Description
Additional information

The Siemens 6AV6446-1BA41-2BA3 is a Multi Panel (MP 370) belonging to the SIMATIC HMI Multi Panel series by Siemens. It is a high-performance operator panel designed for demanding visualization and control tasks in industrial automation environments. The MP 370 features a 12-inch TFT display and is part of the SIMATIC HMI product line, which integrates seamlessly with Siemens SIMATIC PLCs and automation systems.

The 6AV6446-1BA41-2BA3 is equipped with a 12.1-inch TFT color display with a resolution of 800 x 600 pixels (SVGA) and supports touch screen operation. It runs on the Windows CE operating system and includes WinCC flexible runtime software for HMI configuration and visualization. The panel provides multiple communication interfaces including MPI, PROFIBUS DP, and Ethernet (TCP/IP), enabling flexible integration into existing automation networks. It offers 12 MB of user memory for project data and supports USB ports for peripheral connectivity and data transfer.

The SIMATIC MP 370 is widely used in machine building, automotive manufacturing, process industries, and factory automation applications. Its robust industrial design and broad communication capability make it suitable for use as a central operator interface on complex machinery, production lines, and process control systems. The panel is particularly valued in applications requiring simultaneous visualization of multiple data sources and integration with SIMATIC S7 controller families.

Common Error Codes & System Events

Event ID: 10000: Communication error between HMI panel and PLC. The configured connection to the controller cannot be established or has been lost.
Check physical connections (MPI/PROFIBUS/Ethernet cable). Verify PLC address and communication parameters in the WinCC flexible project. Ensure the PLC is powered and in RUN mode.
Event ID: 10001: Connection to PLC interrupted during runtime. The HMI panel lost communication with the configured controller.
Inspect cabling and connectors for damage. Check bus termination resistors on PROFIBUS segments. Restart both the HMI panel and the PLC and monitor for recurrence.
Event ID: 20000: Project download error. The project could not be transferred to the HMI panel successfully.
Verify the transfer cable or Ethernet connection between the engineering PC and the panel. Ensure sufficient free memory on the panel. Retry the download after restarting the panel in transfer mode.
Event ID: 40000: System memory low. Available memory for runtime operation is critically low.
Reduce the project size by removing unused screens or data logs. Delete unnecessary files from the panel memory. Consider archiving or offloading data logs to an external storage device.
Event ID: 50000: Internal system error. A runtime fault has occurred within the WinCC flexible runtime environment.
Restart the HMI panel. If the error persists, reload the project from the engineering station. Check for WinCC flexible runtime software version compatibility.
Event ID: 70000: Recipe data error. A fault occurred during reading or writing of recipe data.
Check the recipe configuration in WinCC flexible. Verify that the recipe data record is not corrupted. Re-transfer the project and test recipe operations.
Event ID: 30000: Tag read/write error. A configured tag could not be read from or written to the PLC.
Verify the tag address in the WinCC flexible project matches the actual PLC data block or memory area. Check PLC program for address conflicts. Confirm the PLC is not in STOP mode.

Frequently Asked Questions

What communication interfaces are available on the 6AV6446-1BA41-2BA3?

The MP 370 supports MPI, PROFIBUS DP, Ethernet (TCP/IP), and RS-422/485 interfaces, allowing connection to a wide range of Siemens SIMATIC PLCs and third-party controllers.

Which Siemens PLCs are compatible with the SIMATIC MP 370?

The MP 370 is compatible with the SIMATIC S7-200, S7-300, S7-400, and S7-1200 controller families when configured with the appropriate communication drivers in WinCC flexible.

What software is used to configure and program the MP 370?

The MP 370 is configured using Siemens WinCC flexible engineering software. Projects are created on a PC and downloaded to the panel via MPI, Ethernet, or USB.

What is the display type and resolution of the 6AV6446-1BA41-2BA3?

This unit features a 12.1-inch TFT color display with a resolution of 800 x 600 pixels (SVGA) and resistive touch screen operation.

What is the supply voltage requirement for the MP 370?

The SIMATIC MP 370 requires a 24 V DC supply voltage for operation.

Troubleshooting

Display remains blank after power on

Check the 24 V DC supply voltage at the power connector. Verify that the power LED is illuminated. Measure voltage at the input terminals to confirm supply is within specification.

Ensure the 24 V DC supply is stable and within the specified range. Replace the power supply if voltage is absent or out of tolerance. If supply is correct, the internal power board or backlight inverter may require replacement.

HMI panel fails to communicate with SIMATIC S7 PLC via PROFIBUS

Inspect the PROFIBUS cable and connectors for damage or incorrect termination. Verify the bus address configured on the panel matches the project settings. Check that bus termination is active only at both physical ends of the PROFIBUS segment.

Correct any wiring faults and ensure proper bus termination. Adjust the PROFIBUS address in the WinCC flexible project if there is a mismatch. Restart both devices after making corrections.

Touch screen does not respond or responds inaccurately

Check the touch screen surface for contamination or physical damage. Attempt to recalibrate the touch screen through the panel's Control Panel settings in Windows CE.

Clean the touch screen surface with a soft, dry cloth. Perform a touch screen recalibration via the Windows CE Control Panel. If the issue persists, the touch screen overlay may need to be replaced.

Project cannot be downloaded to the panel

Verify that the panel is set to Transfer mode. Check the communication cable or Ethernet connection between the engineering PC and the panel. Confirm that the correct transfer channel is selected in WinCC flexible.

Switch the panel to Transfer mode via the Start Center menu. Use a known-good MPI or Ethernet cable. Ensure the PC firewall is not blocking the transfer and that the correct IP address or MPI address is configured in the project.

Panel restarts repeatedly or freezes during runtime

Check for corrupted project data by reviewing the event log. Verify that the panel memory is not full. Inspect the 24 V DC supply for voltage fluctuations or noise.

Reload the project from the engineering station to overwrite potentially corrupted runtime data. Free up panel memory by removing unused files. Install a stable, regulated 24 V DC power supply and add filtering if electrical noise is suspected.
