📋 Detailed Installation Guide

Prerequisites - READ THIS FIRST! ⚠️

🚨 CRITICAL REQUIREMENT: Python 3.12 ONLY

  • This project REQUIRES Python 3.12 - earlier versions will fail
  • Studio 5000 SDK is incompatible with Python 3.11 and earlier
  • Verify your Python version FIRST before proceeding

System Requirements:

  • Python 3.12.x (Download from python.org)
  • Studio 5000 Logix Designer v36 or later installed
  • Windows Operating System (Studio 5000 SDK is Windows-only)
  • Administrator privileges may be required for initial setup

Step-by-Step Setup

Step 1: Install Python 3.12
  1. Download: Go to python.org and download Python 3.12
  2. Install: During installation, CHECK "Add Python to PATH" ✅
  3. Verify: Open Command Prompt and run: 
    python --version
# Must show: Python 3.12.x (if not, restart command prompt)
Step 2: Get the Project
  1. Clone the repository: 
    git clone <repository-url>
cd Studio5000_MCP_Server
Step 3: Install Dependencies (CRITICAL!)

  1. Install all required packages:

    pip install -r requirements.txt

    This installs:

    • Core Components: BeautifulSoup, XML processing, async support
    • AI & Vector Search: PyTorch, sentence-transformers, FAISS vector database
    • Semantic Analysis: Vector embeddings for instruction and L5X search
    • Performance: Optimized versions for production use

    If you get errors, try:

    python -m pip install --upgrade pip
pip install -r requirements.txt

    Note: Vector database components (torch, sentence-transformers, faiss-cpu) are included for semantic search capabilities. These enable advanced L5X analysis and instruction search features.

Step 3.5: Install Studio 5000 SDK (CRITICAL for .ACD files!) 🚨

⚠️ TEAMMATES MUST DO THIS STEP - Skip only if you don't need .ACD file creation

  1. Find the SDK wheel file in your Studio 5000 installation:

    # Look for this file (version may vary):
dir "C:\Users\Public\Documents\Studio 5000\Logix Designer SDK\python\logix_designer_sdk-*-py3-none-any.whl"

  2. Install the SDK wheel file:

    # Replace with your actual file path and version:
pip install "C:\Users\Public\Documents\Studio 5000\Logix Designer SDK\python\logix_designer_sdk-2.0.1-py3-none-any.whl"

  3. Alternative - if you can't find the wheel file:

    # Navigate to the SDK directory and install from there:
cd "C:\Users\Public\Documents\Studio 5000\Logix Designer SDK\python"
pip install logix_designer_sdk-*-py3-none-any.whl

Without this step: Documentation and L5X generation will work, but .ACD file creation will fail!

Step 4: Test Your Installation ✅

  1. Run the test command:

    python src/mcp_server/studio5000_mcp_server.py --test

  2. You should see:

    • ✅ "Documentation indexed successfully" (500+ instructions found)
    • ✅ "SDK Available: True" (if you installed the SDK wheel file correctly)
    • ✅ "SDK Available: False" (OK if you skipped SDK installation - L5X generation still works)
    • ✅ Sample search results and code generation tests

  3. If SDK Available shows False but you installed the wheel file:

    • Check the wheel file path was correct
    • Try: python -c "import logix_designer_sdk; print('SDK OK')"

  4. If tests fail completely, check the Troubleshooting section

🎯 Three Powerful Approaches for PLC Project Creation

Your MCP server supports THREE different approaches for PLC project creation, each optimized for different use cases:

🥇 Approach 1: L5X Generation + Manual Import (WITH LIMITATIONS)

🎯 Generates: L5X project structure with MainProgram and MainTask
⚠️ Output: L5X file that may need manual RLL formatting fixes
🎯 Best for: Project templates and basic structure creation
🎯 Manual Steps:

  1. Generate L5X template (30 seconds)
  2. Fix RLL formatting issues in text editor
  3. Import corrected L5X into Studio 5000

Usage: "Create an L5X project template for conveyor control"
Tool: create_l5x_project

⚡ Reality Check:

  • ⚠️ Generated L5X may have XML formatting issues
  • ✅ Good for project structure templates
  • ✅ Import only the corrected logic you need
  • ✅ Professional workflow once files are validated

