| Extension | Description | Common Scenario | | :--- | :--- | :--- | | | EPLAN Data Format (for macros & symbols) | Importing or exporting a single macro, symbol library, or part data. Used when sharing a specific device or function, not a whole project. | | .emd | EPLAN Macro (Drawing) | A saved drawing fragment (e.g., a motor circuit or PLC card) that can be re-used across multiple projects. | | .ems | EPLAN Macro (Window/Symbol) | Similar to .emd but specifically for window macros or symbol-based macros. | | .txt / .csv | Plain text / Comma Separated Values | Used for importing/exporting parts lists, terminal strip definitions, cable schedules, or device tags to/from Excel or ERP systems. | | .dxf / .dwg | AutoCAD Drawing Exchange | Exporting EPLAN schematics to AutoCAD for non-EPLAN users. Importing building floorplans or panel layouts from mechanical engineers. | | .pdf | Portable Document Format | Standard output for plot generation, client approval, or manufacturing instructions. | | .xml | Extensible Markup Language | Advanced data exchange with CAE systems, PLM (Product Lifecycle Management), or custom scripts. Also used for OPC (Open Platform Communications) data. | 3. Specialized Configuration & Library Extensions These files define the behavior, appearance, and parts database of EPLAN.
EPLAN is a market-leading software suite for Computer-Aided Engineering (CAE), specifically designed for electrical, automation, and fluid power engineering. Unlike generic CAD programs, EPLAN is built around a centralized database model. Consequently, many "files" you see are not standalone drawings but references within a project database. eplan file extension
| Extension | Description | | :--- | :--- | | | EPLAN Parts Database (legacy) | An older format for the central component database (resistors, contactors, wires). Modern versions use SQL databases. | | .epf | EPLAN User Settings / INI | Stores user interface configurations, keyboard shortcuts, and workspace settings. | | .f29 / .f30 | EPLAN Font Files | Contains the specific fonts used for title blocks, labels, and terminal numbering. | | .alk | EPLAN Article (Part) Archive | A compressed archive for transferring parts data between systems. | | .asc | ASCII Symbol File | Used for importing/exporting custom symbol definitions in a text-based format. | 4. Report & Evaluation Extensions After designing a project, EPLAN generates reports. These are often saved as separate files. | Extension | Description | Common Scenario |
