	The ATLAS (LHC detector) Liquid Argon Calorimeter is classified as a critical cryogenic system due to its requirement for uninterrupted operation. The system has been in continuous nominal operation since the start-up of the LHC, operating with very high reliability and availability. Over this period, control system maintenance was focused on the most critical hardware and software interventions, without direct impact on the process control system. Consequently, after several years of steady state operation, the process control system became obsolete (reached End of Life), requiring complex support and without the possibility of further improvements. This led to a detailed review towards a complete upgrade of the PLC hardware and process control software. To ensure uninterrupted operation, longer equipment lifecycle, and further system maintainability, the latest technology was chosen. This paper presents the methodology used for the process control system upgrade during development and testing phases, as well as the experience gained during deployment. It details the architecture of the new system based on a redundant (Hot Standby) PLC solution, the quality assurance protocol used during the hardware validation and software testing phases, and the deployment procedure.

	The software engineering of process control system for CERN cryogenic installations is based on an automatic code production methodology and continuous integration practice. This solution was initially developed for the LHC Accelerator applications, then adapted to LHC Detectors, test facilities and non-LHC cryogenic facilities. Over the years, this approach allowed the successful implementation of many control system upgrades, as well as the development of new applications while improving quality assurance and minimizing manpower resources. The overall complexity of automatic software production chains, their challenging maintenance, deviation between software production methods for different cryogenic domains and frequent evolution of CERN frameworks led to the system’s complete review. A new unified software production system was designed for all cryogenic domains and industrial technologies used. All previously employed frameworks, tools, libraries, code templates were classified, homogenized and implemented as common submodules, while projects specific configuration were grouped in custom application files. This publication presents the new unified software production solution, benefits from shared methodology between different cryogenics domains, as well as a summary of two years of experience with several cryogenic applications from different PLCs technologies.
