    2. January 22 2010 BACnet for EPICS : EPICS Elements EPICS Components Standard EPICS Build-system compatible Separate Support and Example Application packages EPICS EDM screens built by Web-based tool EPICS Runtime Databases built by Web-based Tool

    3. January 22 2010 BACnet for EPICS : EPICS Elements Basis of Operation bacnet4linux provides runtime export of data. IPC Message Queues Virtual File System (VFS) EPICS IOC (co-hosted with b4l) reads runtime data from b4l Initialize records from VFS IPC Message queues populated by COV monitors from BACnet Very efficient

    4. January 22 2010 BACnet for EPICS : EPICS Elements Installation, Support Unpack Support tarball to standard EPICS Support directory Edit configure/RELEASE Specify locations of required libraries cd to 'Top' make clean, make

    5. January 22 2010 BACnet for EPICS : EPICS Elements Installation, Application Unpack Application tarball to standard EPICS Application directory Edit configure/RELEASE Specify locations of required libraries cd to 'Top' make clean, make

    6. January 22 2010 BACnet for EPICS : EPICS Elements EPICS EDM Screens Created by Data Configuration Web Tool Uses EdlBuild Perl Library Default TRIUMF Look & Feel Substantially Customizable to local conventions

    7. January 22 2010 BACnet for EPICS : EPICS Elements EPICS EDM Screens Main menu with pull-down per Local Device May split devices with many child devices EDM limit on related-display callups Panel per Device Panel contains a grid of Objects Analog Objects contain Text-update widget Binary Objects contain LED
