Large-scale upgrade campaigns of SCADA systems at CERN - organisation, tools and lessons learned / Kulaga, Rafal (CERN) ; Arroyo Garcia, Jonas (CERN) ; Boccioli, Marco (PSI, Villigen) ; Genuardi, Enzo (CERN) ; Golonka, Piotr (CERN) ; Gonzalez Berges, Manuel (CERN) ; Tournier, Jean-Charles (CERN) ; Varela, Fernando (CERN)
The paper describes planning and execution of large-scale maintenance campaigns of SCADA systems for CERN's accelerator and technical infrastructure. These activities, required to keep up with the pace of development of the controlled systems and rapid evolution of software, are constrained by many factors, such as availability for operation and planned interventions on equipment.

Future archiver for CERN SCADA systems / Golonka, Piotr (CERN) ; Gonzalez-Berges, Manuel (CERN) ; Guzik, Jakub (CERN) ; Kulaga, Rafal (CERN)
The paper presents the concept of a modular and scalable archiver (historian) for SCADA systems at CERN. By separating concerns of archiving from specifics of data-storage systems at a high abstraction level, using a clean and open interface, it will be possible to integrate various data handling technologies without a big effort. [...]

CERN SCADA Systems 2020 Large Upgrade Campaign Retrospective / Goralczyk, Lukasz (CERN) ; Kostopoulos, Alexandros Foivos (CERN) ; Schofield, Brad (CERN) ; Tournier, Jean-Charles (CERN)
In this paper we report the experience from a large-scale upgrade campaign of SCADA control systems performed during the second LHC Long Shutdown at CERN. Such periodical upgrades are dictated by the ever evolving SCADA WinCC OA system and the CERN frameworks evolution used in those control systems. [...]

MONARC: Supervising the Archiving Infrastructure of CERN Control Systems / Tournier, Jean-Charles (CERN) ; Blanco Viñuela, Enrique (CERN)
The CERN industrial control systems, using WinCC OA as SCADA (Supervisory Control and Data Acquisition), share a common history data archiving system relying on an Oracle infrastructure. It consists of 2 clusters of two nodes for a total of more than 250 schemas. [...]

SCADA statistics monitoring using the Elastic Stack (Elasticsearch, Logstash, Kibana) / Hamilton, James (CERN) ; Gonzalez Berges, Manuel (CERN) ; Schofield, Brad (CERN) ; Tournier, Jean-Charles (CERN)
The Industrial Controls and Safety systems group at CERN, in collaboration with other groups, has developed and currently maintains around 200 controls applications that include domains such as LHC magnet protection, cryogenics and electrical network supervision systems. Millions of value changes and alarms from many devices are archived to a centralised Oracle database but it is not easy to obtain high-level statistics from such an archive. [...]

Enhanced Maintenance and Availability of Handling Equipment using IIoT Technologies / Blanco Viñuela, Enrique (CERN) ; Garcia Fernandez, Adrian (CERN) ; Lafarge, Damien (CERN) ; Thomas, Geraldine (CERN) ; Tournier, Jean-Charles (CERN)
CERN currently houses 6000 handling equipment units categorized into 40 different families, such as electric overhead travelling cranes (EOT), hoists, trucks, and forklifts. These assets are spread throughout the CERN campus, on the surface (indoor and outdoor), as well as in underground tunnels and experimental caverns. [...]

Applying Model Checking to Highly-Configurable Safety Critical Software: The SPS-PPS PLC Program / Fernández Adiego, Borja (CERN) ; Blanco Viñuela, Enrique (CERN) ; Havart, Frederic (CERN) ; Ladzinski, Tomasz (CERN) ; Lopez-Miguel, Ignacio D (CERN) ; Tournier, Jean-Charles (CERN)
An important aspect of many particle accelerators is the constant evolution and frequent configuration changes that are needed to perform the experiments they are designed for. This often leads to the design of configurable software that can absorb these changes and perform the required control and protection actions. [...]

Scaling Up the Deployment and Operation of an ELK Technology Stack / Boychenko, Serhiy (CERN) ; Martel, Pedro (CERN) ; Schofield, Brad (CERN)
Since its integration into the CERN industrial controls environment, the SCADA Statistics project has become a valuable asset for controls engineers and hardware experts in their daily monitoring and maintenance tasks. The adoption of the tool outside of the Industrial Controls and Safety Systems group scope is currently being evaluated by ALICE, since they have similar requirements for alarms and value changes monitoring in their experiment.

Integration of the vacuum SCADA with CERN's Enterprise Asset Management system / Rocha, Andre (CERN) ; Blanchard, Sebastien (CERN) ; Fraga, Jorge (CERN) ; Gkioka, Georgia (CERN) ; Gomes, Paulo (CERN) ; Gonzalez, Luis (CERN) ; Krastev, Tsvetelin (CERN) ; Riddone, Germana (CERN) ; Widegren, David (CERN)
With over 128Km of vacuum chambers, reaching pressures as low as in interstellar space, CERN is home to the largest vacuum system in the world. Its underlying architecture comprises approximately 15 000 pieces of control equipment, supervised and controlled by 7 Supervisory Control And Data Acquisition (SCADA) servers, and over 300 Programmable Logic Controllers (PLCs).

Developing and Validating OPC-UA Based Industrial Controls for Power Supplies at CERN / Ludwig, Michael (CERN) ; Arroyo Garcia, Jonas (CERN) ; Bengulescu, Marc (CERN) ; Farnham, Ben (CERN) ; Gonzalez Jimenez, Pablo (CERN) ; Varela, Fernando (CERN)
The industrial control systems of CERN’s experiments are undergoing major renovation since 2017 and well into CERN’s second Long Shutdown (LS2) until the end of 2019. Each detector power-supply control system runs several hundred software instances consisting of many different components in parallel on a large scale, broadly distinguishable as servers and clients.
