Eplan Edz Files < 2025 >

There are two primary methods to import an EDZ file into your EPLAN environment (EPLAN Electric P8, EPLAN Pro Panel, or EPLAN Harness proD).

You may need to send your custom-designed macros to a colleague, a subcontractor, or back to a manufacturer for validation. Exporting an EDZ file ensures they receive the macro, the part number, and the symbols all at once.

Python script snippet to validate EDZ without EPLAN GUI: eplan edz files

import zipfile, xml.etree.ElementTree as ET
def validate_edz(edz_path):
with zipfile.ZipFile(edz_path, 'r') as zf:
# Check manifest
if 'META-INF/manifest.xml' not in zf.namelist():
return False, "Missing manifest"
# Parse part XML
part_files = [f for f in zf.namelist() if f.startswith('Parts/') and f.endswith('.xml')]
if not part_files:
return False, "No part data found"
# Basic reference check
for pf in part_files:
data = zf.read(pf)
if b'<macro_ref>' in data and b'</macro_ref>' in data:
# Further check would verify referenced macro exists in /Macro
pass
return True, "Basic validation passed"

It sounds like you’re asking about EPLAN EDZ files — likely wanting an explanation of what they are, how to use them, or possibly troubleshooting.

Here’s a concise breakdown:

Cause: The manufacturer defined a different mounting orientation (e.g., vertical mount vs. horizontal mount).

Solution:

If your company subscribes to the EPLAN Data Portal, you rarely need to manually handle EDZ files. You simply drag components from the portal directly into your project. However, when offline, or using a custom proprietary component, EDZ files are essential.
