TIA Portal Starter Kit Licensing Resolving Version Mismatch

1. Overview: TIA Portal Starter Kit Version Drift

Engineers procuring Siemens S7-1200 starter kits frequently encounter a licensing and version-drift problem: two kits purchased months apart from the same authorized distributor can ship with different TIA Portal Step 7 Basic versions on the bundled USB media. One kit may carry V17 while a later purchase ships with V16, V18, V19, or V20. The hardware is identical, the catalog number is identical, but the included software is not.

Because Siemens does not bundle free upgrade rights with these kits, the buyer is left with a sealed, shrink-wrapped current product containing superseded engineering software. This article documents the root cause, the technical remediation path, and the official Siemens channels an engineer should follow to either upgrade, exchange, or work around the mismatch without losing project data or license entitlement.

2. TIA Portal Step 7 Basic Version Reference

Understanding the release cadence clarifies why a kit purchased in March may contain software that was current in the prior calendar year. Siemens follows a major-version release cycle for TIA Portal, each version bundled with a corresponding SIMATIC Automation Tool and CPU firmware support matrix.

Version compatibility rule: A TIA Portal version can open, monitor, and edit projects created in its own version or the two prior versions. Down-conversion is not supported. A V17 project cannot be opened in V16, but a V16 project can be opened (read-only or with promotion) in V18. This is the root reason why a starter kit stuck on V16 becomes a deployment liability when the rest of your engineering fleet is running V19 or V20.

3. Anatomy of a S7-1200 Starter Kit

A standard SIMATIC S7-1200 starter kit (article 6AV6651-7DA02-3AA4 family) typically contains the following components in a single sealed retail box:

1. SIMATIC S7-1200 CPU (commonly CPU 1214C DC/DC/DC or 1215C AC/DC/RLY depending on the regional SKU)
2. SIMATIC HMI panel (commonly KTP700 Basic or KTP400 Basic)
3. Digital and analog input/output simulator
4. Ethernet PROFINET cable (RJ45)
5. S7-1200 documentation set (printed or PDF)
6. USB media containing the TIA Portal Step 7 Basic installer plus a floating license tied to a License Key file
7. CoA (Certificate of License) for Siemens Automation License Manager

The USB media is the variable component. Siemens packages the box in production batches. Once a batch is sealed and palletized, the media inside does not get refreshed to a newer TIA Portal version, even if a new TIA version ships weeks later. Distributors receive inventory on a first-in / first-out basis, so a kit purchased today can legitimately contain software that was current before the most recent TIA release.

4. TIA Portal Licensing Models in Detail

Siemens offers several licensing models. The starter kit uses the Floating License model via the Siemens Automation Software License framework. Refer to the official TIA Portal V20 licensing documentation and the community-curated TIA Portal types of license reference for the full taxonomy.

For a starter kit, the buyer receives a Floating License with a perpetual License Key that authorizes the specific major version printed on the USB media. The license does not auto-upgrade when a new TIA Portal release ships. To run a newer version, you must either:

• Purchase an Upgrade License that maps the existing Key to a newer major version, or
• Subscribe to SUS (Software Update Service) and apply each released upgrade, or
• Install a separate, fully-licensed copy of the newer TIA Portal version (the cost of a new full license).

5. Automation License Manager (ALM): The Technical Core

The Siemens Automation License Manager is a Windows service that stores, transfers, and validates License Keys. Every interaction with a TIA Portal license passes through ALM. If you cannot start TIA Portal, cannot activate a Key, or cannot transfer a Key between machines, the fault is almost always in ALM, not in TIA Portal itself.

5.1 Verifying ALM Version Compatibility

ALM must be updated to a version compatible with the TIA Portal version you intend to run. Older ALM versions can detect newer License Keys but will refuse to validate them. The required ALM version is documented in the TIA Portal installation and licensing guide for each TIA release.

