Leveraging Local Intelligence to Industrial Control Systems through Edge Technologies / Patil, Abhit (CERN) ; Daniel, Schall (Unlisted, AT) ; Ghawash, Faiq (CERN) ; Kaufmann, Thomas (Unlisted, AT) ; Kern, Christian (Unlisted, DE) ; Schofield, Brad (CERN) ; Sündermann, Axel (Unlisted, AT) ; Varela, Fernando (CERN)
Industrial processes often use advanced control algorithms such as Model Predictive Control (MPC) and Machine Learning (ML) to improve performance and efficiency. However, deploying these algorithms can be challenging, particularly when they require significant computational resources and involve complex communication protocols between different control system components. [...]

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. [...]

Consolidation and Redesign of CERN Industrial Controls Frameworks / Golonka, Piotr (CERN) ; Varela, Fernando (CERN)
The Industrial Controls Frameworks, JCOP and UNICOS, have been employed to develop hundreds of critical controls applications in multiple domains like the detector control system, accelerator complex (cryogenics, powering, interlocks) or technical infrastructure, leading to an unprecedented level of homogeneity. These frameworks, used by a thousand of developers worldwide, will now undergo a major consolidation and re-engineering effort to prepare them for the new challenges of the next 20 years in the HL-LHC era, and streamline their maintenance. [...]

Model learning algorithms for anomaly detection in CERN control systems / Tilaro, Filippo (CERN) ; Bradu, Benjamin (CERN) ; Gonzalez-Berges, Manuel (CERN) ; Roshchin, Mikhail (Siemens, Munich) ; Varela, Fernando (CERN)
The CERN automation infrastructure consists of over 600 heterogeneous industrial control systems with around 45 million deployed sensors, actuators and control objects. Therefore, it is evident that the monitoring of such huge system represents a challenging and complex task. [...]

MARS: Easing maintenance and interventions for CERN controls / Varela, Fernando (CERN) ; Epting, Uwe (CERN) ; Gonzalez Corral, Montserrat (CERN) ; Mandilara, Eleni (CERN) ; Podgorski, Stanislaw (CERN)
Industrial control systems for the CERN technical infrastructure and accelerator complex consist of a myriad of devices and components geographically distributed around the CERN facilities. In the event of an intervention in such systems, the on-call engineer or the system expert needs detailed information about the nature of the problem, e.g. [...]

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.

A homogenous approach to CERN/vendor collaboration projects for building OPC-UA servers / Farnham, Ben (CERN) ; Varela, Fernando (CERN) ; Ziogas, Nick (CERN)
Industrial power supplies deliver high and low voltage to a wide range of CERN's detector and accelerator components. These power supplies, sourced from external companies, are integrated into control systems via industry standard OPC servers. [...]

Monitoring of CERN's Data Interchange Protocol (DIP) system / Copy, Brice (CERN) ; Mandilara, Eleni (CERN) ; Prieto Barreiro, Ivan (CERN) ; Varela, Fernando (CERN)
CERN's Data Interchange Protocol (DIP) [1] is a publish-subscribe middleware infrastructure developed at CERN to allow lightweight communications between distinct industrial control systems (such as detector control systems or gas control systems). DIP is a rudimentary data exchange protocol with a very flat and short learning curve and a stable specification. [...]
