Monitor and control integrated with DCS
• Joint Controls Project team at CERN provides
hardware and software support for CAN bus
• Client/server interface to the official SCADA,
PVSS II, to be done by DUBNA collaborators
Engineering
• Development platform for CAN is LabView
• Principal challenge is implementing the
functional block diagram using radiation
tolerant COTS – the design may not be as
simple and elegant as it could be otherwise
• Prototype milestone is July 2001