5.2 Verifying the License Key State

Open Automation License Manager from the Start menu, navigate to the machine where the License Key was installed, and expand the tree. The Key will appear in one of the following states:

• Valid (green check) - License is bound to a TIA version that matches the installed software. TIA Portal will start.
• Invalid version (yellow triangle) - License is bound to a TIA version newer than the installed TIA Portal software. TIA Portal will start in trial / read-only mode.
• Invalid signature (red cross) - License file corruption, hardware swap, or OS reinstall. License must be reactivated.
• Unknown (gray) - ALM cannot contact the License Server. Check network and firewall rules for TCP 4410 and UDP 4410.

For a starter kit on a sealed box, the License Key on the USB stick should validate immediately when copied to the target PC and registered in ALM, provided the TIA Portal version on the target PC matches the version printed on the License Key certificate.

6. Diagnosing the Version Mismatch Problem

When a second starter kit arrives carrying a different TIA Portal version than the first, the engineer faces a concrete set of symptoms:

6.1 Symptom Matrix

6.2 Confirming the Mismatch is in the Kit, not the Engineer

1. Insert the USB media and open setup.exe. Read the installer banner - it states the TIA Portal version.
2. Locate the Certificate of License (CoL) card in the box. The CoL has a printed License Key with a major-version suffix (e.g., XXXX-XXXX-XXXX-XXXX-V17).
3. Cross-check the installer version and the CoL version. If they differ, the kit is internally inconsistent (a manufacturing fault - escalate to Siemens support).
4. If both are V16 and the engineer's existing TIA Portal is V17, the engineer must either install V16 alongside V17, or upgrade the V16 Key to V17.

7. Resolution Path A: License Upgrade via Siemens

This is the supported route when you want to bring the older starter-kit license up to a newer TIA version without buying a full new license.

7.1 Upgrade License Order

1. Locate the existing License Key from the original Certificate of License.
2. Visit the Siemens Industry Mall and search for the upgrade article corresponding to your source version and target version. The article numbers follow the pattern 6AV2xxx-xAAxx-xAx.
3. Specify the existing License Key in the order notes - Siemens uses this to bind the upgrade to your key.
4. Receive a new CoL with an upgraded License Key.
5. In ALM, return the old Key and register the new Key on the target PC.

7.2 Cost and Time Expectations

Upgrade licenses are substantially cheaper than full licenses. A typical Step 7 Basic V16-to-V17 upgrade is roughly 30 to 40 percent of the cost of a full V17 license. Delivery is usually 2 to 5 business days for electronic License Keys, longer for physical CoL cards.

8. Resolution Path B: Software Update Service (SUS) Subscription

If the engineering shop is going to consume future TIA Portal versions on a rolling basis, the Software Update Service is the more economical long-term answer.

1. SUS is purchased per license, per year, and is renewable.
2. For the duration of an active SUS, every major and minor TIA Portal release for that license family is included.
3. When SUS lapses, the License Key reverts to the highest version covered by the last paid subscription. The user does not lose the ability to run that version, only the right to upgrade further.

For a single-laptop, single-engineer environment with a starter kit, SUS is overkill. For a multi-engineer firm with five or more TIA Portal seats, SUS consolidates upgrade cost and prevents the kind of version drift documented in this article.

9. Resolution Path C: Return and Exchange

Many authorized Siemens distributors will exchange a sealed-box starter kit for a current-version equivalent if the kit has not been opened. The specific distributor policy varies by region; for example, RS Components in Ireland and the UK has historically honored exchanges for sealed electronics kits.

1. Verify the box seal is intact. The shrink wrap and barcode label must be unbroken.
2. Contact the distributor's business-to-business desk (not the consumer returns desk) within the standard return window - typically 14 to 30 days from invoice date.
3. Provide the invoice number and a clear statement: "Sealed starter kit shipped with superseded software; requesting exchange for current-software equivalent."
4. If the distributor cannot source a current-version kit, request a full refund and purchase the desired TIA Portal version through a Siemens digital delivery channel.

