Classes and Functionalities

edu.stanford.slac.mps.epics.ControlSystem

• Monitors current Macro state numbers from IOC:BSY0:MP01:TTBLST.VALA
• Bypasses faults to a value for a time duration
• bypassed faults and end times
• Given a fault name, gets current state, type, and timestamp
  of the fault
• Given a PV, gets beam rate names (MPS and actual)
• Translates between EPICS and Java time

edu.stanford.slac.mps.jdbc.JDBCMonitor

• Loads all data from Config/Logic DB
  • JDBC url for Config DB URL prefix: jdbc:sqlite:/usr/local/lcls/epics/iocTop/MachineProtection/mpsConfiguration/database/current_version/mpsdb.sqlite3 current_version is stored in PV IOC:BSY0:MP01:DBVERSJDBC url for
  • Logic DB URL prefix: jdbc:sqlite:/usr/local/lcls/epics/iocTop/MachineProtection/mpsConfiguration/database/current_version/mpsdb.sqlite3 algorithm/
• Checks periodically for new versions
  • Current Config DB version is stored in IOC:BSY0:MP01:DBVERS
  • Current Logic DB current_ version is stored in PV IOC:BSY0:MP01:ALGRNAME
  • Checks periodically for new versions
• Monitors current Macro states

edu.stanford.slac.mps.jdbc.config.ConfigDB

• Singleton
• Serves as a facade to information about faults

edu.stanford.slac.mps.jdbc.logic.LogicDB

• Singleton
• Serves as a facade to information about Macros (and states), ignoring Macros, current MacroStates
