WIC (Warm magnet Interlock Controller) layout • Standard and generic interlock system for normal conducting magnets based on PLC: Collects inputs from thermo-switches, flow switches and internal PC faults – Allows/inhibits start of power converter and beam operation – MPE-TM 9/15/2020 Y. Bastian / C. Von Siebenthal 3 / 18

WIC (Warm magnet Interlock Controller) layout • Advantages • • Highly reliable system, long lifetime Generic HW and SW components, configured to specific application through Controls Config DB Already 32 PLCs/system in operation throughout the complex Challenges • • Most SIEMENS components are not (or only to a very limited extend) radiation tolerant, few remote I/O modules qualified for ~100 Gy for TL installations (TI 2, TI 8, …) Trade off between installation close to the machine (rad tolerant I/Os) and cabling cost (typically already 2/3 of renovation budget) MPE-TM 9/15/2020 Y. Bastian / C. Von Siebenthal 4 / 18

Aim of radiation test campaign • Architecture for new installations/renovations in the injector complex (e. g. PS) could be greatly simplified/ made cost efficient using a ‘low density’, radiation tolerant remote I/O solution • Easy to install on site/integrate with SIEMENS PLCs/Win. CC • Ideally configurable in order to provide one/few inputs and outputs per connector (magnet) MPE-TM 9/15/2020 PS radiation levels Y. Bastian / C. Von Siebenthal 5 / 18

SW implementation • Specific code base developed for radiation test (fast cycling and readback of I/Os for detection of SEUs in both logical states) • Used UNICOS framework for SCADA integration • UNICOS (UNified Industrial Control System) is a CERN-made framework to develop industrial control applications. It deals with the two upper layers of a classical control system: Supervision and Control. MPE-TM 9/15/2020 Y. Bastian / C. Von Siebenthal 13 / 18

Conclusions Test bed for radiation testing of alternative remote I/O modules nearing completion • Software stack developed based on UNICOS toolbox • Aiming at 2 ~one week test campaigns (June and July/August 2015) • If successful, alternative remote I/O modules would provide interesting option for resource and cost efficient renovation of injector chain • MPE-TM 9/15/2020 Y.
