Device Server machine
 Windows
2000 machine with LonWorks
interface card.
 Each device server started with own
batch script
 local copy of dll-s and configuration
database maintained with CVS
 remote access with VNC

ACS device servers at ANKA
 ACS
version 1.1 ported to windows
because of LonWorks drivers
 We had to do some fixes on BACI
properties, should they go in main ACS
branch?
 Some problems:
– with large number of slow clients monitor
dispatching starts to be “slower”
– logging server is synchronous and slows
down whole system when used

Upgrade to newer ACS?
 Are
mentioned problems solved in new
ACS?
 What are new features, that ANKA
would benefit of?
 How much does it take to port ACS to
Windows?
