While these files are internally ZIP archives and can be viewed with tools like 7-Zip or WinZip , users strongly recommend using the official Retrieve function within the Siemens TIA Portal to avoid file corruption.
It effectively compresses massive project data—including PLC code, HMI screens, and hardware configurations—into a manageable single file. This makes it significantly easier to share or archive complete automation systems without losing individual file links.
Moderate; requires specific software (TIA Portal) to fully utilize. Provide the device model or brand (e.g., Zadez mouse or Antminer Z15 Go to product viewer dialog for this item. ) to get more specific instructions. What is it? How to open a ZAP15 file? - FILExt
The "ZA15" (or .zap15) file is the industry standard for bundling complex industrial automation projects into a single, compressed package.
A common hurdle is version compatibility. Because the "15" in the extension signifies TIA Portal version 15, you generally need that specific version (or newer) to "Retrieve" and open the project. Opening a v15 file in v17, for instance, requires a conversion process that can sometimes be tedious.
For engineers, these archives are vital for maintaining "golden" backups of factory floor logic, ensuring that if a hardware failure occurs, the exact software state can be redeployed quickly. Summary Data Integrity ⭐⭐⭐⭐⭐ Excellent; rarely loses data when retrieved properly. Portability ⭐⭐⭐⭐ High; turns hundreds of files into one. Ease of Use
