4diac IDE

User Interface & Usability Enhancements

• New grid for all graphical editors that reduces visual clutter to improve focus on content
• Modernized look of Interface Editor:
  • Cleaner alignment of comments and data types
  • Connections follow type colors to be in line with Function Block Network editor
• Mapped Function Blocks are now shown with a device-colored bar at the bottom of the block
• Modernized look of ECC editor:
  • Color scheme adjusted to overall IEC 61499 colors (i.e. events and data connections)
  • Improved state representation with cleaner action lists
  • Smoother splines for transitions
• Added member access pins for all FB instances
• Added unified wizard to manage project libraries
• Removed Affected Types dialog when saving types
• Updated rules for hiding pins to prevent hiding of connected pins
  • Tables also reflect that option correctly now
• Added feature to reconnect Target Pins to different Source

New and changed validations

• An internal FB may not have the same name as a pin of the surrounding type or instance
• An internal FB in a Simple or Basic FB must be a Simple, Basic, or Service Interface FB
• Warn for unused FB and SubApp instances with no incoming event connections
• Validate additional cases of incompatible types with generic inputs or outputs
• Optionally validate multiple event output connections leading to undefined execution order
• Variables may now have the same name as a data type

ST Editor

• Remove ALGORITHM and METHOD blocks when saving algorithms in FB types for improved compatibility with other IEC 61499 tools
• Extract method refactoring now uses the exact selection
• Update ST code during copy refactoring

Plant Hierarchy

• Added reordering of Nodes and Folders
• Improved updating of Comments

Bulk Editor

• Fixed “Open in Bulk Editor” showing in unrelated context menus
• Added new context menu to go to selected element of the result table
• Added filtering of Internal Attributes in result table
• Fixed edge cases for Copy/Paste of result table
• Added validation when adding new Attributes

Deployment and Monitoring

• Show resource status in Debug view
• No longer watch internal FBs or variables by default
• Separated OPC UA deployment into its own optional feature
• Upgraded Eclipse Milo to version 1.1.2
• Type hash now only considers Negate and Retain attributes

Replay Debugging

• Exact reproduction of the run of an application is possible via the newly developed replay debugging feature
• Start the repoduction from:
  • existing traces generated from 4diac FORTE, or
  • manually triggered events directly in 4diac IDE
• It allows an easy step by step reproduction of an application
• The application can be monitored and every step of the reproduction can be fully observed
• Create parallel timelines of reproduction by triggering events from existing states
• Delete events and timelines when not needed anymore for the analysis
• Compare complete states of the application at different stages of the reproduction

Bug Fixes

• Fixed imports for constants in arrays when creating connections over UntypedSubApps
• Fixed importing of VarConfigParameter of TypedSubApps
• Fixed showing Pin-Tooltips to correctly show type/instance information
• Removed VarConfig column from output tables
