2. TE-MPE-TM 09/08/2012, TE-MPE-MS section WIC (Warm magnet Interlock Controller) layout Standardized interlock system for normal conducting magnets based on SIEMENS PLC (Programmable Logic Controllers): –Collects inputs from thermo-switches, flow switches, PC faults… –Then gives the Power Permit to the power converter + Beam Permit to BIS (LHC) Configuration DB

3. TE-MPE-TM 09/08/2012, TE-MPE-MS section WIC principle The Warm magnet Interlock Controller is a PLC based system, using deported I/O crates (connected via Profibus). The Siemens “F” (F stands for Fail safe) Series PLC is used, offering a self checking safety environment and programming through ‘Safety Matrix’. We use generic SW and (to some extent) HW for all our installation, to allow for efficient and resource optimized installation, commissioning and operation. The program running in the WIC is extremely simple IF (Magnet Overheats) OR (Flow Switch opens) THEN [According to the Configuration file] Switch-off the relevant PC(s) 3

4. TE-MPE-TM 09/08/2012, TE-MPE-MS section Interlock boxes Interlock boxes are placed on or close to each magnet to collect all input signals. For maintenance purpose, a remote test feature is implemented (by means of a relay) in order to simulate the opening of any input signal. This operation can be done remotely and allow us to check periodically the installation during shutdowns.

7. TE-MPE-TM 09/08/2012, TE-MPE-MS section PLC & PVSS programming The programming of the PLC is done in collaboration with EN/ICE-PLC. The Programming of the PVSS supervision is done in collaboration with EN/ICE- SCD. The advantages of having a supervision: o On line status of the full installation (Magnets & PCs). o Communication statuses: Ethernet and Profibus. o Full diagnostic with exact location of faults o Archiving of all faults (History Buffer) in SCADA + LHC Logging o Full integration in DIAMON + LASER (Alarm system) o Allows remote operation, supervision and testing of the installation o We receive a warning message in case of problems on one of the PLC power supplies (true redundancy). 7

11. TE-MPE-TM 09/08/2012, TE-MPE-MS section 11 BOOSTER Project Due to the configuration file in which we cannot exceed 20 input modules (=480I) and 80 output for the Power-converters, we have to use 4 PLC to control all the magnets and the 177 Power-Converters: -PLC1 with 16 Deported units CIWRA_11 to CIWRA_116 for the main magnets inputs which control 3 Power-Converters. -PLC2 with 16 Deported units CIWRA_21 to CIWRA_216 for the 1 st Multipoles which control 22 Power-Converters. -PLC3 with 6 Deported units CIWRA_33 to CIWRA_316 for the 2nd Multipoles which control 72 Power-Converters. -PLC4 with 5 Deported units CIWRA_42 to CIWRA_412 for the 3nd Multipoles which control 80 Power-Converters.  174 interlock boxes will be installed on the magnets to collect the signals from thermo-switches as well as to carry out the remote tests.

16. TE-MPE-TM 09/08/2012, TE-MPE-MS section PS project Officially still under the responsibility of EN-MEF-INJ. o But R. Brown is leaving for retirement in Feb. 2013, TE-MPE + TE-MSC to take over responsibility thereafter (Memo to be written) R. Brown gave us a visit of the installation in Bldg. 355 & Bld. 365 on 29.03.2012. o Conclusion of the visit: Last consolidation was done in 1994. There are enough spares for the correctors, but the spare crate for the mains was cannibalised! Our priority is to re-cable and test this spare crate o We found all missing components. o The drawing for the cabling that we have is not up to date! It does not include modifications done after TE-EPC exchanged the main power supply (POPS). Action foreseen during next TS. During LS1, some refurbishment of the installation will require some modification to the existing installation! o Mainly to remove interlock switches on some cabinets that will be removed. No WIC deployment/renovation is foreseen for the PS for the LS1 period, but will be discussed for LS2. 16

17. TE-MPE-TM 09/08/2012, TE-MPE-MS section Other projects Ti2-Ti8-TT40: o Consolidation of existing system by adding remote testing feature (some 900 magnet interlock boxes to be modified + 40 remote I/O crates!) ELENA: o Not started as postponed by 1 year (2016?), plan is still to finalise the design this year. Block4, SM18, FRESCA: o Not started, no date for completion yet o Time frame to be agreed with QPS plans, probably between LS1 and LS2? S-FRS magnet test facility (Bldg. 180): o Not started, no date for completion yet o Time frame to be agreed with QPS plans, probably between LS1 and LS2? North zone consolidation project? o Big project (400 magnets & PCs)! o Nothing decided yet, pre-study for early 2013, then project and budget to be approved o Time frame >=LS2 Other projects + SPS renovation: See Yan’s presentation! + SPS renovation: See Yan’s presentation!
