TU2AO01	The Hybrid Identity of a Control System Organization: Balancing Support, Product, and R&D Expectations	303
	S. Baymani PSI, Villigen PSI, Switzerland
	Controls organizations are often expected to fulfill a dual role as both a support organization and an R&D organization, providing advanced and innovative services. This creates a tension between the need to provide services and the desire and necessity to develop cutting-edge technology. In addition, Controls organizations must balance the competing demands of product development, maintenance and operations, and innovation and R&D. These conflicting expectations can lead to neglect of long-term strategic issues and create imbalances within the organization, such as technical debt and lack of innovation. This paper will explore the challenges of navigating these conflicting expectations and the common traps, risks, and consequences of imbalances. Drawing on our experience at PSI, we will discuss specific examples of conflicts and their consequences. We will also propose solutions to overcome or improve these conflicts and identify a long-term, sustainable approach for a hybrid organization such as Controls . Our proposals will cover strategies for balancing support and product development, improving communication, and enabling a culture of innovation. Our goal is to spark a broader discussion around the identity and role of control system organizations within large laboratory organizations, and to provide concrete proposals for organizations looking to balance competing demands and build a sustainable approach to control systems and services.

TU2AO03	A Successful Emergency Response Plan: Lessons in the Controls Section of the ALBA Synchrotron	316
	G. Cuní, O. Matilla, J. Nicolàs, M. Pont ALBA-CELLS, Cerdanyola del Vallès, Spain
	These are challenging times for research institutes in the field of software engineering. Our designs are becoming increasingly complex, and a software engineer needs years of experience to become productive. On the other hand, the software job market is very dynamic, and a computer engineer receives tens of offers from private companies with attractive salaries every year. Occasionally, the perfect storm can occur, and in a short period of time, several key people in a group with years of experience leave. The situation is even more critical when the institute is plunged into a high growth rate with several new instruments under way. Naturally, engaged teams will resist reducing operational service quality, but, on the other hand, the new installations milestones dates will approach quickly. This article outlines the decision-making process and the measures taken to cope with this situation in the ALBA Synchroton’s Controls Section. The plan included reorganizing teamwork, but more importantly, redefining the relationship with our clients and prioritization processes. As a result, the team was restructured and new roles were created. In addition, effective coordination was vital, and new communication channels were established to ensure smooth workflows. The emergency peak period is over in our case, but we have learned a lot of lessons and implemented many changes that will stay with us. They have made us more efficient and more resilient in case of future emergencies.

TU2AO04	Ensuring Smooth Controls Upgrades During Operation	321
	M. Pace, F. Hoguin, E. Matli, W. Sliwinski, B. Urbaniec CERN, Meyrin, Switzerland
	The CERN Accelerator Controls systems have to remain as stable as possible for operations. However, there are inevitable needs to introduce changes to provide new functionalities and conduct important consolidation activities. To deal with this, a formal procedure and approval process, the Smooth Upgrades procedure, was introduced and refined over a number of years. This involves declaring foreseen Controls changes as a function of the accelerator schedules, validating them with stakeholders, and organising their deployment in the production environment. All of this with the aim of minimising the impact on accelerator operation. The scope of this activity is CERN-wide, covering changes developed by all CERN units involved in Controls and encompassing the whole CERN accelerator and facility complex. In 2022, the mandate was further extended with a more formal approach to coordinate changes of the software interfaces of the devices running on front-end computers, which form a critical part of the smooth deployment process. Today, Smooth Upgrades are considered a key contributor to the performance and stability of the CERN Control system. This paper describes the Smooth Upgrades procedure and the underlying processes and tools such as schedule management, change management, and the monitoring of device usage. The paper also includes the major evolutions which allowed the current level of maturity and efficiency to be reached. Ideas for future improvements will also be covered.

