Support

Thanks for using the TIA Openness API. Here's how to get help.

Before you open an issue

Check the Getting started guide and the MCP / client setup (docs/INSTALL.md) — most setup problems are covered there.
Run the built-in diagnostics:
- In the tray GUI: API tab → Check environment (verifies the Windows group, x64 process, TIA Portal V21 + PublicAPI).
- From an AI client: call tia_ping — reachable:false means IP/port/firewall/serve is down; activated:false means the license is missing/invalid on the host; both true means you're ready.
Check the CHANGELOG — your issue may already be fixed in a newer release.

Priority support (email, with response targets per tier) is included with a paid license and the contact is delivered with your Activation License.

What to include in a bug report

It helps us a lot if you include:

App version (the app-v* tag, shown in the GUI / installer).
TIA Portal version and the target CPU (e.g. S7-1200 1214C, firmware version).
What you did, what you expected, and what happened (with the exact error text / envelope).
Whether you were driving the API directly, via the MCP, or via the harness plugin.
Output of Check environment / tia_ping if relevant.

Security disclosures

If you believe you've found a security vulnerability, please report it privately — open a GitHub security advisory instead of a public issue, so it can be fixed before disclosure.

Scope

This repository tracks the app / API (the licensed product). For the open client layers:

tia MCP — issues at the MCP repository.
tia-harness plugin — issues at renanlido/tia-harness.
