1. Instrument Control Systems Seminar 2014, 20 th -24 th October 2014 New Standards VLT Control HW System

2. Instrument Control System Seminar, 20 th -24 th October 2014 Outlook  Introduction  Obsolescence management  New HW standards  What has changed  What has not changed  Compliance Engineering  Summary

3. Instrument Control System Seminar, 20 th -24 th October 2014 Obsolescence management strategy (1)  Actual VLT HW based on VME boards  VME bus is an international standard but !  Huge coupling between HW and SW  Typical example MACCON board  SW drivers build around the board (MCM)  Difficult to replace  virtualization

4. Instrument Control System Seminar, 20 th -24 th October 2014 Obsolescence management strategy (2)  So what can we do to avoid those problems?  Interfaces with upper level based on Ethernet  Interface with HW world based on industrial stds  0-24V, ±10V, RS485, etc  Drivers development on provider side  Based on open stds (OPC-UA, PlcOpen, etc)  Obsolescence is now handled at function level and not anymore at board level

5. Instrument Control System Seminar, 20 th -24 th October 2014 New HW standards What has changed  Due to the diversity of requirements we have selected two different solutions based on PLC.  ICS application  BECKHOFF world  Safety and Cryo Applications  SIEMENS  Time system  moved to IEEE1588  Already available at Paranal  Fully deployed on UT2 (other UT on demand)  Technical CCD moved to GigE vision Ethernet  This is true only for instruments not for UTs

6. Instrument Control System Seminar, 20 th -24 th October 2014 New HW standards What has not changed (1)  Cabinets has still to be cooled (~±1.5 deg)  PLC means different cooling problems  Less power but still enough to for problems  Embedded in smaller cabinets (more cabs)  Need to duplicate the cooling infrastructure  Not a bad idea to reduce the cabinets number !

7. Instrument Control System Seminar, 20 th -24 th October 2014 New HW standards What has not changed (1)  Available HVAC controllers for cabinets  ESO 1HE cooling Unit  Alternative PLC base HVAC (small cabinets)  Recommended 1HE, but PLC based allowed  We have to be and will be pragmatic !!!!  What does matter is coherence

8. Instrument Control System Seminar, 20 th -24 th October 2014 New HW standards What has not changed (2)  Cabinets have still to be wired properly  Cabinet connections are more complex/dense  Touch panels to be accessible (front Panel)  Cables entrance to cabinet (EMC)  Power management and safety

9. Instrument Control System Seminar, 20 th -24 th October 2014 New HW standards What has not changed (3)  PLC specific cabling problems  What we don’t want to see at all !!!

10. Instrument Control System Seminar, 20 th -24 th October 2014 Compliance Engineering  All Electronic equipment must be compliant with EU legislation  Reference general document for design:  GEN-SPE-ESO-50000-5401 Issue 3

11. Instrument Control System Seminar, 20 th -24 th October 2014 Compliance Engineering (1)  New VLT Electronic design document  Under verification/signature  Available end of October  Provides implementation examples  Product and system design rules  Architectural deployment example for PLC  List of recommended HW material

12. Instrument Control System Seminar, 20 th -24 th October 2014 Compliance Engineering (2)  What can we do to help you?

13. Instrument Control System Seminar, 20 th -24 th October 2014 Compliance Engineering (3)  Architectural view

14. Instrument Control System Seminar, 20 th -24 th October 2014 Compliance Engineering (4)  List of recommended PLC Modules doc  Under signature too (available end of the week)

15. Instrument Control System Seminar, 20 th -24 th October 2014 Summary  Moving to PLC allows more flexibility  Easier obsolescence management  BUT:  Cabling, cooling, interconnections still needs care  EMC and CE compliancy can be a real issue  Mitigation  Schematics examples available  List of recommended modules available  Collaborative work with ESO
