Protection Layers Design for the High Luminosity LHC Full Remote Alignment System / Fernández Adiego, Borja (CERN) ; Blanco Viñuela, Enrique (CERN) ; Germinario, Andrea (CERN) ; Mainaud Durand, Helene (CERN) ; Sosin, Mateusz (CERN)
The Full Remote Alignment System (FRAS) is a complex measurement, alignment and control system designed to remotely align components of the Large Hadron Collider (LHC) following its High Luminosity upgrade. The purpose of FRAS is to guarantee optimal alignment of the strong focusing magnets and associated components near the experimental interaction points, while at the same time limiting the radiation dose to which surveyors in the LHC tunnel are subjected.

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. [...]

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. [...]

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. [...]

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.

Continuous Integration for PLC-based Control System Development / Schofield, Brad (CERN) ; Blanco Viñuela, Enrique (CERN) ; Borrego, João (CERN)
Continuous Integration and Continuous Deployment (CI/CD) is a software engineering methodology which emphasises frequent, small changes committed to a version control system, which are verified by a suite of automatic tests, and which may be deployed to different environments. While CI/CD is well established in software engineering, it is not yet widely used in the development of industrial controls systems. [...]

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. [...]

The design and development of Safety Instrumented Systems (SIS) according to the IEC 61511 standard is a long and costly process. Although the standard gives recommendations and guidelines for each phase of the safety life-cycle, implementing them is not a simple task. [...]
