TIA Portal V16: Fixing KTP400 Basic Panel Image Download Error

Problem Summary

When a TIA Portal V16 project is compiled and downloaded to a SIMATIC KTP400 Basic panel, the engineering workstation aborts the transfer during the OS transfer phase with the dialog:

"Download to device failed due to missing panel: image components with a different version are installed on the target device."

The error is generated by the WinCC component of TIA Portal V16 (builds 16.0.0.1900 through 16.0.0.2200) and prevents any project image from being committed to the panel. The panel continues running with its previous image; the new configuration is not loaded. The error is independent of the PLC program download, which can still succeed in the same session because the HMI transfer and PLC transfer are handled as separate, sequential operations.

Three field scenarios produce the error consistently:

1. A 2nd-generation KTP400 Basic (article number 6AV2123-2DB03-0AX0) is being commissioned for the first time on a workstation where TIA Portal V16 was installed but the 2nd-generation Basic Panel image components were not selected during setup. This is the most common cause in greenfield projects.
2. An existing project was upgraded from TIA Portal V13 SP1 / V14 / V15.x to V16, and the local HMI image repository still contains only the previous image set. TIA Portal V16 does not automatically backfill missing image files when an older installation is upgraded; the new image set must be added explicitly.
3. The panel was previously updated with a ProSave image sourced from a WinCC version that does not match the active TIA Portal V16 installation (for example, a WinCC V15.1 image pushed to the panel while the engineering station is running V16).

Error Message Anatomy

The same underlying condition surfaces as one of several dialog texts depending on the transfer path, the build of TIA Portal V16, and the localization of the engineering software. Treat each form as the same fault and follow the same procedure.

Across all five forms the underlying condition is identical: the WinCC image components present on the panel do not match the WinCC image components bundled with the TIA Portal installation on the engineering station. TIA Portal refuses to write a project image on top of a mismatched runtime to prevent the panel from being left in an unbootable state, so the transfer is rejected before any project data is written.

Root Cause: Image Component Version Mismatch

Each TIA Portal / WinCC release ships a set of panel image files. The image is the runtime OS plus the configuration, runtime, and option handlers that the panel boots before loading the project. The image file is stored locally on the engineering workstation and written to the panel during the first download of any project that targets a given panel type.

For TIA Portal V16, the image is keyed to the WinCC build number 16.0.0.x. The 2nd-generation Basic Panels (KTP400 Basic, KTP700 Basic, KTP900 Basic, KTP1200 Basic) require a dedicated image set that was added to the WinCC installer in V14 SP1 and updated through V15.1, V16, V17, and beyond. If the TIA Portal V16 setup was customized to exclude the optional 2nd-generation components (a common practice on locked-down corporate images, particularly on plants that have standardized on Comfort Panels), the V16 image directory will be incomplete and the project will compile cleanly but fail at the transfer stage.

The relevant local paths on a default TIA Portal V16 installation are:

• Engineering image repository: C:\Program Files\Siemens\Automation\Portal V16\Hmi\Images
• WinCC image cache: %ProgramData%\Siemens\Automation\Portal V16\Hmi\Images
• Per-device image subfolder (2nd generation): ...\Hmi\Images\KTP400_Basic\
• Per-device image subfolder (1st generation, legacy): ...\Hmi\Images\KTP400_Basic_1st\

TIA Portal indexes the image cache on service start and on every Compile → Software (rebuild all) operation. If the index lists a device type for which no image files are present, the compile finishes without error (because the project itself is valid) but the download fails with the message in this article.

Affected Hardware and Identification

Determine the generation of the panel before continuing. The KTP400 Basic was released in two generations with different WinCC image requirements. Image sets are not interchangeable between generations.

To confirm the panel in hand:

1. Read the article number on the rear label. The block after the second dash (2DB01 vs. 2DB03) is the generation key. 2DB01 = 1st generation, 2DB03 = 2nd generation.
2. Power the panel, open the Control Panel via the Start button, and navigate to System → About. The displayed firmware version begins with V16.0.0.x for a V16 image, V15.1.0.x for a V15.1 image, V14.0.0.x for a V14 SP1 image.
3. Open the TIA Portal project, select the HMI device in the project tree, and check Device Properties → General → Device Version. The article number shown here must match the physical label exactly, including the trailing 0AX0 suffix.
4. Cross-check the article against the device catalog using the Siemens Industry Online Support catalog search. The catalog is the authoritative source for the article number, current firmware, and EOL status.

If the project specifies a 1st generation panel and the physical unit is a 2nd generation (or vice versa), no image match is possible. Replace the device in the project with the correct article number rather than attempting to reflash across generations.

Required Image Files by Panel Generation

The image set required for a 2nd-generation KTP400 Basic in TIA Portal V16 consists of the following files. All are placed under ...\Hmi\Images\KTP400_Basic\ on the engineering workstation.

