Notes:

The engineering software V8.1 is available as an upgrade package for downloading from the Internet. Existing engineering software V8 + SP1 is required for installation of the upgrade package. Beside the upgrade, a hotfix for the engineering software V8 + SP1 (no upgrade) is available for downloading; see https://support.industry.siemens.com/cs/de/en/view/109480456.

The engineering software product package includes the associated block library service pack, if available. The service pack for the engineering software migration V7-V9 or engineering software V7 can only be obtained in the package with the engineering software. The service pack for these two versions is not available for downloading.
