Eplan Edz Files 2021 [2025]

Here’s a concise write‑up on EPLAN EDZ files in the context of the 2021 version.

Best Practices for 2021 Users

1. Use the EPLAN Data Portal first. Instead of hunting for EDZ files on a supplier's website, press Ctrl + D in 2021 to open the Data Portal. It streams the EDZ data directly into your project without file management headaches.
2. Keep a "Master Library." Do not import every EDZ file into your active project. Create a separate Master_2021_Parts.edb file and import there. Then, copy specific parts into your project.
3. Validate before the build. After importing a large EDZ file (e.g., a full Siemens catalog), run Check for inconsistencies in Parts Management. EPLAN 2021 is sensitive to orphaned data entries.

Guide: Working with EPLAN .edz Files (2021)

This guide explains what EPLAN .edz files are, how to open them with EPLAN Electric P8 2021 (or compatible versions), how to import/export, extract contents, troubleshoot common problems, and best practices for sharing and archiving.

Prerequisites:

• EPLAN Electric P8 2021 (or 2022/2023/2024 – backwards compatible).
• Administrator rights on your workstation (for writing to the parts database).
• The .edz file saved locally (not on a network drive with write restrictions).

How to Use EDZ Files in EPLAN 2021

Import
Options > Settings > User > Management > Parts > Import or
Tools > Parts > Management > [Additional] > Import – select .edz file.

Export
Select parts or macro projects → Export → choose EDZ format. You can choose to include referenced documents (PDFs, data sheets) as well.

Transitioning from Older EDZ to 2021 Format

Do you have an EDZ library from EPLAN 2.7? In EPLAN 2021, you cannot directly import a 2.7 EDZ. You must perform a two-step upgrade: Here’s a concise write‑up on EPLAN EDZ files

1. First, import the EDZ into an intermediate version (EPLAN 2.9).
2. From 2.9, export it as a new EDZ.
3. Finally, import that new EDZ into EPLAN 2021.

This ensures that the XML schema conversions are handled correctly, preventing "Invalid property" errors.

The Specifics of "EPLAN EDZ Files 2021"

Why focus on the year 2021? While EPLAN releases new versions annually, the 2021 version introduced significant changes to the Data Portal and file handling. If you are using EPLAN 2021, you need to know that: Best Practices for 2021 Users

1. Version Compatibility: An EDZ file exported from EPLAN 2022 may not be fully backward compatible with EPLAN 2021. The 2021 version expects specific XML schemas inside the zip archive.
2. Unicode Support: EPLAN 2021 enhanced its UTF-8 support. EDZ files created in older versions (e.g., 2.7 or 2.8) might require re-saving in 2021 to handle special characters correctly.
3. Data Portal Integration: In 2021, the EPLAN Data Portal started moving toward a cloud-first approach, making local EDZ backup files more important than ever.

Why 2021 Matters

EPLAN 2021 introduced several changes relevant to EDZ handling:

• Enhanced Data Portal v2021 – Manufacturers like Siemens, Phoenix Contact, and Weidmüller updated their export routines.
• Improved 64-bit performance – Importing large EDZ files (over 500 MB of 3D data) became more stable.
• Stricter schema validation – EDZ files created with older EPLAN versions (pre-2018) may trigger schema errors in 2021.

Step 2: Launch the Import Assistant

In the Parts Management window, click the Additional functions dropdown (icon with a wrench and gear). Select Import.
