FBDK [FBRT] [Design Patterns]

Features

• Line numbers have been added to text panes to facilitate navigation.
• A Java tab has been added to the editor.
  • Generated Java® code is now updated every time the XML code is updated (or parsed after manual editing).
  • The Java code can be navigated from the navigation tree and worksheet.
• A JUnit tab has been added to the editor. This tab contains generated JUnit code for testing the corresponding code under the Java tab; however, the testing framework is not yet ready for release.
• A Log tab has been added to the editor, so you no longer need to look in a separate window to view log events, for instance when compiling a class or launching a system configuration.
• File Save As Java now creates backups for both .java and .class files, and saves them to subdirectories of separate java and lib folders, respectively.
• File Save As HTML now records pane split positions for improved documentation appearance with an updated version of the FBViewer applet. Also, the updated applet now contains its own Help button, so that the HTML generator no longer needs to create this link.
• A status indicator now appears at the right-hand end of the Status Line when lengthy operations such as File Save As Java are in progress.
• Links to examples based on the classic FLASHER4 and LED_HMI FB types have been added to the How To pages for Basic and Composite FB types and System Configurations, and to the Tagged Data methodology.
• Additional documentation is now generated with the Java code for data types (*.dtp).
• A drawingStyle preference has been added to the Preferences dialog and the editor.ini file.
• The Help menu items now link to on-line documentation instead of local files; this provides continuous access to the most current documentation and eliminates the need to bundle documentation with the FBDK download.
• Enumerated inputs are now presented as drop-down lists when testing FB types.
• A new Applications node is now available in the navigation tree of System diagrams, to facilitate creation and navigation among Applications.
• Tool support for Mapping has been improved.
• The FBDK now supports only the upcoming IEC 61499-1, 2^nd Edition event[guard] notation for display of transition conditions.
  NOTE - This will require the re-writing of transition conditions in any XML files in which they are used.
• The display of transition priorities in curly brackets {} is now supported.
• Additional documentation of transition priorities is now available.
• An Algorithms node has been added to the Navigation tree to centralize the adding, editing and deleting of Algorithms.
• The FBDK now supports the upcoming IEC 61499, 2^nd Edition SegmentType library element. Support for network Segments in System configurations has been updated accordingly.
• The Run button for remote devices in system configurations is now located on the pop-up menu for each device, enabling quick local start-up of the device without a separate dialog.
• A Service Sequence can now be added to to a Service via the pop-up menu for the Service in the Navigation tree.
• In anticipation of upcoming changes in IEC 61499-1 and -2, 2^nd Edition, a Service can now be included with any FB or Adapter type (not just SIFBs).
• The FBDK now supports user-defined function templates.

Bug fixes

• File Save As HTML now generates correct linkages to the FBViewer applet.
• Fixed a small bug that was causing errors when launching a test window on FBs that use generic ARRAY I/O, such as IN_ARRAY and OUT_ARRAY
• Scrolling of text panes to the corresponding text (when possible) when an element is selected in the Navigation Tree or the Worksheet now works more uniformly and reliably.
• Generation of Java code for array types has been corrected and tested.
• Generation of 61499 source (src) code for LD algorithms now works correctly by replacing "!" with "NOT".
• A bug that caused diagrams to close after creating a new Resource or network Segment has been fixed.
• All editing operations on variables in Structured Data Types now work identically to operations on input variables of FB types.

Other Changes

• JUnit testing of the core data model and code generation framework has been completed, and the editor has been extensively refactored for maintainability, in order to provide increased reliability, robustness, and reduced cycle times for future releases.
• A new map.ini file, containing a cross-reference of library element names to file locations, is now located in the FBDK root directory. This file is used by the FBDK to accelerate loading of library elements when needed, and is generated and maintained automatically by the FBDK.
• The Edit menu has been replaced with a Find/Replace button; editing operations on text panes are done with normal keystrokes/keychords.
• The Apply Tag button has been removed from the menu bar; this operation is now performed directly from the Tags table. See the Tagged Data Design Pattern for details.
• Small simplifications have been made in the dialogs for adding and editing elements, and corresponding documentation has been updated accordingly.
• The Alt+Del keychord is no longer used to remove a graphic element from its diagram; this is now done exclusively via the Delete item of the element's pop-up menu, to avoid accidental deletion of data in an active text pane.
• The Font item on the Worksheet popup has been re-labeled Scale, since that is the only function this item now serves.
• The Redraw item has been removed from the Worksheet popup, since it requires too much care in use to avoid unanticipated loss of information.
• The browser preference has been removed from the Preferences dialog and the editor.ini file; the FBDK now automatically uses the system's default browser.
• To avoid ambiguities in run-time type resolution, the connection of an output of the generic ANY type to more than one destination is no longer supported by the FBDK.
• For testability and robustness, the FBDK now uses regular expressions for conversion of ST algorithms to Java. This imposes a number of new limitations on ST syntax.
• The - Interface - node has been removed from the Navigation tree (library element interfaces can be edited whenever they are visible in the Worksheet); other labels have been simplified; and the Navigation tree font has been changed to plain sans-serif for better readability on LCD displays.
• 3- and 5-segment connections are now auto-routed when drawn or when FB instances are dragged; menu items for switching between 3 and 5 segments are no longer used.
• No checking is done when the File Save dialog is invoked; the contents of the tabbed text panes are saved "as is".

