Description
Additional information

The Siemens 6AV6446-1AA41-2BB5 is a Multi Panel (MP 370) belonging to the SIMATIC HMI family, designed for demanding visualization and operator control tasks in industrial automation environments. This panel features a 12-inch TFT display and is part of Siemens' high-performance Multi Panel series, which bridges the gap between standard operator panels and full PC-based systems. It is intended for use as a human-machine interface in conjunction with Siemens SIMATIC PLCs and other compatible controllers.

The MP 370 panel is equipped with a 12-inch color TFT display with a resolution of 800 x 600 pixels (SVGA), supporting up to 256 colors. It features a resistive touch screen interface and includes a membrane keyboard for additional input flexibility. The unit communicates via MPI, PROFIBUS DP, and Ethernet interfaces, enabling integration into a wide range of network architectures. It runs on the Windows CE operating system and is configured using Siemens WinCC flexible engineering software. The panel supports a flash memory card slot for project storage and data logging.

The SIMATIC MP 370 is widely deployed in manufacturing, process automation, and machine building industries where a robust and versatile HMI solution is required. Its combination of touch and key-based input makes it suitable for applications in automotive production lines, food and beverage processing, chemical plants, and packaging machinery. The panel's compatibility with SIMATIC S7 controllers and PROFIBUS networks makes it a natural fit for existing Siemens automation architectures.

Common Error Codes & System Events

Event ID: 040000: Configuration error detected during project loading. The project file may be corrupt or incompatible with the panel firmware version.
Reload the project using WinCC flexible. Verify firmware version compatibility and re-transfer the project.
Event ID: 060000: Communication connection to the configured PLC has failed or cannot be established.
Check MPI/PROFIBUS/Ethernet cabling and termination. Verify PLC address settings match the HMI project configuration.
Event ID: 070000: Tag read/write error. The HMI cannot access a configured PLC tag or data block.
Verify the PLC data block and tag addresses in WinCC flexible. Ensure the PLC program is running and the DB exists.
Event ID: 080000: Flash memory card not detected or memory card error.
Reseat the flash memory card. Replace the card if the error persists. Ensure the card is formatted correctly for the MP 370.
Event ID: 100000: Printer communication error. The configured printer is not responding.
Check printer cable connections and printer power. Verify printer driver settings in the HMI project.
Event ID: 110000: System runtime error. An internal software fault has occurred within the Windows CE runtime environment.
Perform a warm restart of the panel. If the error persists, reload the project or perform a factory reset and re-transfer the project.
Event ID: 050000: Licence error. A required runtime licence for an advanced function is missing or invalid.
Check the licence dongle or licence file on the panel. Transfer the correct licence using the Siemens Automation License Manager.

Frequently Asked Questions

What engineering software is required to configure the MP 370 (6AV6446-1AA41-2BB5)?

The MP 370 is configured using Siemens WinCC flexible. The project is then transferred to the panel via MPI, PROFIBUS, Ethernet, or a flash memory card.

What communication interfaces are available on this panel?

The 6AV6446-1AA41-2BB5 supports MPI, PROFIBUS DP, and Ethernet (RJ45) communication interfaces, allowing connection to SIMATIC S7 PLCs and other compatible controllers.

Is this panel compatible with SIMATIC S7-300 and S7-400 PLCs?

Yes, the MP 370 is fully compatible with SIMATIC S7-300 and S7-400 PLCs via MPI or PROFIBUS DP, and can also communicate with S7 controllers over Ethernet.

What is the display size and resolution of the 6AV6446-1AA41-2BB5?

This panel features a 12-inch TFT color display with a resolution of 800 x 600 pixels (SVGA) and supports up to 256 colors.

What is the supply voltage for this HMI panel?

The MP 370 operates on a 24 V DC supply voltage, which is standard for SIMATIC HMI panels in industrial cabinet installations.

Troubleshooting

Display remains blank after power on

Check the 24 V DC supply voltage at the power connector. Verify the internal fuse is intact. Observe whether the backlight is on but the display is dark, or whether there is no power at all.

Ensure the 24 V DC supply is within tolerance. Replace the internal fuse if blown. If the backlight has failed, the display or backlight inverter board may require replacement.

Touchscreen does not respond or is misaligned

Attempt to access the panel via the Start Center using the membrane keyboard. Check whether the touch calibration has been lost or if the resistive touch surface is damaged.

Recalibrate the touchscreen through the Windows CE Control Panel or the SIMATIC HMI Start Center. If calibration does not resolve the issue, the touch overlay may need to be replaced.

Panel fails to establish communication with the PLC

Verify the MPI or PROFIBUS address settings on both the panel and the PLC. Check cable integrity and bus termination resistors. Confirm the baud rate settings match on all devices.

Correct any address or baud rate mismatches in the WinCC flexible project and PLC configuration. Replace faulty cables or connectors. Ensure proper bus termination at both ends of the PROFIBUS segment.

Project transfer fails or is interrupted

Check the transfer cable or Ethernet connection between the engineering PC and the panel. Verify the panel is in Transfer mode via the Start Center. Check for firewall or antivirus software blocking the connection on the PC.

Switch the panel to Transfer mode manually via the Start Center. Use a known-good transfer cable. Disable firewall or antivirus temporarily during transfer. Ensure WinCC flexible version is compatible with the panel firmware.

Panel reboots repeatedly or freezes during operation

Check the 24 V DC supply for voltage dips or ripple. Inspect the flash memory card for errors. Review the system event log in WinCC flexible Runtime for recurring event IDs.

Stabilize the power supply and ensure adequate current capacity. Replace the flash memory card if corrupted. Reload the project to the panel. If the issue persists, perform a factory reset and re-transfer a clean project.
