Frequently Asked Questions

TIA Openness Manager supports TIA Portal V15 through V21 on Windows 10/11 (64-bit). Project files with extensions .ap15 through .ap21 can be opened directly.

Yes, TIA Portal must be installed on the same computer — but it does not have to be running. TIA Openness Manager can either open projects directly from file or attach to a running TIA Portal instance.

This is a Siemens requirement. Without membership in this Windows user group, TIA Portal refuses any Openness connection. Setup takes two minutes — see the Installation page for instructions.

Minimum 4 GB RAM, 8 GB recommended. For projects with many blocks we recommend 16 GB. Disk space required is about 500 MB for the application itself.

Basic is permanently free and includes the core features: import/export of individual blocks, compare, editor, hardware, HMI, OPC UA, and library. Limits: 1 file per operation, 50 blocks.

Pro (CHF 9.99/month or 99.99/year) unlocks safety blocks, protection profiles, AI Chat & MCP Tools, and Find Unused Blocks — with 1,000 files and 2,000 blocks per operation. Pro+ (CHF 29.99/month or 299.99/year) removes all limits and adds the Password Vault plus dedicated support.

Yes, on first launch you get a 30-day trial with all features unlocked. After the trial you can either continue with Basic (free) or subscribe.

Yes. The license is bound to your account and to your hardware — you can release the hardware binding yourself through the web portal and re-bind on a new machine. Up to 3 hardware switches per rolling 30 days are self-service. For more frequent switches, contact support@tiaopenessmanager.ch.

Up to 3 hardware switches per rolling 30 days — e.g. new laptop, hardware failure, or a second engineering workstation. For more frequent switches, contact support@tiaopenessmanager.ch.

The Org-Owner buys N seats via Stripe Checkout and assigns them to team members by email invite. Each user creates their own account; hardware binding happens at first login. Seats are per-seat named-user, not floating. Org-Owners manage seats, members, and billing through /profile/org in the web portal.

Through the Stripe Customer Portal — directly in the web portal under "Manage Subscription". Tier changes are pro-rated and effective immediately, without data loss and without contacting support.

Paid features remain available until the end of the billed period. After that the app automatically continues in the free Basic mode — your data and settings stay intact.

Payments are handled by Stripe: credit cards (Visa, Mastercard, Amex), Apple Pay, Google Pay, Amazon Pay, WeChat Pay, Klarna, Bancontact, and EPS. Billing is in CHF.

No. TIA Openness Manager works entirely locally on your machine. Project data never leaves your computer — only license validation communicates with our server. Details on the Security page.

The Password Vault encrypts all entries with AES-256-GCM. Your master password never leaves your machine and is never stored. If you lose your master password we cannot recover entries.

AI Chat uses external AI providers and requires an internet connection. You bring your own API key (e.g. Anthropic or OpenAI) — we do not proxy requests through our server.

TIA Openness Manager uses the official Siemens TIA Portal Openness API, but is not a Siemens product and is not certified by Siemens. It is developed and maintained independently.
