Need for cf-update How to add new channels – Without having to learn the client api’s How to manage existing channels – Orphaned channels – Moved channels Automatically handle some attributes/properties of channels – hostName – iocName

cf-update v2.0.0 The properties currently managed with cf- update – hostName – iocName – pvStatus : Active or InActive – time : The last time the above properties where updated

Example st.cmd iocInit dbl > record.dbl system “cp records.dbl /cf- update/$HOSTNAME.$IOCNAME.dbl”

Under the Hood The cf_monitor daemon monitors $(CF_UPDATE_DIR) directory and envokes an updare task when – A new *.dbl file is created in the dir – An existing *.dbl file is modified The update task handles – Uses the filename to obtain the hostName, iocName property values and defines time as the time when the file was modified – New channels – creates new channels with hostName, iocName properties – Orphaned channels – the hostName, iocName properties are retained for debugging purpose but the pvStatus is set to inactive – Moved channels – ensures that the hostName, iocName properties are update when channels are moved – Unchanged channels All other existing properties and tags are left unaffected

Physics applications The High level applications tend to prefer a hierarchical view of the control system where they can group channels by type (such as BPM, horizontal corrector) or location accelerator physics high level application APHLA (python) ChannelViewer Channel line plot Waterfall plot Channel Orchestrator

Future plans Manage additional properties and tags automatically – Integration with NameService/NameValidator Replace channel widgets with general purpose widgets using pvmanager services and formula Integration with MASAR