🥈 Approach 2: Empty .ACD Templates (RELIABLE)

✅ Generates: Empty .ACD project file (clean template)
✅ Output: Blank project that opens directly in Studio 5000
✅ Best for: Starting point for completely manual development
🛠️ Manual Steps: Create MainProgram and MainTask yourself, develop logic manually

Usage: "Create an empty .ACD template for manual development"
Tool: create_acd_project

Why This Works:

  • ✅ 100% reliable empty project creation
  • ✅ No complex SDK operations that can fail
  • ✅ Clean foundation for manual development

🥉 Approach 3: AI Logic Generation Only (For Existing Projects)

🧠 Generates: Professional ladder logic with validation
🧠 Output: Copy-paste ready ladder logic code
🧠 Best for: Adding logic to existing company projects
🧠 Manual Steps: Copy generated logic into your existing routines

Usage: "Generate conveyor control logic for my existing project"
Tool: generate_ladder_logic

🎯 Current Status & Recommended Workflow

What Actually Works: ✅ AI Logic Generation + Empty ACD Templates + Manual Development

Realistic Industrial Workflow:

  1. Generate AI Logic: "Create conveyor control with jam detection" → Professional ladder logic code
  2. Create Empty ACD: Clean project template ready for development
  3. Manual Development: Copy logic into Studio 5000, create MainProgram/MainTask manually
  4. Production Ready: Fully functional logic developed using AI as assistance

Why This is Honest and Practical:

  • ✅ 100% reliable empty ACD creation - No complex failures
  • ✅ AI-generated logic works - Good foundation for manual development
  • ✅ Professional workflow - AI assists, human engineer validates and implements
  • ✅ Zero import issues - No broken XML or SDK complications

Reality Check on Advanced Features:

  • ⚠️ L5X Generation: Creates structure but may need XML fixes before import
  • ⚠️ Complete ACD Projects: Experimental SDK features that often fail
  • ✅ Fast Validation: 100% reliable for catching logic errors
  • ✅ Vector Search: Works great for analyzing existing projects

Troubleshooting

❗ Critical Issues

1. Python Version Mismatch

Problem: MCP server starts but SDK features don't work or you get import errors.

Solution:

# Check your Python version
python --version
# Must show 3.12.x

# If not 3.12, install Python 3.12 and use full path in Claude config:
"command": "C:\\Users\\YourUsername\\AppData\\Local\\Programs\\Python\\Python312\\python.exe"

Why: Studio 5000 SDK requires Python 3.12 specifically. Earlier versions will cause SDK import failures.

2. Documentation Path Not Found

Problem: "Main index file not found" or "No instructions found"

Solution - Find Your Documentation Path:

  1. Open File Explorer and search for: 17691.htm
  2. Look in these common locations: 
    C:\Program Files (x86)\Rockwell Software\Studio 5000\Logix Designer\ENU\v36\Bin\Help\ENU\rs5000\17691.htm
C:\Program Files\Rockwell Software\Studio 5000\Logix Designer\ENU\v36\Bin\Help\ENU\rs5000\17691.htm
C:\Program Files (x86)\Rockwell Software\Studio 5000\Logix Designer\ENU\v37\Bin\Help\ENU\rs5000\17691.htm
  3. Set the correct path (everything except the filename): 
    # Via environment variable
set STUDIO5000_DOC_PATH=C:\Program Files (x86)\Rockwell Software\Studio 5000\Logix Designer\ENU\v36\Bin\Help\ENU\rs5000

# Or via command line
python src/mcp_server/studio5000_mcp_server.py --doc-root "C:\Program Files (x86)\Rockwell Software\Studio 5000\Logix Designer\ENU\v36\Bin\Help\ENU\rs5000" --test
3. SDK Not Available

Problem: "Studio 5000 SDK not available" or "SDK import failed"

Most Common Cause: You didn't install the SDK wheel file! ⚠️

Solution:

  1. 🚨 CRITICAL: Install the SDK wheel file first:

    # Find and install the wheel file (most teammates miss this step!)
pip install "C:\Users\Public\Documents\Studio 5000\Logix Designer SDK\python\logix_designer_sdk-*-py3-none-any.whl"

  2. Check SDK Installation:

    • Look for: C:\Users\Public\Documents\Studio 5000\Logix Designer SDK\python\
    • If missing, reinstall Studio 5000 with SDK components

  3. Verify SDK Works:

    # Test if SDK is now available
python -c "import logix_designer_sdk; print('SDK OK')"

  4. If still failing, set SDK Path:

    set STUDIO5000_SDK_PATH=C:\Users\Public\Documents\Studio 5000\Logix Designer SDK\python

⚠️ Common Setup Issues

4. Server Fails to Start

Symptoms: Server crashes immediately or shows JSON-RPC errors.

