Description
Additional information

The Siemens Multi Panel MP370, part number 6AV6545-6DB10-0BS0, is a high-performance operator panel belonging to the SIMATIC HMI Multi Panel series. It features a 12.1-inch TFT color display and is designed for demanding visualization and control tasks in industrial automation environments. As part of Siemens' SIMATIC HMI portfolio, the MP370 bridges the gap between standard operator panels and full PC-based systems.

The MP370 (6AV6545-6DB10-0BS0) is equipped with a touch-sensitive screen and supports multiple communication interfaces including MPI, PROFIBUS DP, and Ethernet, enabling integration with a wide range of Siemens SIMATIC PLCs such as the S7-300 and S7-400 series. The panel runs on Windows CE and is configurable using WinCC flexible engineering software. It offers 12 MB of user memory for project data, supports recipe management, trend displays, alarm logging, and can handle complex graphical HMI applications with up to 65,536 colors.

The MP370 is widely deployed in manufacturing, process automation, machine building, and plant engineering applications where a robust, mid-to-large format operator interface is required. Its versatile communication capabilities and Windows CE-based operating environment make it suitable for integration into both new installations and retrofit projects across industries such as automotive, food and beverage, chemical processing, and packaging machinery.

Common Error Codes & System Events

Event ID: 10000: Communication error between the HMI panel and the connected PLC. The configured connection cannot be established.
Check MPI/PROFIBUS or Ethernet cable connections and termination resistors. Verify PLC address settings match the HMI project configuration. Restart both the PLC and the HMI panel.
Event ID: 10001: Connection to the PLC was interrupted during operation.
Inspect communication cables for damage or loose connections. Verify PLC is in RUN mode. Check for address conflicts on the network and re-establish the connection.
Event ID: 20000: Tag read error. The HMI panel is unable to read a configured tag from the PLC.
Verify the tag address in the WinCC flexible project matches the actual PLC data block or memory address. Check PLC program for address changes.
Event ID: 20001: Tag write error. The HMI panel is unable to write a value to the configured PLC tag.
Check that the target PLC memory area is not write-protected. Verify the tag address configuration in the HMI project and confirm the PLC is in a state that allows write access.
Event ID: 40000: Project download error. Transfer of the HMI project from the engineering PC to the panel failed.
Ensure the transfer cable is correctly connected and the panel is set to Transfer mode. Verify the correct communication interface is selected in WinCC flexible transfer settings.
Event ID: 50000: Insufficient memory. The HMI panel does not have enough free memory to load or run the current project.
Reduce the project size by removing unused images, scripts, or recipes. Perform a memory cleanup on the panel and re-download the project.
Event ID: 60000: System fault. An internal software or hardware error has occurred on the panel.
Perform a controlled restart of the panel. If the fault persists, reload the operating system using the ProSave tool and re-download the HMI project.
Event ID: 70000: Recipe data error. A recipe record could not be read from or written to the internal storage.
Check available storage space on the panel. Verify recipe configuration in WinCC flexible. Re-download the project and test recipe read/write operations.

Frequently Asked Questions

Which engineering software is used to configure the MP370?

The MP370 is configured using Siemens WinCC flexible. Projects created in WinCC flexible are transferred to the panel via MPI, PROFIBUS, Ethernet, or USB connection.

Which Siemens PLCs are compatible with the MP370?

The MP370 is compatible with SIMATIC S7-200, S7-300, and S7-400 PLCs, as well as SIMATIC S5 controllers via appropriate drivers. Communication is supported over MPI, PROFIBUS DP, and Ethernet interfaces.

What is the operating voltage of the MP370?

The MP370 operates on 24 V DC. Ensure a stable, regulated 24 V DC power supply is used to avoid panel faults or data loss.

Can the MP370 be used as a standalone panel without a PLC?

The MP370 can display static screens and run scripts without a live PLC connection, but dynamic tag-based visualization requires an active connection to a configured PLC or data source.

What is the front panel protection rating of the MP370?

The front panel of the MP370 carries an IP65 protection rating, making it suitable for installation in environments where dust and water jets may be present.

Troubleshooting

Display remains blank after power on

Measure the 24 V DC supply voltage at the power connector on the rear of the panel. Check the internal fuse if accessible. Verify the power supply can deliver sufficient current.

Replace or adjust the 24 V DC power supply if voltage is out of tolerance. If the backlight has failed, the display panel or backlight inverter may need replacement. Perform a hard reset by cycling power.

HMI panel fails to communicate with the PLC

Check the MPI, PROFIBUS, or Ethernet cable connections at both the panel and PLC ends. Verify the bus address configured in the HMI project matches the physical PLC address. Use a bus diagnostic tool to check for network errors.

Replace faulty communication cables. Correct address mismatches in the WinCC flexible project and re-download. Ensure PROFIBUS termination resistors are correctly placed at both ends of the bus.

Touchscreen does not respond or responds inaccurately

Inspect the touchscreen surface for damage, contamination, or excessive pressure. Check if the issue is consistent across the entire screen or localized to specific areas.

Clean the touchscreen surface with a soft, lint-free cloth. Perform a touchscreen recalibration through the panel's Control Panel settings under Windows CE. If calibration does not resolve the issue, the touchscreen overlay may require replacement.

Project transfer from PC to panel fails

Verify the panel is set to Transfer mode via the Start Center. Check that the correct communication interface (Ethernet, MPI, or PROFIBUS) is selected in WinCC flexible transfer settings and that the IP address or bus address is correctly configured.

Restart the panel in Transfer mode and retry the download. If using Ethernet, confirm the PC and panel are on the same subnet. For MPI/PROFIBUS transfers, ensure the PC adapter (e.g., PC Adapter USB) is correctly installed and configured.

Panel repeatedly restarts or freezes during operation

Check the 24 V DC supply for voltage drops or ripple, which can cause instability. Review the alarm log for recurring system event codes. Inspect the panel for signs of overheating by checking ambient temperature and ventilation around the enclosure.

Stabilize the power supply and ensure adequate ventilation. If the issue persists, reload the Windows CE operating system using the Siemens ProSave tool, then re-download the HMI project. If hardware faults are suspected, the unit should be sent for repair or replacement.
