Locates the HMI DLL in `C:\ProgramData\Schneider Electric\Libraries\{Lib}-{Ver}\HMI\` 2. Decompiles using ILSpy CLI (ilspycmd) 3. Finds symbol\/faceplate classes in `{Lib}.Symbols.{Block}\/` and `{Lib}.Faceplates.{Block}\/` directories 4. Splits decompiled classes into EAE format: `.cnv.cs` (main) + `.cnv.Designer.cs` (InitializeComponent) 5. Updates namespaces according to the rules below 6. Creates `.cnv.resx` and `.cnv.xml` files **HMI Files to copy (per symbol\/faceplate):** ``` {Block}.def.cs - Faceplate accessor definitions {Block}.event.cs - Event argument classes {Block}.Design.resx - Design resources {Block}_fpDefault.cnv.cs - Faceplate implementation {Block}_fpDefault.cnv.Designer.cs - Designer-generated code {Block}_fpDefault.cnv.resx - Faceplate resources {Block}_fpParameter.cnv.cs - Parameter faceplate {Block}_fpParameter.cnv.Designer.cs {Block}_fpParameter.cnv.resx {Block}_fpTrend.cnv.cs - Trend faceplate {Block}_fpTrend.cnv.Designer.cs {Block}_fpTrend.cnv.resx {Block}_sDefault.cnv.cs - Default symbol {Block}_sDefault.cnv.Designer.cs {Block}_sDefault.cnv.resx {Block}_sDefault.cnv.xml - Symbol XML (ONLY for symbols) {Block}_sVertical.cnv.cs - Vertical symbol {Block}_sVertical.cnv.Designer.cs {Block}_sVertical.cnv.resx {Block}_sVertical.cnv.xml {Block}_sDisplayPv.cnv.cs - Display PV symbol {Block}_sDisplayPv.cnv.Designer.cs {Block}_sDisplayPv.cnv.resx {Block}_sDisplayPv.cnv.xml {Block}_sInstanceName.cnv.cs - Instance name symbol {Block}_sInstanceName.cnv.Designer.cs {Block}_sInstanceName.cnv.resx {Block}_sInstanceName.cnv.xml ``` **Important:** Faceplates (fp*) do NOT have .cnv.xml files. Symbols (s*) DO have .cnv.xml files. ### Step 3: Update Namespace & GUID in .fbt Files ```xml ``` **Sub-block namespace rules:** | Block Type | Action | |------------|--------| | Forked blocks (in hierarchy) | Update to target namespace | | Original library blocks | KEEP original namespace | | Adapter interfaces | KEEP original namespace | | DataTypes | KEEP original namespace | ```xml ``` ### Step 4: Update .cfg File The .cfg file links the CAT block to its HMI symbols. Update all paths: ```xml ..\HMI\AnalogInputBase\AnalogInputBase_fpDefault.cnv.Designer.cs<\/DependentFiles> ..\HMI\AnalogInputBase\AnalogInputBase_fpDefault.cnv.resx<\/DependentFiles> <\/Symbol> ..\HMI\AnalogInputBase\AnalogInputBase_sDefault.cnv.Designer.cs<\/DependentFiles> ..\HMI\AnalogInputBase\AnalogInputBase_sDefault.cnv.resx<\/DependentFiles> ..\HMI\AnalogInputBase\AnalogInputBase_sDefault.cnv.xml<\/DependentFiles> <\/Symbol> <\/HMIInterface> Value="AnalogInputBase\AnalogInputBase_CAT.offline.xml" \/> <\/CAT> ``` ### Step 5: Update HMI Namespaces (CRITICAL - Complex Rules) HMI files contain multiple categories of namespace references that require **different handling**: #### Namespace Reference Categories | Category | Pattern | Action | Example | |----------|---------|--------|---------| | **Block-specific (this block)** | `{Lib}.Symbols.{Block}`, `{Lib}.Faceplates.{Block}` | **UPDATE** to target | `SE.App2CommonProcess.Symbols.AnalogInputBase` → `SE.ScadapackWWW.Symbols.AnalogInputBase` | | **Cross-block (forked block)** | `{Lib}.Symbols.{OtherForkedBlock}` | **UPDATE** if in forked set | When forking hierarchy, update AnalogInputBase refs in AnalogInput | | **Cross-block (not forked)** | `{Lib}.Symbols.{NonForkedBlock}` | **KEEP** original | Keep `SE.App2CommonProcess.Symbols.Motor` if Motor not forked | | **SupportClasses** | `{Lib}.SupportClasses` | **ALWAYS KEEP** | `SE.App2CommonProcess.SupportClasses` - contains shared utilities | | **Base library** | `SE.App2Base.*` | **ALWAYS KEEP** | `SE.App2Base.Faceplates`, `SE.App2Base.Symbols`, etc. | | **Framework** | `System.*`, `NxtControl.