TU2AO05	Maintenance of the National Ignition Facility Controls Hardware System	328
	J.L. Vaher, G.K. Brunton, J. Dixon LLNL, Livermore, USA
	Funding: This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. At the National Ignition Facility (NIF), achieving fusion ignition for the first time ever in a laboratory required one of the most complex hardware control systems in the world. With approximately 1,200 control racks, 66,000 control points, and 100, 000 cables, maintaining the NIF control system requires an exquisite choreography around experimental operations while adhering to NIF’s safety, security, quality, and efficiency requirements. To ensure systems operate at peak performance and remain available at all times to avoid costly delays, preventative maintenance activities are performed two days per week as the foundation of our effective maintenance strategy. Reactive maintenance addresses critical path issues that impact experimental operations through a rapid response 24x7 on-call support team. Prioritized work requests are reviewed and approved daily by the facility operations scheduling team. NIF is now in the second decade of operations, and the aging of many control systems is threatening to affect performance and availability, potentially impacting planned progress of the fusion ignition program. The team is embarking on a large-scale refurbishment of systems to mitigate this threat. Our robust maintenance program will ensure NIF can capitalize on ignition and push the facility to even greater achievements. This paper will describe the processes, procedures, and metrics used to plan, coordinate, and perform controls hardware maintenance at NIF. LLNL Release Number: LLNL-ABS-848420

	Accelerators and other big science facilities rely heavily on internally developed technologies, including control system software. Much of it can and is shared between labs, like the Tango Controls and EPICS. Then, some of it finds broad application outside science, like the famous World Wide Web. However, there are still a lot of duplicating efforts in the labs, and a lot of software has the potential to be applied in other areas. Increasing collaboration and involving private companies can help avoid redundant work. It can decrease the overall costs of laboratory development and operation. Having private industry involved in technology development also increases the chances of new applications. This can positively impact society, which means effective spending of public funds. The talk will be based on the results of a survey looking at how much scientific institutes and companies focus on collaboration and dissemination in the field of software technologies. It will also include remarks based on the authors’ experiences in building an innovative ecosystem.

TUMBCMO39	Enhanced Maintenance and Availability of Handling Equipment using IIoT Technologies	462
	E. Blanco Viñuela, A.G. Garcia Fernandez, D. Lafarge, G. Thomas, J-C. Tournier CERN, Meyrin, Switzerland
	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. Partial access to some areas, a large area to cover, thousands of units, radiation, and diverse needs among handling equipment makes maintenance a cumbersome task. Without automatic monitoring solutions, the handling engineering team must conduct periodic on-site inspections to identify equipment in need of regulatory maintenance, leading to unnecessary inspections in hard-to-reach environments for underused equipment but also reliability risks for overused equipment between two technical visits. To overcome these challenges, a remote monitoring solution was introduced to extend the equipment lifetime and perform optimal maintenance. This paper describes the implementation of a remote monitoring solution integrating IIoT (Industrial Internet of Things) technologies with the existing CERN control infrastructure and frameworks for control systems (UNICOS and WinCC OA). At the present time, over 600 handling equipment units are being monitored successfully and this number will grow thanks to the scalability this solution offers.

TUPDP001	Working Together for Safer Systems: A Collaboration Model for Verification of PLC Code	467
	I.D. Lopez-Miguel IAP TUW, Wien, Austria C. Betz, M. Salinas GSI, Darmstadt, Germany E. Blanco Viñuela, B. Fernández Adiego CERN, Meyrin, Switzerland
	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. This is mainly due to its complexity and the need for formal methods experts. At CERN, the PLCverif tool was developed to verify PLC programs formally. Although PLCverif hides most of the complexity of using formal methods and removes barriers to formally verifying PLC programs, engineers trying to verify their developments still encounter different obstacles. These challenges include the formalization of program specifications or the creation of formal models. This paper discusses how to overcome these obstacles by proposing a collaboration model that effectively allows the verification of critical PLC programs and promotes knowledge transfer between organizations. By providing a simpler and more accessible way to carry out formal verification, tools like PLCverif can play a crucial role in achieving this goal. The collaboration model splits the specification, development, and verification tasks between organizations. This approach is illustrated through a case study between GSI and CERN.

