S100D Data Module Code Generator for UAV Systems 🚀 Overview This project is a specialized VBA-powered Excel tool developed for UAV (Unmanned Aerial Vehicle) System Engineers. It automates the generation of S100D compliant Data Module Codes (DMC) through an intuitive, selection-based interface.
By utilizing dynamic dropdowns and automated logic, the tool eliminates manual entry errors and ensures that technical documentation aligns perfectly with international aerospace standards (ASD S100D).

✨ Key Features Dropdown-Driven Logic: Generate complex codes by simply selecting system parameters from pre-defined menus.
UAV SNS Mapping: Integrated with Standard Numbering System (SNS) structures specific to Unmanned Aerial Systems.
One-Click Generation: A dedicated VBA engine that processes selections and outputs standardized strings instantly.
Data Export Functionality: Seamlessly transfer generated codes to master lists or external databases with the built-in export button.
Zero-Footprint Deployment: No installation required—runs entirely within Microsoft Excel, the primary workspace for most systems engineers.
📋 How It Works The tool is designed with a "Single Source of Truth" approach. Users follow a guided workflow on the main dashboard:
Selection Phase:
Category (Kategori): Select the high-level domain (e.g., Ground Systems).
System (Sistem Adı): Choose the major functional system (e.g., Equipment/Furnishings).
Sub-system (Altsistem Adı): Define the secondary technical layer.
Sub-category (Alt Kategori): Drill down to the specific assembly or component level.
Code Generation: * Click the "Kod Üretmek İçin Tıklayınız" (Click to Generate Code) button.
The macro concatenates the relevant indices to create the final S100D code (e.g., 125.31.001).
Export:
Click the "Output Verilerini Aktarmak İçin Tıklayınız" (Click to Export Output Data) button to save or transfer the result for use in Technical Publications (IETM/IETP).
🛠 Technical Specifications Language: VBA (Visual Basic for Applications)
Environment: Microsoft Excel (Macro-Enabled .xlsm)
Standard: ASD S100D Compliance
💡 Motivation "System engineering is about precision. Manual coding of S100D modules is a relic of the past. This tool was created to let engineers focus on design while the macro handles the documentation compliance."
🚀 Getting Started Download the .xlsm file from the repository.