FBRT [FBDK] [Design Patterns]

Features

• Connection optimizations have produced an approximately 50% reduction in event propagation overhead and call stack size for event inputs of composite FBs.
• The operational state machine in Figure 24 of IEC 61499-1 is now fully implemented and tested.
• Multi-threading overhead has been reduced by centralizing in the Resource the scheduling of the timing service interfaces E_DELAY, E_CYCLE, E_TRAIN, E_TABLE, and E_N_TABLE.
• New convenience classes have been added: RADIO_N, IN_ANY_LBL, IN_ARRAY_LBL, E_DEMUX8, ...
• SAMPLE_xxx, E_SEL_xxx, FB_MUX_xxx and FB_SEL_xxx FB types are now provided for all data types (xxx), including the MATRIX type.
• The FB_SEL_ARRAY type has been deleted. ARRAY is not a data type in IEC 61131-3, and this block was never used in previous versions of the FBDK.
• A REQ input has been added to FB_LABEL to provide dynamic updating of the label text.
• RADIO_BOOL now allows changing of labels (but not output state) upon re-initialization.
• The format for the LBLS input of the XSPACE element has now been simplified: a WSTRING containing a comma-separated list of labels is now used instead of an ARRAY of WSTRING.
• A simplified, documented SPINNER control is now available.
• The BCD conversion blocks FB_INT_TO_BCD_WORD and FB_WORD_BCD_TO_INT have been simplified and documented.

Bug fixes

• E_TRAIN has been updated for compliance with IEC 61499-1, Table A.1#10. Previously compiled FB types and older system configurations that used the value of the E_TRAIN.CV output will not work correctly with the new version. The older, incorrect version ran the value of the CV output over the range {0..N-1}; the new, correct range is {1..N}.
• A bug that prevented connecting to data inputs of composite FBs that also had adapter interfaces has been fixed.

Other Changes

• Run-time checking of data connections has been improved to give more consistent error messages.
• The obsolete AI_SCALE,AO_SCALE,FB_SLIDERL and FB_SLIDERLR classes have been deleted.
• JUnit testing of all runtime classes is completed.

Design Patterns [FBDK] [FBRT]

Features

• MVCD
  • VDIR and XYHOME data types have been introduced to provide the same level of clarity to component orientation as VSTYLE for workpiece rendering.
  • The DIR input of XY_VIEW and XY_VIEWL has been changed to an instance of the new XYHOME type for clarity of expression.
• Matrix Framework
  • New documentation is now linked to the Design Patterns home page.
  • The MATRIX data type has been re-implemented and optimized for column operations. Previously created function blocks operating on this type may not work correctly, and may have to be re-implemented using the information provided in the Java documentation for the MATRIX class.
• Process Control
  • Image quality of View elements such as PUMP_VIEW, PIPE_VIEW and SHAFT_VIEW has been improved through the use of Java2D rendering.
  • Bumpless Transfer and Anti-Reset Windup features have been corrected and tested for the FB_PIDR type.
  • TANK_MDL has been updated to a lightweight, clock-driven version instead of using a separate thread. TANK_MVL, TANK_MVCL and TANK_MVCR have been updated accordingly.
  • The PV and XOUT inputs of FACEPLATE have been changed to UINT; REAL resolution is not required for simple bar displays. TANK_VIEWL, TANK_MVL, TANK_MVCL and TANK_MVCR have been updated accordingly.
  • The DX parameter of the STRIP3 and STRIP4 strip-chart recorders has been changed to N (number of x-increments) for scalability.

Bug fixes

• Tool support for the Tagged Data pattern now works correctly with instances of IN_ANY, IN_ANY_LBL, OUT_ANY, IN_ARRAY, IN_ARRAY_LBL, OUT_ARRAY, and IN_ENUM.
