2. PHELIX in 2012 Beamtime: Shot statistics: only 10% downtime
68% of the time related to experiments (total 18:
Z6, PLH, xRay-Lab)
rest: internal
Shot statistics:
3556 shots in total
80 failures (2,2%)
2365 experiment shots
27 failures (1,1%)

3. The PCS: Facts and Numbers
OS: Windows XP
LabVIEW 2009
CS-V3.21
running on 23 nodes
(20 PCS, 1 developer, and
2 hardware test nodes)
25 executables (four types)
70 PHELIX classes
about 350 instances
about process variables
the PCS is (still) one of the largest CS applications

11. Latest News: Getting rid of the DSC-Engine
Status: PHELIX uses old DSC engine (LV 7.1) for Beckhoff
Problem: SIEMENS OPC Server is not running with modern DSC-Engine
Solution: direct connection to Beckhoff (ADS DLL)
Hardware: BK9050 (twisted pair)
Software: New class
