2. 2 BROOKHAVEN SCIENCE ASSOCIATES Requirements Provide information to the operator without knowledge of the PV names Provide displays of information that covers functional subsystems such as vacuum, temperatures, beam position, state of health. Provide the data in a meaningful order.

But – the Naming Standard has to be good - and what about additional information

5. 5 BROOKHAVEN SCIENCE ASSOCIATES Final Comments This idea is not new. Operators continue to recreate this sort of functionality. Sasha presented such an application for beam loss monitors. This should be a straight forward extension to IRMIS. Most of this information is already planned. A minimum number of PVData structures should support this. PVData is being supported over Channel Access V3 as well as JCA so the network communication should come free. A set of applications for tables, bar charts, and waterfall plots are planned.