For 1st generation panels, the equivalent files use the .im13 extension and are stored under ...\Hmi\Images\KTP400_Basic_1st\. The 1st generation image is no longer shipped with the TIA Portal V16 installation and must be sourced from a V13 / V14 SP1 install media if a V16 project must talk to a 1st generation unit in compatibility mode.

TIA Portal V16 (6ES7822-0AA06-0YA5) DVD Layout and "DVD 3" History

Software product 6ES7822-0AA06-0YA5 is the SIMATIC WinCC V16 engineering package (Basic / Comfort / Advanced editions bundled on a single media set). The media set comprises two physical DVDs:

The reference to "DVD 3" in older Siemens installation notes comes from the pre-V14 layout, when a third disk was required for 2nd-generation Basic Panel image components. From V14 SP1 onward, all 2nd-generation components are bundled on the second disk, so a "DVD 3" is no longer shipped. A delivery of 6ES7822-0AA06-0YA5 containing only DVD 1/2 and DVD 2/2 is complete and correct.

For confirmation, refer to the official Siemens Industry Online Support entry "Image downloads for HMI operator panels". The article lists the latest image bundles for all supported panel families and confirms that 2nd-generation Basic Panel images are part of the V16 base installer. The article also serves as the authoritative source for the most recent maintenance update to each image — a V16 service pack may refresh the .im16 file without a full TIA Portal reinstall.

Step-by-Step: Install Missing Panel Image Files

If the panel image components were not selected during the original TIA Portal V16 setup, install them now without uninstalling the rest of the package. The setup re-entry path is non-destructive to existing projects.

Prerequisites

• Local administrator rights on the engineering workstation.
• Access to the original installation media (DVD 2/2 of 6ES7822-0AA06-0YA5), or the corresponding download package from Siemens Online Support.
• TIA Portal V16 must be closed before the setup change; the setup tool refuses to modify the installation if the WinCC editor is running.
• At least 2 GB of free disk space on the system partition.

Procedure

1. Insert DVD 2/2 (or mount the ISO). The TIA Portal V16 setup should auto-launch. If it does not, run Setup.exe from the root of the disk.
2. On the Product Language page, leave the existing selection and click Next. The language list is locked to the originally installed set; adding a new language requires a separate setup pass.
3. On the Product Selection page, expand WinCC V16 → HMI Software → Images. Locate the entry KTP400 Basic 2nd Generation Image (V16.0.0.x). Change the install action from Not installed to Install on local hard drive.
4. Repeat the same step for any other panel images that will be needed, for example KTP700 Basic 2nd Generation, KTP900 Basic 2nd Generation, KTP1200 Basic 2nd Generation, and the Comfort Panel images if Comfort-edition projects are also present.
5. Accept the license agreement and click Install. The setup rewrites only the selected components; the TIA Portal configuration database, the options catalog, and existing projects are not touched.
6. When the setup completes, click Finish and restart the engineering station. The WinCC image cache is re-indexed during the next service start; rebooting forces the index to be rebuilt from the new files.

Verification

1. Open Windows Explorer and navigate to C:\Program Files\Siemens\Automation\Portal V16\Hmi\Images\KTP400_Basic\.
2. Confirm the file KTP400_Basic_V16.im16 is present and sized at approximately 85 MB.
3. Open TIA Portal V16, right-click the KTP400 Basic device in the project tree, and choose Compile → Software (rebuild all). The compile must complete without warnings about missing image components.

Step-by-Step: Configure and Download in TIA Portal

Once the image is in place, repeat the download to recover from the failed transfer.

1. Open the project in TIA Portal V16. Select the KTP400 Basic device in the project tree.
2. Open Online → Extended Download to Device. Confirm the interface (PN/IE or PROFIBUS), the subnet, and the target panel IP address. The default IP for an out-of-the-box 2nd-generation KTP400 Basic is 192.168.0.10; the engineering station must be on the same subnet.
3. If the PG/PC interface is not yet set, choose PG/PC Interface from the Online menu and select the network adapter bound to the HMI subnet. Use the S7ONLINE access point for PROFINET transfers.
4. Click Search. TIA Portal scans the subnet and lists compatible HMI devices. Highlight the target KTP400 Basic. If the device does not appear, ping the panel IP from a command prompt to confirm L2/L3 connectivity, and verify that the panel's PROFINET interface is not set to a different subnet.
5. Select the device and click Load. The Load Preview dialog opens. Tick Overwrite all for the HMI image. Click Load.
6. TIA Portal now performs a three-step transfer: (1) image transfer (~4 minutes), (2) project transfer (~30 seconds), (3) project activation (~10 seconds). The total time for a 2nd-generation KTP400 Basic is typically 5-7 minutes over PROFINET at 100 Mbit/s.
7. When the Load Results dialog reports success, click Finish. The panel reboots into the new image and starts the runtime.