TUPDP022	DALI Control System Considerations	547
	K. Zenker, M. Justus, R. Steinbrück HZDR, Dresden, Germany
	The Dresden Advanced Light Infrastructure (DALI) is part of the German national Helmholtz Photon Science Roadmap. It will be a high-field source of intense terahertz radiation based on accelerated electrons and the successor of the Center for High-Power Radiation Sources (ELBE) operated at HZDR since 2002. In the current phase of DALI the conceptional design report is in preparation and there are ongoing considerations which control system to use best. We will present the status of those considerations, that include defining the requirements for the control system and a discussion of control system candidates. In the early conceptional phase we are still open to any control system that can fulfill our requirements. Besides pure technical performance, features and security the requirements encompass modernity, well established support by community and companies, long term availability as well as collaboration potential and benefit. To collect opinions from the community on what is the optimal control system we prepared a survey. Like that we would like to benefit as much as possible from the community experience with different types of control systems.

TUPDP049	15 Years of the J-PARC Main Ring Control System Operation and Its Future Plan	639
	S. Yamada J-PARC, KEK & JAEA, Ibaraki-ken, Japan
	The accelerator control system of the J-PARC MR started operation in 2008. Most of the components of the control computers, such as servers, disks, operation terminals, front-end computers and software, which were introduced during the construction phase, have gone through one or two generational changes in the last 15 years. Alongside, the policies for the operation of control computers have changed. This paper reviews the renewal of those components and discusses the philosophy behind the configuration and operational policy. It is also discusses the approach to matters that did not exist at the beginning of the project, such as virtualization or cyber security.

TUPDP067	Unified Systems Engineering Methodology for the Design of ITER Diagnostic Systems
	R. Modic, L. Cerne, H. Raiji, D. Sarajlic Cosylab, Ljubljana, Slovenia S. Simrock ITER Organization, St. Paul lez Durance, France
	To control and monitor the plasma, ITER will use a number of different diagnostic systems, each with its own operating principle, and composed of different components. The systems will go through several design stages, and a unified systems engineering methodology is needed that will generate comparable design outputs for validation, integration and assembly of the systems. However, having the same methodology for such different systems means that it has to be general enough, such that the requirements of different systems are covered, the challenge being to find a compromise between the high-level approach and the final usability of the system design. The methodology needs to be such that sufficient input is provided to the developers and engineers in the successive phases, in an effort to minimize the risks in the development and integration phases. With the goal of addressing these challenges, a common systems engineering methodology for the design of ITER diagnostic systems was derived; Cosylab tested and validated this methodology by applying it to several diagnostic systems, and also identified and implemented improvements and developments to this methodology; lessons learned and observations made in the process of applying this methodology will allow systems engineers to gain a deeper insight into the relationship between systems engineering, architecture and design, and project management, in the domain of fusion-specific developments.

TUPDP074	Managing Robotics and Digitization Risk	676
	D. Marais, J.C. Mostert, R. Prinsloo NECSA, Hartbeespoort, South Africa
	Robotic and digitization risks refer to the potential negative consequences that can arise from the use of robots and digital technologies in various industries, which include experimental physics control systems. Risks include the compromising or malfunctioning of these systems, resulting in injury, equipment damage, loss of data or disruptions to critical infrastructure and services. Mitigating these risks involves taking proactive steps to reduce the likelihood of negative consequences and minimize their impact if they do occur. A comprehensive risk management approach that incorporates a combination of technical, organizational, and cultural strategies can help mitigate the potential risks through the implementation of the following strategies which will be discussed in this presentation: Regular maintenance and testing of robotic systems; Implementation of strong cyber security measures; Employee training and awareness programs; Adoption of industry standards and best practices; Developing contingency plans and backup systems; Establishing clear ethical and social guidelines.

TUPDP092	Life Cycle Management and Reliability Analysis of Controls Hardware Using Operational Data From EAM	758
	E. Fortescue, I. Kozsar, V. Schramm CERN, Meyrin, Switzerland
	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. The first part of the study involved the extraction, treatment and analysis of state-transition data to detect failures. The analysis was conducted using statistical methods, including failure-rate analysis and time-to-failure analysis to identify trends in equipment performance and plan for future obsolescence, upgrades and replacement strategies. The results of the analysis are available via a dynamic online dashboard. The second part of the study considers Front-End computers as repairable systems, composed of the previously studied non-repairable modules. The faults were recorded and analysed using the Accelerator Fault Tracking system. The study brought to light the need for high quality data, which led to improvements in the data recording process and refinement of the infrastructure team’s workflow. In the future, reliability analysis will become even more critical for ensuring the cost-effective and efficient operation of controls systems for accelerators. This study demonstrates the potential of EAM operational data to provide valuable insights into equipment reliability and inform decision-making for repairable and non-repairable systems.

