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 10000 process variables
the PCS is (still) one of the largest CS
applications

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
