2 BROOKHAVEN SCIENCE ASSOCIATES Outline Control System Architecture Relational Database Tools - IRMIS EPICS Extensions Control System Studio (CSS) Tools Conclusions

3 BROOKHAVEN SCIENCE ASSOCIATES EPICS V3 A narrow interface supports reusable clients DBR_ types included: –Double, long integer, enumerated, string –Metadata: time stamp, alarm severity, display and control Only monitored value, time stamp alarm severity This narrow interface supported signals well It is not easily extendible nor is it complete enough

4 BROOKHAVEN SCIENCE ASSOCIATES DBR_TYPES in EPICS V4 Easily extendible thanks to work done by Marty Kraimer and Matej Sekorania Can monitor metadata too – Only send structure elements that have changed New data types: Extend the DBR_TYPES to higher level applications Extra metadata needed to complete description of type Heavy basis on Aida (Greg White – SLAC), in discussion with NSLS II team from controls and phsyics, Timo Korhonen (PSI), and James Rowland (Diamond)

5 BROOKHAVEN SCIENCE ASSOCIATES Normative Types - Standard Support PV List: list of PV names and relative order Multi-Channel Array: synchronous array of PV List Image: image with information to allow actions Multi-dimensional arrays: 1 to N of same type Statistics: high, low, median, average, standard deviation, start time, end time, number of samples Histogram: Binned counts of one PV over time. Set: Many PVs at one point in time Sequence: One PV over a period of time Table: Columns of values with rows of instances. Ragged Table: Corba Any

15 BROOKHAVEN SCIENCE ASSOCIATES Conclusions Version 3 has provided adequate support for signal data for many years with a wide variety of clients developed against the interface. The need to extend the support for more complex data has been clear for near as many years as version 3 has existed. The approach to take use cases to extend the data types seems to be appropriate to find a minimum set of new data types that provide a wide range of functionality. The active engagement of many in our community to help define this set has been productive for physics applications. Reference middle layer services are written to integrate relational data, aggregated data, and computed data. A team of physicists and programmers at several labs are now focused on this effort with approaching deadlines A lot more work is needed.