Funding: This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
At the National Ignition Facility (NIF), achieving fusion ignition for the first time ever in a laboratory required one of the most complex hardware control systems in the world. With approximately 1,200 control racks, 66,000 control points, and 100, 000 cables, maintaining the NIF control system requires an exquisite choreography around experimental operations while adhering to NIF’s safety, security, quality, and efficiency requirements. To ensure systems operate at peak performance and remain available at all times to avoid costly delays, preventative maintenance activities are performed two days per week as the foundation of our effective maintenance strategy. Reactive maintenance addresses critical path issues that impact experimental operations through a rapid response 24x7 on-call support team. Prioritized work requests are reviewed and approved daily by the facility operations scheduling team. NIF is now in the second decade of operations, and the aging of many control systems is threatening to affect performance and availability, potentially impacting planned progress of the fusion ignition program. The team is embarking on a large-scale refurbishment of systems to mitigate this threat. Our robust maintenance program will ensure NIF can capitalize on ignition and push the facility to even greater achievements. This paper will describe the processes, procedures, and metrics used to plan, coordinate, and perform controls hardware maintenance at NIF.

Accelerators and other big science facilities rely heavily on internally developed technologies, including control system software. Much of it can and is shared between labs, like the Tango Controls and EPICS. Then, some of it finds broad application outside science, like the famous World Wide Web. However, there are still a lot of duplicating efforts in the labs, and a lot of software has the potential to be applied in other areas. Increasing collaboration and involving private companies can help avoid redundant work. It can decrease the overall costs of laboratory development and operation. Having private industry involved in technology development also increases the chances of new applications. This can positively impact society, which means effective spending of public funds. The talk will be based on the results of a survey looking at how much scientific institutes and companies focus on collaboration and dissemination in the field of software technologies. It will also include remarks based on the authors’ experiences in building an innovative ecosystem.

Enhanced Maintenance and Availability of Handling Equipment using IIoT Technologies

462

CERN, Meyrin, Switzerland

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. Partial access to some areas, a large area to cover, thousands of units, radiation, and diverse needs among handling equipment makes maintenance a cumbersome task. Without automatic monitoring solutions, the handling engineering team must conduct periodic on-site inspections to identify equipment in need of regulatory maintenance, leading to unnecessary inspections in hard-to-reach environments for underused equipment but also reliability risks for overused equipment between two technical visits. To overcome these challenges, a remote monitoring solution was introduced to extend the equipment lifetime and perform optimal maintenance. This paper describes the implementation of a remote monitoring solution integrating IIoT (Industrial Internet of Things) technologies with the existing CERN control infrastructure and frameworks for control systems (UNICOS and WinCC OA). At the present time, over 600 handling equipment units are being monitored successfully and this number will grow thanks to the scalability this solution offers.

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. This is mainly due to its complexity and the need for formal methods experts. At CERN, the PLCverif tool was developed to verify PLC programs formally. Although PLCverif hides most of the complexity of using formal methods and removes barriers to formally verifying PLC programs, engineers trying to verify their developments still encounter different obstacles. These challenges include the formalization of program specifications or the creation of formal models. This paper discusses how to overcome these obstacles by proposing a collaboration model that effectively allows the verification of critical PLC programs and promotes knowledge transfer between organizations. By providing a simpler and more accessible way to carry out formal verification, tools like PLCverif can play a crucial role in achieving this goal. The collaboration model splits the specification, development, and verification tasks between organizations. This approach is illustrated through a case study between GSI and CERN.