Alternative Procedure: Image Update via ProSave / SIMATIC Automation Tool

If the local image cache cannot be rebuilt, or if the panel is unreachable from TIA Portal due to a corrupted image, restore the panel directly from a Windows host using ProSave V16 or the SIMATIC Automation Tool V16. Both tools are bundled on DVD 2/2 of 6ES7822-0AA06-0YA5.

Prerequisites

• ProSave V16 (installed from the same DVD 2/2 as TIA Portal) or SIMATIC Automation Tool V16.
• Ethernet connection between the engineering station and the panel, with both ends on the same subnet.
• A valid image file KTP400_Basic_V16.im16 located on the engineering station. The file can be copied from the image cache of a working TIA Portal V16 installation or downloaded from the Siemens "Image downloads for HMI operator panels" support entry.
• Panel Control Panel — if accessible, disable the transfer password under System → Transfer to avoid an authentication prompt during the OS update.

Procedure with ProSave V16

1. Launch ProSave V16. From the Panel type dropdown select KTP400 Basic.
2. Set Connection type to Ethernet. Enter the panel IP address (default 192.168.0.10).
3. Click Connect. ProSave reads the current image version from the panel and displays it under Panel image version.
4. Switch to the OS Update tab. Tick Update the operating system and select Use file. Browse to KTP400_Basic_V16.im16.
5. Tick Reset to factory settings only if the project must be wiped. Otherwise, leave it unticked to preserve the existing project after the image is updated.
6. Click Execute. The image is pushed to the panel. Progress is shown in the status bar; the operation takes 4-8 minutes depending on the network speed.
7. When the update completes, ProSave prompts to reboot the panel. Click Yes. The panel comes back online with the new image.

Procedure with SIMATIC Automation Tool V16

1. Launch the SIMATIC Automation Tool V16 and scan the subnet for HMI devices.
2. Right-click the KTP400 Basic and select Operating System Update.
3. Browse to the image file. Confirm the action and click Execute.
4. The tool updates the image in the background. After the panel reboots, proceed with a TIA Portal project download as described in the previous section.

Use the SIMATIC Automation Tool when multiple panels must be updated in a single batch — it can push a V16 image to dozens of HMIs from a CSV-driven device list, while ProSave is single-device only.

Network Configuration for HMI Download

A failed image transfer is often misdiagnosed as a missing image when the real fault is a network configuration mismatch. Validate the following points before assuming the image is the cause.

For cross-subnet transfers (panel on a different VLAN from the engineering station) configure a PROFINET IO router or use the panel's MAC address with ARP-based discovery. Direct IP search across subnets is not supported.

Firmware Compatibility Matrix

Compatibility between the engineering image and the panel firmware is strict. Mismatches always trigger the error described in this document. The matrix below covers the panels most often confused in field service.

Upward migration of a V15.1 project to V16 is supported without re-engineering, but TIA Portal V16 must rebuild the image when the project is opened for the first time. If the V16 image components are missing locally, the rebuild fails and the error in this document is generated on the next download attempt. For mixed-generation plants, install all required image sets in a single TIA Portal setup pass to eliminate future setup re-runs.

Verification and Acceptance Test

After the load completes, validate the panel is running the correct image and project before handing the system back to operations.

1. On the panel, open the Control Panel via the Start button (or the Control Panel icon on the project screen).
2. Navigate to System → About. Confirm the firmware version is 16.0.0.x and matches the TIA Portal build on the engineering station.
3. Open System → Status. Confirm the project name, project author, and last-modified date match the source project in TIA Portal.
4. On the engineering station, in TIA Portal V16, choose Online → Online & Diagnostics for the panel. The device must respond to the diagnostics request without error and the diagnostics buffer must be empty.
5. On the engineering station, open the project and select Online → Go online for both the PLC and the HMI. The online view must show consistent tag values and no diagnostic interrupts.
6. Force a tag change on the PLC side and verify the value updates on the HMI screen within the configured update time (default 1 s).
7. Trigger a screen change on the HMI via a configured button and confirm the screen change logs in the TIA Portal HMI trace (enable via Project → HMI trace if not already active).

If any of the above checks fail, return to the Step-by-Step procedure and confirm the image is on disk, the panel generation matches the project, and the network is reachable.

Related Errors, Variations, and Field-Proven Pitfalls

The same root cause produces several related messages and field pitfalls. Treat them with the same procedure.

Field-proven pitfall: corporate image management tools (SCCM, Tanium, Intune) sometimes push a "clean" Windows profile that strips the TIA Portal image cache between sessions. If the image directory is empty after a reboot, the cache will not be regenerated by TIA Portal alone — the image components must be reinstalled through the TIA Portal setup. Configure an exclusion list on the corporate image tool to protect C:\Program Files\Siemens\Automation\Portal V16\Hmi\.

Field-proven pitfall: image files copied from a colleague's workstation across the network share sometimes fail to install due to NTFS permission inheritance breaking on the new host. Always run the TIA Portal setup from local media or a properly staged network share, never by dragging the image files into the cache directory directly.