*` | **ALWAYS KEEP** | Framework namespaces never change | #### Example: Using Directives in sDefault.cs ```csharp \/\/ From AnalogInputBase\/sDefault.cs (decompiled) \/\/ KEEP - Framework namespaces using System; using NxtControl.GuiFramework; \/\/ KEEP - Base library (SE.App2Base) using SE.App2Base.Faceplates; using SE.App2Base.Graphics; using SE.App2Base.SupportClasses; using SE.App2Base.Symbols; \/\/ UPDATE - Block-specific (this block is being forked) using SE.App2CommonProcess.Faceplates.AnalogInputBase; \/\/ → SE.ScadapackWWW.Faceplates.AnalogInputBase \/\/ KEEP - SupportClasses (shared utilities, NOT block-specific) using SE.App2CommonProcess.SupportClasses; \/\/ Contains: AnalogInputUnit, MotorAppearance, ValveAppearance, etc. namespace SE.App2CommonProcess.Symbols.AnalogInputBase; \/\/ → namespace SE.ScadapackWWW.Symbols.AnalogInputBase; ``` #### Cross-Block References (Hierarchy Forks) When forking a hierarchy (e.g., AnalogInput → AnalogInputBaseExt → AnalogInputBase), child blocks embed parent symbols: ```csharp \/\/ From AnalogInput\/sDefault.cs (decompiled) \/\/ UPDATE - Cross-block reference (AnalogInputBase IS in the forked set) using SE.App2CommonProcess.Symbols.AnalogInputBase; \/\/ → SE.ScadapackWWW.Symbols.AnalogInputBase \/\/ Fully qualified type in field declaration private SE.App2CommonProcess.Symbols.AnalogInputBase.sDefault analogFunction; \/\/ → SE.ScadapackWWW.Symbols.AnalogInputBase.sDefault \/\/ Instantiation analogFunction = new SE.App2CommonProcess.Symbols.AnalogInputBase.sDefault(); \/\/ → new SE.ScadapackWWW.Symbols.AnalogInputBase.sDefault(); ``` #### SupportClasses - Why They Must Be Preserved The `SupportClasses` namespace contains **library-wide utility classes** shared across all blocks: ``` SE.App2CommonProcess.SupportClasses\/ ├── AnalogInputUnit.cs # Used by AnalogInput symbols ├── AnalogOutputUnit.cs # Used by AnalogOutput symbols ├── MotorAppearance.cs # Used by Motor symbols ├── ValveAppearance.cs # Used by Valve symbols ├── PIDUnit.cs # Used by PID symbols ├── BitExtensions.cs # Utility methods ├── DynamicPropertyGrid.cs # UI helpers └── ... (60+ shared classes) ``` These classes are **NOT part of any specific block** and should **NEVER** have their references updated. **Files requiring namespace update:** - `{Block}.def.cs` - Multiple namespaces (Faceplates and Symbols) - `{Block}.event.cs` - Multiple namespaces - `{Block}_*.cnv.cs` - Single namespace per file (plus cross-block references) --- ## What eae-fork Does vs What eae-cat Does ### eae-fork (File Transformation) | Task | Description | |------|-------------| | Copy IEC61499 files | .fbt, .cfg, .offline.xml, .opcua.xml | | Copy HMI files | .def.cs, .event.cs, .cnv.*, .Design.resx | | Update namespaces | In .fbt and .cs files | | Generate new GUIDs | For all forked .fbt files | | Update .cfg paths | SymbolDefFile, SymbolEventFile, etc. | ### eae-cat (Project Registration) | Task | Description | |------|-------------| | dfbproj registration | 3 ItemGroups (None, Compile, Content) | | csproj registration | Compile, None, EmbeddedResource items | | Folders.xml update | CAT folder entries | | Validation | Verify block appears in library browser | **Why this separation?** - eae-fork handles file content transformation (namespace, GUID) - eae-cat handles project structure (registration, dependencies) - Each skill has clear, testable responsibilities --- ## Commands | Command | Description | |---------|-------------| | `\/eae-fork {Block} from {Lib} to {Target}` | Fork a block (asks about depth) | | `\/eae-fork --list {Lib}` | List blocks in source library | | `\/eae-fork --hierarchy {Block}` | Fork block with Base\/BaseExt chain | | `\/eae-fork --with-deps {Block}` | Fork block with all dependencies | | `\/eae-fork --dry-run` | Show what would be forked | --- ## Scripts ### Detect Block Type (Orchestration) The `detect_block_type.py` script examines source library files to determine block type for orchestration. ```bash # Basic usage python scripts\/detect_block_type.py # Examples python scripts\/detect_block_type.py AnalogInput SE.App2CommonProcess # Output: Detected CAT block, sub-skill: eae-cat python scripts\/detect_block_type.py MyLogicFB SE.App2Base # Output: Detected BASIC block, sub-skill: eae-basic-fb # JSON output for automation python scripts\/detect_block_type.py AnalogInput SE.App2CommonProcess --json # Verbose output with evidence python scripts\/detect_block_type.py AnalogInput SE.App2CommonProcess --verbose ``` **Detection Logic:** | Block Type | Detection Criteria | |------------|-------------------| | **CAT** | Has `.cfg` file with `` elements | | **Composite** | `.fbt` with `Format="2.0"` and ``, no `` | | **Basic** | `.fbt` with `` element | | **Adapter** | Has `.adp` file | | **DataType** | Has `.dt` file | **Exit Codes:** | Code | Meaning | |------|---------| | 0 | Success -

**Source files** for IEC61499 blocks (`.fbt`, `.cfg`, etc.) in `Files\/` directory - **Compiled DLLs** for HMI components in `HMI\/` directory - **No source files** for HMI symbols and faceplates This means to fork a block with full HMI functionality, we must decompile the HMI DLL. ### Decompilation Architecture ``` ┌─────────────────────────────────────────────────────────────────────┐ │ Library: C:\ProgramData\Schneider Electric\Libraries\ │ │ SE.App2CommonProcess-25.0.1.5\ │ ├─────────────────────────────────────────────────────────────────────┤ │ Files\/AnalogInputBase\/ │ HMI\/SE.App2CommonProcess.HMI.dll │ │ ├── AnalogInputBase.fbt │ (COMPILED -

**PERFORMANCE**: ~15 seconds for hierarchy (vs 3+ minutes manual editing in v6.0) - **RELIABILITY**: 100% systematic updates (no missed references) - **BENEFITS**: - ✅ Zero manual file editing required - ✅ Automatic cross-block reference updates (IEC61499) - ✅ Automatic HMI cross-reference updates (Designer.cs) - ✅ Clear progress reporting and summary - ✅ Maintains all v6.0 benefits (perfect HMI files, simple workflow) ### v6.0.0 - **PARADIGM SHIFT**: Hybrid manual\/automated workflow - Manual fork in EAE GUI → perfect HMI files (generated by EAE's designer) - Automated finalization → namespace updates + GUID generation + registration - **REMOVED**: Decompilation complexity - Deleted `decompile_hmi.py` (no longer needed) - Deleted `generate_hmi_from_reflection.py` (experimental, didn't work) - Removed ILSpy CLI dependency - Removed pythonnet dependency - **NEW**: `finalize_manual_fork.py` script - Validates manual fork completed in GUI - Updates namespaces in .fbt and .cs files - Generates new GUIDs - Registers block in dfbproj\/csproj - ~140 lines vs 500+ lines of decompilation code - **IMPROVED**: Reliability - ✅ 100% success rate (EAE-generated HMI files) - ✅ Simple & maintainable (namespace updates only) - ✅ Fast (~30 seconds per block) - ✅ User control (full visibility in GUI) - **BREAKING CHANGE**: Workflow now requires manual fork in EAE GUI first - Benefit: Perfect HMI files guaranteed - Trade-off: User must perform fork in GUI (30 seconds) - Net result: Simpler, more reliable overall workflow ### v5.1.0 - **CRITICAL FIX**: Complete HMI file generation (SUPERSEDED by v6.0) - Modified `fork_block.py::extract_decompiled_hmi()` to call standalone `decompile_hmi.py` as subprocess - Now creates ALL required HMI files: .cnv.cs, .cnv.Designer.cs, .cnv.resx, .cnv.xml, .Design.resx - Eliminated code duplication between fork_block.py and decompile_hmi.py - Fixed EAE GUI errors "Unable to load Designer.cs\/resx" files - **CRITICAL FIX**: Conditional aspmap.xml registration - Modified `register_dfbproj.py` to check if aspmap.xml exists before adding to dfbproj - Only SE.App2CommonProcess blocks have aspmap.xml, SE.App2Base blocks don't - Eliminated "Solution Integrity" warnings for missing aspmap.xml files - **IMPROVED**: Files now match manual fork