Continuous Integration for PLC-based Control Systems / Schofield, Brad (CERN) ; Blanco Viñuela, Enrique (CERN) ; Borrego, João (CERN ; Lisbon U.)
Continuous integration is widespread in software development, but a number of factors have thus far limited its use in PLC (Programmable Logic Controller) application development. A key requirement of continuous integration is that build and test stages must be automated. [...]

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. [...]

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. [...]

PLCverif: A Tool to Verify PLC Programs Based on Model Checking Techniques / Darvas, Dániel (CERN) ; Blanco Vinuela, Enrique (CERN) ; Fernández Adiego, Borja (CERN)
Model checking is a promising formal verification method to complement testing in order to improve the quality of PLC programs. However, its application typically needs deep expertise in formal methods. [...]

Waste Heat Recovery for the LHC Coooling Towers: Control System Validation Using Digital Twins / Schofield, Brad (CERN) ; Blanco Viñuela, Enrique (CERN) ; Booth, William (CERN) ; Peljo, Matias (Aalto U.)
In order to improve its energy utilization, CERN will deploy a Waste Heat Recovery system at one of the LHC’s surface sites which will provide heating power to a local municipality. To study the effects that the heat recovery plant will have on the cooling system, a ’digital twin’ of the cooling plant was created in the simulation tool EcosimPro. [...]

PROFINET communication card for the CERN cryogenics crate electronics instrumentation / Mastyna, Rafal (CERN) ; Blanco Viñuela, Enrique (CERN) ; Casas, Juan (CERN) ; Felser, Max (BFH, Bern) ; Trikoupis, Nikolaos (CERN)
The ITER-CERN collaboration agreement initiated the development of a PROFINET communication interface which may replace the WorldFIP interface in non-radiation areas. The main advantage of PROFINET is a simplified integration within the CERN controls infrastructure that is based on Programmable Logic Controllers (PLCs). [...]

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. [...]

Data analytics reporting tool for CERN SCADA systems / Seweryn, Piotr (CERN) ; Gonzalez-Berges, Manuel (CERN) ; Schofield, Brad (CERN) ; Tilaro, Filippo (CERN)
This paper describes the concept of a generic data analytics reporting tool for SCADA (Supervisory Control and Data Acquisition) systems at CERN. The tool is a response to a growing demand for smart solutions in the supervision and analysis of control systems data. [...]

Applying model checking to critical PLC applications : An ITER case study / Fernández Adiego, Borja (CERN) ; Avinashkrishna, Bhimavarapu (TCS, Madhapur) ; Blanco Viñuela, Enrique (CERN) ; Darvas, Daniel (CERN) ; Gaikwad, Yogesh (TCS, Madhapur) ; Lee, Gisik (Mobiis Co. Ltd., Seoul) ; Pedica, Riccardo (Vitrociset, Rome) ; Prieto Diaz, Ignacio (IBERINCO, Madrid) ; Sallai, Gyula (Budapest, Tech. U.) ; Sreekuttan, Sailaraj (TCS, Madhapur)
The development of critical systems requires the application of verification techniques in order to guarantee that the requirements are met in the system. Standards like IEC 61508 provide guidelines and recommend the use of formal methods for that purpose. [...]
