Description
Additional information

The Siemens MP 370 (part number 6AV6545-0AH10-0AX0) is a Multi Panel HMI device belonging to the SIMATIC HMI Multi Panel family. It features a 12-inch TFT display and is designed for demanding machine-level visualization and operator control tasks. As part of Siemens' established SIMATIC HMI portfolio, it bridges the gap between compact operator panels and full PC-based visualization systems.

The 6AV6545-0AH10-0AX0 variant 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 S7 PLCs and third-party controllers. The panel runs on Windows CE and is configured using WinCC flexible engineering software. It offers onboard Flash memory for project storage and supports USB and CompactFlash interfaces for data archiving and project transfer. The unit operates on 24 V DC supply and is rated to IP65 on the front face for protection against dust and water ingress.

The MP 370 is widely deployed in manufacturing, automotive, food and beverage, and process industries where a robust, mid-size HMI with reliable communication to SIMATIC controllers is required. Its compatibility with PROFIBUS DP makes it suitable for distributed automation architectures, while its touch interface allows intuitive operator interaction on the machine front panel. The panel is typically flush-mounted into control cabinet doors or operator stations.

Common Error Codes & System Events

Event ID: 10000: Communication error between HMI panel and PLC. Connection to the configured controller cannot be established or has been lost.
Check MPI/PROFIBUS or Ethernet cable connections and termination resistors. Verify PLC address settings match the HMI project configuration. Restart both PLC and HMI panel.
Event ID: 10001: Tag read error. The HMI panel cannot read a configured tag from the PLC.
Verify the tag address exists in the PLC program and the data block is not write-protected. Check communication settings and ensure the PLC program is loaded and running.
Event ID: 10002: Tag write error. The HMI panel cannot write a value to the configured PLC tag.
Check that the target address in the PLC is not read-only or protected. Verify communication link integrity and PLC operating mode (must be in RUN mode for write access).
Event ID: 20000: Project loading error. The HMI project file could not be loaded from Flash or CompactFlash memory.
Re-transfer the project from the engineering PC using WinCC flexible. Check CompactFlash card for errors or replace if faulty.
Event ID: 40000: System memory low. Available RAM on the Windows CE system is critically low.
Reduce the number of open screens or active alarms. Restart the panel to free memory. Simplify the HMI project if the issue persists.
Event ID: 70010: Printer error. The configured printer is not responding or is unavailable.
Check printer connection and power. Verify printer driver settings in the HMI project. Restart the panel and printer.
Event ID: 50000: Recipe data error. A recipe record could not be read or written correctly.
Check the recipe configuration in WinCC flexible. Verify that the CompactFlash card has sufficient free space and is not write-protected.

Frequently Asked Questions

Which engineering software is used to configure the MP 370 (6AV6545-0AH10-0AX0)?

The MP 370 is configured using Siemens WinCC flexible. Projects are compiled and transferred to the panel via Ethernet, USB, or MPI connection from the engineering PC.

Which PLCs are compatible with the Siemens MP 370?

The MP 370 is primarily designed for use with Siemens SIMATIC S7-300 and S7-400 PLCs via MPI or PROFIBUS DP. It also supports Ethernet-based communication with S7 controllers and can communicate with third-party controllers via serial interfaces.

What is the display size and resolution of the 6AV6545-0AH10-0AX0?

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

What is the supply voltage for the MP 370?

The MP 370 operates on a 24 V DC supply voltage. Ensure a stable, regulated 24 V DC power source is used to avoid panel instability.

Can the MP 370 be used with PROFIBUS DP networks?

Yes, the MP 370 supports PROFIBUS DP communication, allowing it to be integrated into distributed automation systems alongside SIMATIC S7 PLCs and other PROFIBUS-compatible devices.

Troubleshooting

Display remains blank after power on

Check that 24 V DC supply voltage is present at the power connector. Measure voltage at the panel terminals. Check internal fuse if accessible.

Ensure the power supply is providing stable 24 V DC within the specified tolerance. Replace the power supply or internal fuse if voltage is absent. If voltage is correct but display remains blank, the backlight or internal power board may require replacement.

HMI panel cannot establish communication with the PLC

Verify the MPI or PROFIBUS DP cable is correctly connected and terminated. Check that the bus address configured in the HMI project matches the physical PLC address. Use a bus diagnostic tool to check network integrity.

Correct any address mismatches in the WinCC flexible project. Replace or re-terminate the communication cable. Ensure termination resistors are active only at both ends of the bus segment.

Touch screen does not respond or responds inaccurately

Check for physical damage or contamination on the touch surface. Attempt a touch screen recalibration via the Windows CE Control Panel or the SIMATIC HMI startup menu.

Clean the touch surface with a soft, dry cloth. Perform touch screen recalibration from the panel's system settings. If calibration does not resolve the issue, the touch overlay may need to be replaced.

Project transfer from WinCC flexible fails

Verify the communication channel between the engineering PC and the panel (USB, Ethernet, or MPI). Check 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 startup menu. Disable firewall or antivirus temporarily during transfer. Ensure the correct communication channel and IP address or MPI address are configured in WinCC flexible.

Panel repeatedly restarts or crashes during operation

Check for unstable 24 V DC supply voltage. Review the HMI project for memory-intensive screens or excessive tag polling rates. Check CompactFlash card for errors.

Stabilize the power supply and ensure it is adequately rated for the panel's power consumption. Optimize the WinCC flexible project by reducing polling rates and screen complexity. Replace the CompactFlash card if file system errors are detected.
