actuators and sensors for equipment control and feedback
- - Fieldbuses for equipment connections to PLCs
- - PLCs of several brands: Siemens, Schneider and WAGO
- - SCADA servers as well as alarm and archive servers
- - Operator Work Stations
Since 2012 the section has produced several hundred control systems with the UNICOS framework, which are supervised with the WinCC OA SCADA system. Almost all new systems are programmed with the UNICOS framework. On the long term, UNICOS will replace all existing control systems.
Historically, control systems have been developed with different SCADA systems. A small number of control systems are programmed with standard PLC development tools and supervised with the PCVue SCADA system. The following PCVue SCADA systems are in operation:
- Detector Cooling for the ATLAS, CMS and ALICE experiments
- COOLUSC55 Subdetector
- LHC Ventilation
In addition, the section operates a number of simple control systems supervised with WinCC Flexible:
- LHC Water Treatment
- 378 Demineralized Water
- Cooling Isolde
- Compressed air building 200
- Cooling POPS
- Ventilation NTOF
- Ventilation POPS
- Ventilation PSB Dump
- 513 Vault HVAC
- Point 8 SX8
A few control systems do not have dedicated SCADA systems, but some remote monitoring facilities are available via the CERN Alarm System (LASER) and the Technical Infrastructure Monitoring (TIM) tools.
It is possible to connect remotely to the SCADA systems. For details, refer to the documentation related to Remote Connections