structure exactly - **TESTED**: All symbols and faceplates open correctly in EAE GUI without errors - **NOTE**: This version attempted to solve HMI generation via decompilation - v6.0 takes simpler approach ### v5.0.0 - **MAJOR**: Automatic orchestration workflow - eae-fork now detects block type and automatically calls appropriate registration sub-skill - Users no longer need to manually run registration skills after forking - Added `detect_block_type.py` script for block type detection - **NEW**: Block type detection examines source files to determine: - CAT (has .cfg with HMIInterface) - Composite (FBNetwork, no BasicFB) - Basic (has BasicFB) - Adapter (has .adp file) - DataType (has .dt file) - **NEW**: Orchestration routing to sub-skills: - CAT → `\/eae-cat --register-only` - Composite → `\/eae-composite-fb --register-only` - Basic → `\/eae-basic-fb --register-only` - Adapter → `\/eae-adapter --register-only` - DataType → `\/eae-datatype --register-only` - **IMPROVED**: Complete workflow in single command ### v4.0.0 - **MAJOR**: Full HMI decompilation workflow - Added `decompile_hmi.py` script for extracting HMI from compiled DLLs - Uses ILSpy CLI (ilspycmd) for decompilation - Splits decompiled classes into EAE format (.cnv.cs + .cnv.Designer.cs) - Preserves full visual implementation (not stubs) - **NEW**: Decompilation process: 1. Locate HMI DLL in library folder 2. Decompile using ILSpy to temp directory 3. Find symbol\/faceplate classes for the target block 4. Extract InitializeComponent to Designer file 5. Update namespaces with proper categorization rules 6. Generate .resx and .cnv.xml files - **IMPROVED**: Cross-block reference handling for hierarchy forks - `--forked-blocks` flag to specify all blocks being forked - Updates cross-references only for blocks in forked set - **REQUIREMENT**: ILSpy CLI (`dotnet tool install -g ilspycmd`) ### v3.1.0 - **CRITICAL FIX**: Smart HMI namespace handling with proper reference categorization - Block-specific namespaces (Symbols\/Faceplates.{Block}): UPDATE if block is forked - Cross-block references: UPDATE only if referenced block is in forked set - SupportClasses: ALWAYS PRESERVE (library-wide shared utilities) - Base library (SE.App2Base.*): ALWAYS PRESERVE - Framework (System.*, NxtControl.*): ALWAYS PRESERVE - **ENHANCED**: Cross-block reference handling for hierarchy forks - When forking AnalogInput hierarchy, AnalogInput's reference to AnalogInputBase.sDefault is properly updated - Fully qualified type references and instantiations are updated - **DOCUMENTED**: Comprehensive namespace reference categories with examples - **IMPROVED**: Better logging of preserved library references ### v3.0.0 - **CRITICAL FIX**: HMI files must be COPIED from source, not generated - Insight from manual fork analysis in EAE GUI - HMI files contain complete implementations with designer code - **EXPANDED**: eae-fork now handles Steps 1-5: - Step 1: Copy IEC61499 files - Step 2: Copy HMI files (NEW - from source library) - Step 3: Update namespaces in .fbt files - Step 4: Update .cfg file (expanded: all path attributes) - Step 5: Update HMI namespaces in .cs files - **DOCUMENTED**: Complete file list from manual fork analysis - IEC61499 files: 8 file types - HMI files: Up to 28 files per block (varies by symbols\/faceplates) - **DOCUMENTED**: Detailed .cfg file structure with all required attributes - **CLARIFIED**: eae-cat handles project registration only (dfbproj, csproj, Folders.xml) ### v2.1.0 - Clear separation of concerns between eae-fork and eae-cat - Removed dfbproj registration from eae-fork (delegated to eae-cat) ### v2.0.0 - Added fork depth user interaction question - Added dfbproj registration (now moved to eae-cat) - Added HMI file generation (now moved to eae-cat) ### v1.0.0 - Initial release - Basic file copy and namespace update
