Working Together for Safer Systems: A Collaboration Model for Verification of PLC Code / Lopez-Miguel, Ignacio D (TU Vienna) ; Betz, Christine (Darmstadt, GSI) ; Blanco Viñuela, Enrique (CERN) ; Fernández Adiego, Borja (CERN) ; Salinas, Matias (Darmstadt, GSI)
Formal verification techniques are widely used in critical industries to minimize software flaws. However, despite the benefits and recommendations of the functional safety standards, such as IEC 61508 and IEC 61511, formal verification is not yet a common practice in the process industry and large scientific installations.

Life Cycle Management and Reliability Analysis of Controls Hardware Using Operational Data From EAM / Fortescue, Eve (CERN) ; Kozsar, Ioan (CERN) ; Schramm, Volker (Stuttgart U.)
The use of operational data from Enterprise Asset Management(EAM) systems has become an increasingly popular approach for conducting reliability analysis of industrial equipment. This paper presents a case study of how EAM data was used to analyse the reliability of CERN’s standard controls hardware, deployed and maintained by the Controls Electronics and Mechatronics group.

Energy Consumption Optimisation by Using Advanced Control Algorithms / Ghawash, Faiq (CERN ; Norwegian U. Sci. Tech.) ; Blanco Viñuela, Enrique (CERN) ; Schofield, Brad (CERN)
Large industries operate energy-intensive equipment and energy efficiency is an important objective when trying to optimize the final energy consumption. CERN utilizes a large amount of electrical energy to run its accelerators, detectors and test facilities, with a total yearly consumption of 1.3 TWh and peaks of about 200 MW. [...]

Protecting Your Controls Infrastructure Supply Chain / Copy, Brice (CERN) ; Ehm, Felix (CERN) ; Elson, Philip (CERN) ; Page, Stephen (CERN) ; Pratoussy, Martin (CERN) ; Van Mol, Lucas (CERN) ; de Martel, Jean-Baptiste (CERN)
Supply chain attacks have been constantly increasing since being first documented in 2013. Profitable and relatively simple to put in place for a potential attacker, they compromise organizations at the core of their operation. [...]

A Modular Approach for Accelerator Controls Components Deployment for High Power Pulsed Systems / Pavis, Steven (CERN) ; Barlow, Roger (CERN) ; Boucly, Christophe (CERN) ; Carlier, Etienne (CERN) ; Chanavat, Christophe (CERN) ; Lolliot, Christophe (CERN) ; Magnin, Nicolas (CERN) ; Van Trappen, Pieter (CERN) ; Voumard, Nicolas (CERN)
As part of the LHC Injector Upgrade (LIU) project, the controls of the PSB and PS injection kickers at CERN have been upgraded during Long Shutdown 2 (LS2) from heterogeneous home-made electronic solutions to a modular and open architecture. Despite both kickers have significantly different functionalities, topologies and operational requirements, standardized hardware and software control blocks have been used for both systems. [...]

Towards Automatic Generation of Fail-Safe PLC Code Compliant with Functional Safety Standards / Germinario, Andrea (CERN) ; Blanco Viñuela, Enrique (CERN) ; Fernández Adiego, Borja (CERN)
In agreement with the IEC 61511 functional safety standard, fail-safe application programs should be written using a Limited Variability Language (LVL), that has a limited number of operations and data types, such as LD (Ladder Diagrams) or FBD (Function Block Diagrams) for safety PLC (Programmable Logic Controller) languages. The specification of safety instrumented systems, as part of the Safety Requirements Specification document, shall unambiguously define the logic of the program, creating a one-to-one relationship between code and specification.

The Micro-Services of Cern’s Critical Current Test Benches / Charrondière, Cedric (CERN) ; Andreassen, Odd (CERN) ; Ballarino, Amalia (CERN) ; Barth, Christian (CERN) ; Boutboul, Thierry (CERN) ; Fleiter, Jerome (CERN) ; Hopkins, Simon (CERN) ; Koziol, Piotr (CERN) ; Reymond, Hubert (CERN)
In order to characterize the critical-current density of low temperature superconductors such as niobium¿titanium (NbTi) and niobium¿tin (Nb₃Sn) or high temperature superconductors such as magnesium-diboride MgB₂ or Rare-earth Barium Copper Oxide REBCO tapes, a wide range of custom instruments and interfaces are used. The critical current of a superconductor depends on temperature, magnetic field, current and strain, requiring high precision measurements in the nano Volt range, well-synchronized instrumentation, and the possibility to quickly adapt and replace instrumentation if needed.
