Setup
Environment
- Effectively, you can only develop MPSGui inside Eclipse on lcls-builder.
- Check out the CVS module physics/mps/mpsgui into your workspace
- From now on, the root of project is referred to as $MPSGUI_ROOT
- You can use eco to checkout the package. The name of the module is mpsgui.
- Run ant to build the mpsgui and mpscud jar files.
- The mpsgui and mpscud scripts should use the jar files built in the jar folder.
Dependencies
For library paths, see the scripts $MPSGUI_ROOT/mpsgui or $MPSGUI_ROOT/mpscudbuild.xml file. Note that the dependent jar files are copied into the lib folder and are part of CVS. To update the jar files, run ant update_dependencies. This should copy the files from $PHYSICS_TOP on dev onto the lib folder. You can then commit these updated dependent jar files into CVS.
- ezJCA (version R0-0-10)
- javainterfaces (current version)
- MPS Config(current version)
- Oracle JDBC driver
- Sqlite JDBC driver
- SwingUtil (current version)
- jgoodies.jar can be added at runtime for the Matlab look & feel
- xal4lcls
- ext.jar (current version)
- xal.jar (current version)
Run inside Eclipse
...
Test
- Test using the mpsgui and mpscud scripts from the command line. This sets the Oracle Wallet environment variable and other EPICS variables.
Development
Major Recurring Tasks
- Previously, one had to check the live history in the MPS GUI HistoryViewer (and if empty, restart the MPS History Server). However, now there is a CRON job that monitors this and will trigger alarms for the operators
Tips
- Find the Java field that contains the UI component that prompted your development (change the back-/foreground color, if not sure); then use Eclipse References (right-click menu) to find where the field is being used
Overview
Launch Scripts
mpsgui
- Located under $MPSGUI_ROOT, must be executable (chmod +x)
- Sets up the ORACLE Wallet and the log file
- Launches MPSGui using Plastic3DLookAndFeel from jgoodies
- byenti is a legacy system property that tells MPSGui to interpret bypass end times as absolute (or, if false, relative) times
mpscud
- Located under $MPSGUI_ROOT, must be executable (chmod +x)
- Sets up the Oracle Wallet and the log file
- Launches MPSGui in CUD mode using Plastic3DLookAndFeel from jgoodies
- Operators and Mike Z know details about the CUD mode
- byenti is a legacy system property that tells MPSGui to interpret bypass end times as absolute (or, if false, relative) times
Classes and Functions
User Interface
- The main user interface consists of 5 tabs: Summary, Faults, Logic, Ignore Logic, and History
- Each tab has a corresponding package under edu.stanford.slac.mpsgui.ui
- Classes in those packages are complex Swing components (mostly, JPanels and JTables)
- Each XYZPanel class under edu.stanford.slac.mpsgui.ui is a subclass of edu.stanford.slac.mpsgui.ui.AbstractPanel
- (Almost) every widget of the panel is stored in a field in the corresponding XYZPanel class, where XYZ is a descriptive string that explains what the panel shows
- The fields are public to allow registration of the listeners (however, it doesn't make sense to set them)
edu.stanford.slac.mpsgui.ui.AbstractPanel
- The root of all MpsGui XYZPanel classes
- Defines how widgets are created/added to its subclass
edu.stanford.slac.mpsgui.ui.MacroDetailsPanel
- Shows the details of a Macro

edu.stanford.slac.mpsgui.ui.MpsGuiPanel
- The main panel that is added to the JFrame
- Contain a JTabbedPane as the immediate child
edu.stanford.slac.mpsgui.ui.MpsGuiTable
- The root of all MpsGui XYZTable classes
- Features a TableSorter (see SwingUtil) and alternating background colors for rows
edu.stanford.slac.mpsgui.ui.SliderCachePanel
- Allows user to select a cached state
edu.stanford.slac.mpsgui.ui.edm.EDMPanel
- Not used anymore
edu.stanford.slac.mpsgui.ui.fault.AbstractFaultPanel

edu.stanford.slac.mpsgui.ui.fault.CurrentFaultsPanel
- Not used anymore
edu.stanford.slac.mpsgui.ui.fault.EPICS/LinkNodeChannel/LinkNode/LinkProcessorFaultPanel
- Shows information specific to each fault type
edu.stanford.slac.mpsgui
...
- Go to Run in the Window menu
- Select "Open Run Dialog..."
- Select "MpsGuiLauncher" in the window on the left

- Enter the following arguments:
in the "Program arguments" area.Code Block jdbc:sqlite:/usr/local/lcls/epics/iocTop/MachineProtection/mpsConfiguration/database/ jdbc:sqlite:/usr/local/lcls/epics/iocTop/MachineProtection/mpsConfiguration/algorithm/ jdbc:oracle:thin:MPS_HISTORY/*current_password*@mccqa.slac.stanford.edu:1521:MCCQA
- Replace current_password with the current password (can be found in the $MPSGUI_ROOT/mpsgui script)
- Press "Run"
.ui.fault.MainFaultPanel
- Features a tree-like browser for faults and a placeholder for the detailed information
edu.stanford.slac.mpsgui.ui.logic.StatesCorePanel

- Periodically checks for new MPS History messages
- If the live history panel is empty, please trouble-shoot the MPS History Server
- Features a panel for an interactive search of the MPS history
- Filter applies to fault names only
- Launches new search on "key typed", tries to cancel the previous search (may break in the future)
edu.stanford.slac.mpsgui.controller.ignorelogic.IgnoreLogicViewer
- Controller for the "Ignore Logic" tab
- Monitors the state of ignoring macros (using MPS Config)
- Caches previous states
- Shows detailed information about ignoring and ignored macros
To test, ignore/unignore macros by writing 0 or 1 to YAGS:IN20:211:IN_LMTSW_BYPV

New States
- If the truth table's state can't be found in the Logic DB, make an alert panel that shows the truth table's name, the raw state value from the IOC:BSY0:MP01:TTBLST array, and a message saying "Send the above information to the controls group."
- Documentation
- Highlight new truth table state when selected

- Note that the mpsgui script redirects all logs to files elsewhere. During development and testing, it is often fruitful to have the logs on the console.
