Scope
Project, portal, and project/global library lifecycle — full C# Openness implementation.
When the roadmap routes here, the entire solution is C#. Do not mix with Python wrapper calls. Always load tia-csharp-common first (done by roadmap).
Reference files
Load ONLY the reference file(s) relevant to the task. Do not load all files at once.
| Reference file | When to use |
|---|---|
references/project-lifecycle.md |
Load when the task involves project-level lifecycle operations: Open, OpenWithUpgrade, Create, Save, SaveAs, Close, Archive, Retrieve, RetrieveWithUpgrade, delete, or copy. |
references/library-operations.md |
Load when the task involves project/global libraries, library folders, master copies, library types or versions, type instances, release/default/discard, update/harmonize/cleanup, or library comparison. |
references/project-attributes.md |
Load when the task involves reading project metadata (Author, Name, Version, Path, Size, dates), project history entries, used products, simulation/virtual PLC properties, or accessing the VCI service entry point. |
references/language-settings.md |
Load when the task involves project languages, active/editing/reference languages, multilingual text (MultilingualText, MultilingualTextItem), CommentML on devices, or VCI language import options. |
references/umac-and-auth.md |
Load when the task involves UMAC-protected project operations, UmacDelegate, Authentication events, ProjectOpenMode (Primary/Secondary), or UMAC user types. |
references/compile.md |
Load when the task involves compiling any object (PlcSoftware, HmiTarget, Device, CodeBlock, etc.) via ICompilable or reading CompilerResult. |
references/portal-settings.md |
Load when the task involves TiaPortalSettingsFolder (UI language, search index), ObjectIdentifierProvider, SystemDiagnostics settings export/import, or read-only project access. |
references/vci-management.md |
Load when the task involves managing VCI workspaces, workspace groups, creating user groups, or connecting/exporting objects to a VCI workspace. |
references/vci-operations.md |
Load when the task involves VCI mapped objects, synchronizing changes between project and workspace, or performing object comparisons. |
For tasks spanning multiple areas, load all relevant reference files before generating code.
Execution pattern
- Create or attach to
TiaPortalinstance (seetia-csharp-common) - Open, create, or retrieve
Project - Use
ExclusiveAccess/Transactionwhere needed (seetia-csharp-common) - Perform project-level or library operations; require explicit authorization before any library/project mutation
- Save / archive / close at the correct synchronisation point
- Dispose the TIA Portal session
