  2. Block Diagram

  3. BSAC Facility Initialization • Init BSAC EPICS Facility States • Init BSAC EPICS Facility Constants • Init SLC Thread Data Collection Structure

  4. bsacAsync Thread

  5. Init SLC Thread Data Collection Structure

  6. SCP Request Message (bsacHdlr)

  7. Measdef Setup • Dbput to EPICS Facility MDEF Records • Setup Data Reply Collection Structure • Dbput to EPICS Facility “GO$MD” record SCAN=IO_INTR, for every device, every unit participating in this measdef • Store MDEF timeout value for bsacAsync
