11. WIC (Warm magnet Interlock Controller) layout
Standardized interlock system for normal conducting magnets based on PLC:
Collects inputs from thermo-switches, flow switches and internal PC faults
Then gives the Power Permit to the power converter
No Beam Dump
at HIE-ISOLDE

12. The program running in the WIC is extremely simple
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)
IF (Magnet Overheats) OR (Flow Switch opens) OR (PC Status failure)THEN [According to the Configuration file] send Beam Dump signal

13. WIC design for HIE-ISOLDE
HIE-ISOLDE will be built in 3 stages
The hardware (PLCs + Patch panels) is designed to cover the 3 phases
1st WIC to protect REX-ISOLDE + XT00 line
2nd WIC to protect XT01, XT02, XT03 experimental lines
All control cables (Magnets + PCs) are already pulled for the 3 stages
Modification between phases managed by software only:
Will involved a full re-commissioning at each stage.
Number of elements to connect:
Existing (Rex-Isolde):
Existing power converters
1 dipole 1
20 quadrupoles
1 steerer (H/V) 2
New magnets
New Power converters
7 dipoles
(S500)
32 quadrupoles
34 (Cobalt)
23 steerers (H/V)
53 (Cancun)

15. Modification of the software part
First version of the generic code (for safety PLCs) was written for the LHC
Experiences in the SPS and the Booster showed the need for more flexibility
Decouple the Beam Dump and Fast Abort signal generation
Reduce our dependence on BE/CO
Before: WIC projects data not entered directly by us in a private DB  Not linked to Layout DB 
Before: SQL scripts depending on CO support and difficult to maintain for the generation of config. files 
ECR circulated to explain the reasons for the changes & impact on each machine & mitigations plans:
LHC, SPS, Linac 4, LEIR, Linac 3

16. The software part (2/2)
HIE-ISOLDE project: Guinea pig to test: Major changes in the generic code of the PLC
New process of generation of config. files for the PLC and WinCC software
WinCC config file

PLC generic code:
- 2 independent matrices
- Increase of size of the matrices
11x -> 12x 8 DO modules
WinCC generic code
New «Lock» feature
New color code (orange = passivation)
Adapt to the modifications in the PLC code
Java scripts
Data recorded in Controls DB
First use of java scripts to generate config files
First use of WIC editor
5 months of thorough & iterative tests with EN/ICE
Transition very well prepared well ahead of time by Ivan (with BE/CO) to define the DB structure, the WIC Editor and writing the Java scripts

18. Documentation Work Package Description (WPD) approved on EDMS
Second version in preparation
Commissioning procedure was co-written between the main stakeholders
MPE, EPC and MSC
A SharePoint website was put in place for the follow-up of the commissioning steps for each circuit.

19. Future project?
Studies on-going to build a storage ring (TSR)
New building for TSR machine : 670
33.27 m
26 m
Building 508
B 170

20. Conclusions I was involved at a very early stage in the project
Numerous advantages: Apply LHC standards, optimization of (cabling) costs, rack reservation, cable pulling secured, integration of our interlock boxes etc...
Drawback: Many iterations of the layout design.
All deliverables installed in February 2015… on time for the HWC
Very high motivation in the teams involved in the project (# renovation project)
Coordination and installation went smoothly
Several issues found on the ‘old’ Rex-Isolde magnets: Responsibility of MSC.
Phase 1 of the project will be finished (for us) by end of June 2015
Physics foreseen for October 2015 

23. 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.

24. Type of Interlock boxes used at HIE-ISOLDE
1-channel - Interlock Box: Dipoles, Quads
1x Thermo-switch + 1x Remote test
2-channels - Interlock Box: Steerers (H/V)
2x Thermo-switches + 2x Remote test
4-channels - Interlock Box: Triplets, Doublet
3x Thermo-switches
+ 1x Flow switch
+ 4x Remote test
New design for Hie-Isolde
