Directory Guide

archives/

Compressed TIA Portal global library archives, grouped by library name.

Use these when you want the simplest import path in TIA Portal.

libraries/

Expanded TIA Portal global library folders, grouped by library name and version.

These folders intentionally include TIA internal folders such as System, TMP, Vci, XRef, IM, and AdditionalFiles. Do not delete or ignore these folders when you want the .al21 library to remain openable in TIA Portal.

blocks/xml/

TIA Openness XML exports of PLC blocks. These files are the best place to review behavior changes in GitHub.

blocks/udt/

PLC data type source files used by the libraries.

Usage

1. Download the required .zal21 file from archives/ or the GitHub Release page.
2. Open TIA Portal V21.
3. Open the global library or retrieve the archive.
4. Drag the required blocks or types into your PLC project.

Notes

• The libraries are intended for TIA Portal V21.
• FlowControl now includes base, v0.1.1, v0.1.2, and v0.1.3 exports.
• MotionControl now includes base and v0.1.1 exports.
• SingleSolCyl has archive, expanded library, and LAD/SCL XML block exports.
• Keep XML exports in Git for easier diff and review.
• Keep .zal21 archives for convenient reuse.
• Keep expanded .al21 library folders complete. Their internal folders are part of the TIA library structure.