Solutions:

  • Check Python path in Claude config - use full path to Python 3.12
  • Verify working directory - "cwd" should point to project root
  • Check file permissions - ensure read access to all project files
  • Test in isolation: 
    python src/mcp_server/studio5000_mcp_server.py --test
5. Environment Variables Not Working

Problem: Server still uses hardcoded paths despite setting environment variables.

Solutions:

  1. Restart Command Prompt/IDE after setting environment variables
  2. Check variable names (case sensitive):
    • STUDIO5000_DOC_PATH
    • STUDIO5000_SDK_PATH
    • PYTHON312_PATH
  3. Test environment variables: 
    echo %STUDIO5000_DOC_PATH%
echo %STUDIO5000_SDK_PATH%
6. Claude Desktop Configuration Issues

Problem: MCP server not appearing in Claude Desktop.

Solutions:

  1. Check config.json syntax - use JSON validator
  2. Restart Claude Desktop completely after config changes
  3. Use absolute paths - no relative paths in Claude config
  4. Check Claude logs in %APPDATA%\Claude\logs\

  • ✅ L5X file analysis (tested with 49k+ line files)
  • ✅ SDK documentation search (comprehensive method database)
  • ✅ Pattern recognition (start/stop, timer, counter patterns)

⚠️ What's Partially Working (Needs Manual Fixes):

  • ⚠️ L5X project file generation (creates structure but RLL formatting issues)
  • ⚠️ Complete ACD creation (experimental SDK partial import features)
  • ⚠️ Smart code insertion (analysis works, insertion is SDK-dependent)

🔧 What Needs Development:

  • 🔧 Proper RLL XML generation (currently outputs raw text in CDATA)
  • 🔧 Reliable SDK partial import (complex and error-prone)
  • 🔧 End-to-end project automation (currently requires manual steps)

Future Enhancement Opportunities

High Priority (Completed! ✅):
  • ✅ Complete SDK Integration: COMPLETED! Full program/task creation now implemented
  • ✅ Routine Import/Export: COMPLETED! Using SDK's partial import functionality
  • ✅ Program Structure Creation: COMPLETED! Automatically creates MainProgram and MainTask
  • Tag Management: Implement SDK tag creation and management operations (TODO)
  • Advanced Project Operations: Build, upgrade, and deployment automation (TODO)
Medium Priority (Feature Expansion):
  • Additional Language Support: Structured Text (ST) and Function Block Diagram (FBD) generation
  • Enhanced Pattern Recognition: More complex industrial automation patterns
  • ✅ SDK Documentation Improvement: COMPLETED! Parser now finds 63 LogixProject methods + 39 examples = 102+ operations (was 22)
  • Advanced Validation: Static analysis and best practices checking
Lower Priority (Extended Integration):
  • Multiple Studio 5000 Versions: Dynamic version detection and compatibility
  • Integration Extensions: Support for FactoryTalk View, RSLinx, and other Rockwell tools
  • Cloud Deployment: Web-based interface for team collaboration
  • Caching System: Improved performance for large documentation sets
🎯 The Honest Value: AI-Assisted Development Workflow

The system provides valuable AI assistance for PLC development:

  • ✅ AI Logic Generation: Convert natural language to ladder logic text (WORKS WELL)
  • ✅ Empty ACD Templates: Clean project files ready for manual development (RELIABLE)
  • ⚠️ L5X Structure Creation: Creates project templates that may need formatting fixes (PARTIAL)
  • ✅ Fast Validation: Instant syntax and instruction checking (PRODUCTION READY)
  • ✅ Vector Search: Analyze existing projects semantically (PRODUCTION READY)

You CAN ask: "Generate conveyor control logic with jam detection" and get high-quality ladder logic code to use as a foundation for manual development. The AI assists, but human engineers still need to implement and validate the final solution.