Once the box is opened, the License Key is considered activated and the kit is non-returnable per standard software licensing terms. Engineers who anticipate this issue should leave the box sealed until the USB media is verified, then open only after confirming the version is acceptable.

10. Resolution Path D: Coexistence Install (V16 and V17 Side by Side)

If upgrade budget is constrained but the engineer needs to access an older project that was authored in V16, install V16 and the newer version side by side on the same PC. Siemens supports parallel installation of two major TIA Portal versions, with the following caveats:

• Each version must be installed under its own directory (the installer handles this automatically).
• Each version requires its own License Key.
• Project files created in V16 must be explicitly saved-as and promoted to V17 format if you intend to use them in V17 long-term.
• ALM can manage multiple Keys for the same user on the same host; the active Key is selected per-session.

This is the cheapest path if the older version is needed for maintenance of legacy S7-1200 firmware and the newer version is needed for new development.

11. Resolution Path E: Direct Procurement of Current-Version License

If the kit has already been opened and the V16 license has been activated, the most straightforward commercial path is to buy a fresh Step 7 Basic V20 (or current) license outright. This is more expensive than an upgrade, but it is the cleanest administrative option for record-keeping and asset management.

1. Search the Siemens Industry Mall for "Step 7 Basic V20" or the current release.
2. Select Floating License if you intend to use ALM-managed transfer; select Single License if the Key will live on one machine only.
3. Download the electronic delivery version for fastest turnaround (typical 1 to 24 hours).

12. Field-Proven Best Practices

1. Document the License Key on receipt. Photograph the Certificate of License on the day the kit arrives. Store the photo in a managed cloud drive with a date-stamped filename. If the CoL is lost, the photo is the only proof of ownership.
2. Verify the USB media version before opening the TIA Portal installer. Read the version on the USB sticker; do not start the installer until the version is confirmed acceptable.
3. Maintain a master engineering PC with the highest TIA version and a "compatibility PC" with the lowest version your installed base requires. This avoids the in-the-field scramble when a V16 project arrives for modification.
4. Subscribe to SUS for production engineering teams of three or more seats. For solo engineers, evaluate upgrade-vs-full-license on a per-release basis.
5. Apply TIA Portal Service Packs promptly within a major version. SP updates are free and address CPU firmware, security, and HMI runtime issues. They are not the same as major-version upgrades; SUS is not required for SPs.
6. Keep ALM updated independently of TIA Portal. ALM is shipped on the TIA Portal media but is also available as a standalone download. Updating ALM alone does not require an active TIA license.
7. Audit licenses annually. Open ALM, walk the tree, and reconcile against the asset register. Floating licenses can be orphaned by reinstalled operating systems.

13. Verification Checklist After Remediation

1. TIA Portal launches without a license warning dialog.
2. ALM reports the License Key as Valid (green check) for the installed TIA version.
3. A test project can be created, downloaded to a known-good S7-1200 CPU, and the CPU goes to RUN.
4. Online monitoring shows live tag values from the CPU.
5. If a project was promoted across versions, the promotion log shows no error and the project compiles without warnings.
6. If an upgrade License Key was applied, the old Key is returned in ALM to free the slot for the new Key on a second machine (if needed).

14. When to Escalate to Siemens Support

Escalate through official Siemens channels (SiePortal or the regional Siemens support hotline) when any of the following apply:

• The starter kit was sealed at delivery but contains inconsistent USB media and CoL versions.
• The License Key is reported as Invalid Signature immediately after first activation.
• ALM repeatedly returns Unknown state despite firewall verification (TCP/UDP 4410 open between client and license server).
• The distributor refuses to honor an exchange for a sealed kit shipped with superseded software, and the engineer wishes to pursue a goodwill replacement from Siemens directly.

Have the following ready when opening a Siemens support request:

• CoL scan (both sides if applicable)
• USB media version label photograph
• ALM diagnostic log (export via ALM menu: Help > Diagnostic > Save as ZIP)
• Distributor invoice number and order date
• Machine fingerprint from ALM (machine ID and host name)