DALI Control System Considerations

547

HZDR, Dresden, Germany

The Dresden Advanced Light Infrastructure (DALI) is part of the German national Helmholtz Photon Science Roadmap. It will be a high-field source of intense terahertz radiation based on accelerated electrons and the successor of the Center for High-Power Radiation Sources (ELBE) operated at HZDR since 2002. In the current phase of DALI the conceptional design report is in preparation and there are ongoing considerations which control system to use best. We will present the status of those considerations, that include defining the requirements for the control system and a discussion of control system candidates. In the early conceptional phase we are still open to any control system that can fulfill our requirements. Besides pure technical performance, features and security the requirements encompass modernity, well established support by community and companies, long term availability as well as collaboration potential and benefit. To collect opinions from the community on what is the optimal control system we prepared a survey. Like that we would like to benefit as much as possible from the community experience with different types of control systems.

15 Years of the J-PARC Main Ring Control System Operation and Its Future Plan

639

S. Yamada
J-PARC, KEK & JAEA, Ibaraki-ken, Japan

The accelerator control system of the J-PARC MR started operation in 2008. Most of the components of the control computers, such as servers, disks, operation terminals, front-end computers and software, which were introduced during the construction phase, have gone through one or two generational changes in the last 15 years. Alongside, the policies for the operation of control computers have changed. This paper reviews the renewal of those components and discusses the philosophy behind the configuration and operational policy. It is also discusses the approach to matters that did not exist at the beginning of the project, such as virtualization or cyber security.

To control and monitor the plasma, ITER will use a number of different diagnostic systems, each with its own operating principle, and composed of different components. The systems will go through several design stages, and a unified systems engineering methodology is needed that will generate comparable design outputs for validation, integration and assembly of the systems. However, having the same methodology for such different systems means that it has to be general enough, such that the requirements of different systems are covered, the challenge being to find a compromise between the high-level approach and the final usability of the system design. The methodology needs to be such that sufficient input is provided to the developers and engineers in the successive phases, in an effort to minimize the risks in the development and integration phases. With the goal of addressing these challenges, a common systems engineering methodology for the design of ITER diagnostic systems was derived; Cosylab tested and validated this methodology by applying it to several diagnostic systems, and also identified and implemented improvements and developments to this methodology; lessons learned and observations made in the process of applying this methodology will allow systems engineers to gain a deeper insight into the relationship between systems engineering, architecture and design, and project management, in the domain of fusion-specific developments.

NECSA, Hartbeespoort, South Africa

Robotic and digitization risks refer to the potential negative consequences that can arise from the use of robots and digital technologies in various industries, which include experimental physics control systems. Risks include the compromising or malfunctioning of these systems, resulting in injury, equipment damage, loss of data or disruptions to critical infrastructure and services. Mitigating these risks involves taking proactive steps to reduce the likelihood of negative consequences and minimize their impact if they do occur. A comprehensive risk management approach that incorporates a combination of technical, organizational, and cultural strategies can help mitigate the potential risks through the implementation of the following strategies which will be discussed in this presentation: Regular maintenance and testing of robotic systems; Implementation of strong cyber security measures; Employee training and awareness programs; Adoption of industry standards and best practices; Developing contingency plans and backup systems; Establishing clear ethical and social guidelines.

Life Cycle Management and Reliability Analysis of Controls Hardware Using Operational Data From EAM

758

E. Fortescue, I. Kozsar, V. Schramm
CERN, Meyrin, Switzerland

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. The first part of the study involved the extraction, treatment and analysis of state-transition data to detect failures. The analysis was conducted using statistical methods, including failure-rate analysis and time-to-failure analysis to identify trends in equipment performance and plan for future obsolescence, upgrades and replacement strategies. The results of the analysis are available via a dynamic online dashboard. The second part of the study considers Front-End computers as repairable systems, composed of the previously studied non-repairable modules. The faults were recorded and analysed using the Accelerator Fault Tracking system. The study brought to light the need for high quality data, which led to improvements in the data recording process and refinement of the infrastructure team’s workflow. In the future, reliability analysis will become even more critical for ensuring the cost-effective and efficient operation of controls systems for accelerators. This study demonstrates the potential of EAM operational data to provide valuable insights into equipment reliability and inform decision-making for repairable and non-repairable systems.
