Outline

Status of control and DAQ systems for SC cable and magnet measurements

Maintenance plan (to keep present functionality) Development plan (to comply with new

requirements and assure long term functionality)


Range of systems

Fixed test systems – SM18, Block 4, B163 Mobile systems – SM18, Cryolab (B165)

Not covered: systems for warm measurement such as for the Magnet Rescue Facility in B180, B181 and MQW in B867.

Risk analysis of meas. systems


Concern Problem Impact Prob Wght

LabVIEW on Solaris

Discontinued 5 years ago. But so far it keeps working.

High Low 3

Solaris No longer supported at CERN since 1 year. High Low 3

SBS34 Discontinued 4 years ago. Porting to another module requires difficult work.

Medium High 6

BAB740 Discontinued 4 years ago. BAB760 is produced and could replace the BAB740 with some work.

Medium High 6

VME 30 years old standard. Becoming obsolete. Produced by few companies. Expensive.

Reasons to adopt PXI Industry standard for instrumentation, based on PCI Supported by 60 vendors, commercialising >1000 modules PXI is 10 years old Smaller, cheaper than VME Key hardware features: triggering and synchronisation, shielding,

speed (PXI-express, follows PCI express development) Key software features by National Instruments: LabVIEW, LabVIEW

Real Time, integrated network communication, drivers Key OS features: Pharlap, VX-Works, Windows, Linux Connects to VME, which allows partial migration, keeping VME

investment where needed


Maintaining present systems Step 1: Replace Sun with PXI, keep MXI-VME Advantages:

Up to date LabVIEW version Up to date OS (no Solaris)

Disadvantage: VME processors, modules and crates are kept (some

are obsolete)


Upgrade plan Step 2: Replace VME with PXI

More compact, higher density modules 3 VME crates with 56 modules Replace 5 VME ADC with 1 PXI ADC

Higher performance ADCs Higher precision, up to 24 bit ADCs and 7 ½ digits DVMs Faster acquisition, if needed

Maintenance advantages: No SBS, BAB, VME, MXI

Disadvantage: higher cost

Replacement of all Sun based systems

All Sun based measurement systems will need to be replaced (B180 Magnet Rescue Facility, B181, B867, …)

Not part of the SC laboratory review, but to be kept in mind

My inventory has 90 Sun workstations


Recommendation Plan 1: maintenance.

Replace all Sun measurement stations with PXI processors, keeping the VME crates and modules.

Plan 2: upgrade. Develop one pilot DAQ system in PXI for validation. Replace all DAQ systems with PXI system.

B163 Plan 1: maintenance, replace Sun workstations. Plan 2: replace DVMs with PXI if needed for higher speed.

B165 Can be maintained as is (no Sun workstations) For new measurement systems PXI should be considered.
