Description
Additional information

The Siemens 6AV2123-2MA03-0AX0 is a KTP1200 Basic Panel belonging to the SIMATIC HMI Basic Panel series by Siemens. It is a 12-inch key and touch-operated HMI panel designed for straightforward machine-level visualization and operator control tasks. This panel provides a cost-effective solution for applications requiring a mid-size display with reliable performance in industrial environments.

The KTP1200 Basic features a 12.1-inch widescreen TFT display with a resolution of 1280 x 800 pixels and 64,000 colors, delivering clear and detailed process visualization. It supports PROFINET communication as the primary interface for integration with Siemens S7-1200 and S7-1500 PLCs, as well as other PROFINET-compatible controllers. The panel includes 10 configurable function keys, a resistive touch screen, and is configured using Siemens WinCC Basic or WinCC Comfort engineering software via TIA Portal. It operates on a 24 V DC supply and carries CE and UL certifications.

The KTP1200 Basic Panel is widely used in machine building, packaging machinery, conveyor systems, and general factory automation where a robust mid-size HMI is required. Its PROFINET connectivity and TIA Portal integration make it particularly suitable for systems built around Siemens S7-1200 and S7-1500 controller platforms. The panel's IP65 front protection rating makes it appropriate for installation in control cabinet doors exposed to dust and water spray in industrial production environments.

Common Error Codes & System Events

Event ID: 10000: Configuration error: The project loaded on the panel is incompatible or corrupt.
Re-download the project from TIA Portal to the panel. Verify the WinCC version matches the panel firmware version.
Event ID: 20000: Communication error: Connection to the PLC has been lost or cannot be established.
Check PROFINET cable connections and IP address configuration. Verify the PLC is in RUN mode and the network settings match the project configuration.
Event ID: 40000: Tag update error: A configured tag cannot be read from or written to the controller.
Verify the tag address exists in the PLC program. Check data type compatibility between the HMI tag and the PLC variable.
Event ID: 50000: Licence error: Required runtime licence is missing or invalid.
Check the licence status in TIA Portal. Transfer a valid licence to the panel using the Automation License Manager.
Event ID: 70000: System memory low: Available runtime memory on the panel is insufficient.
Reduce the number of active screens, images, or logged data. Optimize the project in TIA Portal to reduce memory usage.
Event ID: 110000: Firmware update error: A firmware update was interrupted or failed to complete.
Retry the firmware update using ProSave or TIA Portal. Ensure stable power supply during the update process and verify the correct firmware file is used.
Event ID: 130000: Recipe data error: Recipe records cannot be read or written correctly.
Check the recipe configuration in TIA Portal. Verify that the recipe data memory has not been corrupted and re-download the project if necessary.

Frequently Asked Questions

Which PLCs are compatible with the KTP1200 Basic panel 6AV2123-2MA03-0AX0?

The KTP1200 Basic is primarily designed for use with Siemens S7-1200 and S7-1500 PLCs via PROFINET. It can also communicate with other PROFINET-capable controllers when configured appropriately in TIA Portal.

What engineering software is required to configure this panel?

The 6AV2123-2MA03-0AX0 is configured using Siemens TIA Portal with WinCC Basic or WinCC Comfort. WinCC Basic is included with STEP 7 Basic, while WinCC Comfort is required for advanced functionality.

What is the supply voltage for the KTP1200 Basic?

The panel operates on a 24 V DC supply voltage. A stable, regulated 24 V DC power supply must be provided for correct operation.

Does the KTP1200 Basic support USB connectivity?

Yes, the KTP1200 Basic includes a USB Type-A port for connecting peripherals such as keyboards or barcode scanners, and a USB Mini-B port used for project transfer and service purposes.

What is the front protection rating of this panel?

The front of the KTP1200 Basic panel carries an IP65 protection rating, making it suitable for installation in cabinet doors where it may be exposed to dust and water spray.

Troubleshooting

Display remains blank after power is applied

Measure the 24 V DC supply voltage at the panel's power connector. Check that the voltage is within the specified range and that polarity is correct.

Correct any wiring errors or supply voltage issues. If the supply voltage is confirmed correct and the display remains blank, the internal power supply or backlight may be faulty and the panel should be sent for repair or replacement.

Panel cannot establish communication with the PLC

Verify the PROFINET cable is connected to the correct port and check the IP address settings on both the panel and the PLC. Use a network diagnostic tool to confirm the panel is visible on the network.

Correct the IP address, subnet mask, and gateway settings in TIA Portal and re-download the project. Replace the PROFINET cable if a physical fault is suspected.

Touchscreen does not respond or responds inaccurately

Check whether the touch function is disabled in the panel settings. Inspect the screen surface for damage, contamination, or excessive pressure points.

Clean the screen surface with a soft, dry cloth. If the touch response is inaccurate, perform a touch screen calibration via the panel's Start Center. If the issue persists, the touch foil may require replacement.

Project download from TIA Portal fails

Check the communication connection between the engineering PC and the panel, either via PROFINET or USB. Verify that the panel is in transfer mode and that firewall or antivirus software is not blocking the connection.

Set the panel to transfer mode via the Start Center. Disable any firewall or security software temporarily during transfer. Ensure the TIA Portal version is compatible with the panel firmware version, and update the firmware if necessary.

Panel displays 'No project' or resets to Start Center after power cycle

This indicates the project was not successfully stored in the panel's internal flash memory, or the memory has been corrupted.

Re-download the project from TIA Portal to the panel. Ensure the download completes fully before cycling power. If the problem recurs, perform a factory reset via the Start Center and re-download the project.
