TIA V21 Project Skill
First Rule
Treat this workspace as the source of truth. Read knowledge/PROJECT.md first, then follow its read order. Do not reuse device names, IPs, HMI connection names, tag mappings, or export folders from any other project unless rediscovered in the active TIA project.
Project Layout
knowledge/: project facts, error ledger, validation checklist, maturity roadmap, and playbooks.tools/: project-local probes, Add-Ins, Data2Unified helper, and interface practice scripts.exports/: generated exports and diagnostics. Do not promote customer/project exports into global skills.docs/: longer design notes.env/: optional local environment notes and dependency bootstrap.knowledge/repository-policy.md: GitHub upload boundary for source, skill, framework, and knowledge files.
Default Workflow
- Confirm the current working directory is the repository root.
- Read
knowledge/PROJECT.md.
- Use
tools/TiaV21Probe for active TIA inspection, targeted export, PLC compile checks, and SIMATIC SD document export.
- Use TIA Add-Ins only for short, repeated in-TIA actions. Keep risky or experimental actions in standalone Add-In packages.
- Prefer Siemens Data2Unified for supported WinCC-to-Unified modernization, then repair/verify with project-local tools.
- For PLC block export, separate SimaticML XML from SIMATIC SD document export.
- For simulation, use S7-PLCSIM V21 for basic PLC logic and PLCSIM Advanced for IP/network/HMI closed-loop work.
- Record every surprise in
knowledge/error-ledger.md, add a repeat check to knowledge/validation-checklist.md, and update knowledge/maturity-roadmap.md when capability changes.
- Before publishing to GitHub, follow
knowledge/repository-policy.md and keep generated exports, binaries, and Siemens installation media local.
Safety Notes
- Avoid rebuilding external Openness probes during active TIA work unless needed; rebuilt executables can retrigger Openness Firewall prompts.
- If TIA Openness returns
EngineeringObjectDisposedException, stop scripted actions and restart TIA before continuing.
- In Add-In callbacks, avoid file dialogs,
MessageBox, explorer.exe, and long or batch Openness calls until proven stable.
- Current
ExportPlcBlockXmlAddIn is intentionally single-block only; batch export belongs in external probe/process-isolated workflows.
