TIA MAC Module Builder

Scope

Use this skill for source-level development and review of Siemens Modular Application Creator modules built with Module Builder. It covers the framework above raw TIA Portal Openness: module lifecycle orchestration, model/use-case code, generated resource wrappers, UI/help resources, package construction, and qualification evidence.

The audited baseline is MAC V21.0.5 for TIA Portal V21 on .NET Framework 4.8. Treat those versions as a known-compatible baseline, not as a claim that they are the newest available versions.

Do not use this skill as authority for unrelated raw Openness automation. When a task crosses into direct Siemens.Engineering object access, load tia-csharp-common and the relevant domain skill selected by tia-openness-roadmap alongside this skill.
