A "better" download is useless if corrupted. Use the SHA-256 checksum included in modern ACX headers:
certutil -hashfile drive_config.acx SHA256
# Compare with Siemens reference hash
Scenario: A packaging line with 12 SINAMICS G120 drives.
Old method: Downloading full ACX containers from each drive (9 MB each → 108 MB total, 45 minutes).
Optimized method: A "better" download is useless if corrupted
Result: Total time reduced from 45 minutes to 4.5 minutes (90% improvement). Scenario: A packaging line with 12 SINAMICS G120 drives
For advanced users, write a script that: Result: Total time reduced from 45 minutes to 4

Siemens is actively investing in Docker-compatible configuration containers for edge devices. The next generation of MC drives will support OCI (Open Container Initiative) images, enabling:
Early access to the SACX Model Configuration Datapackage Container 2.0 is available through Siemens’ Industrial Engineering Beta Program. It promises delta downloads (only changed parameters) and encryption at rest.
