Description
Additional information

The Siemens 6AV6645-0EB01-0AX1 is a Multi Panel (MP 377) belonging to the SIMATIC HMI family, designed for demanding machine-level visualization and operator control tasks. This panel features a 15-inch TFT display and is part of the MP 377 series, which represents Siemens' high-performance panel range for industrial human-machine interface applications. It operates as a standalone HMI device capable of running WinCC flexible runtime environments.

The 6AV6645-0EB01-0AX1 is equipped with a resistive touchscreen and an additional membrane keyboard, providing flexible operator input options. It features a 1 GHz processor with 128 MB RAM and 128 MB flash memory, enabling smooth runtime performance for complex visualization projects. Communication interfaces include PROFINET (Ethernet), MPI/PROFIBUS DP, and USB ports, allowing integration into a wide range of Siemens and third-party automation architectures. The panel supports WinCC flexible 2008 and can be configured using the SIMATIC WinCC flexible engineering software.

The MP 377 15" Touch is widely deployed in manufacturing, automotive, food and beverage, and process industries where a large, high-resolution display is required for complex process visualization. Its robust industrial housing and broad communication capability make it suitable for integration into SIMATIC S7-300 and S7-400 PLC environments. The panel is also used in applications requiring simultaneous display of multiple process values, alarm management, and recipe handling.

Common Error Codes & System Events

Event ID: 10000: Connection to PLC lost or communication timeout on configured connection.
Check PROFINET or MPI/PROFIBUS DP cable connections, verify PLC is powered and running, and confirm network address settings in the project configuration.
Event ID: 10001: Connection to PLC established after a previous failure.
Informational event. No corrective action required; verify stable network conditions to prevent recurrence.
Event ID: 20000: Tag read error — the HMI panel cannot read a configured tag from the PLC.
Verify the tag address exists in the PLC program, check data block availability, and confirm correct data type mapping in WinCC flexible.
Event ID: 40000: System memory low — available runtime memory is critically low.
Reduce the number of active screens, limit logged data, or optimize the WinCC flexible project to reduce memory usage.
Event ID: 50000: Data record (recipe) transfer error between HMI and PLC.
Check recipe configuration, verify PLC data block addresses match recipe element assignments, and ensure PLC is in RUN mode.
Event ID: 70000: Backup or restore operation failed on the panel.
Check the USB storage device for sufficient space and correct formatting (FAT32), then retry the backup or restore procedure via the Control Panel.
Event ID: 80000: Project download failed or project file is incompatible with panel firmware version.
Verify the WinCC flexible version matches the panel firmware. Update panel firmware via ProSave if necessary, then re-download the project.

Frequently Asked Questions

What engineering software is required to configure the MP 377 15" Touch?

The MP 377 is configured using Siemens WinCC flexible 2008 or later. Projects are downloaded to the panel via Ethernet (PROFINET) or USB connection using the ProSave tool or directly from within WinCC flexible.

Which PLCs are compatible with the Siemens 6AV6645-0EB01-0AX1?

The MP 377 is compatible with SIMATIC S7-300, S7-400, S7-1200, and S7-1500 PLCs via PROFINET or MPI/PROFIBUS DP. It also supports connections to third-party controllers using standard communication drivers available in WinCC flexible.

What is the supply voltage for the 6AV6645-0EB01-0AX1?

The panel requires a 24 V DC power supply. It is recommended to use a regulated SELV power supply meeting IEC 60364-4-41 requirements.

Can the MP 377 display be operated by touch only, or is a keyboard required?

The 6AV6645-0EB01-0AX1 variant includes both a resistive touchscreen and a membrane keyboard, so it can be operated via touch alone or using the keyboard keys depending on the application design.

What is the maximum number of tags supported at runtime on the MP 377?

The MP 377 supports up to 2,048 external tags (process tags) at runtime when configured with WinCC flexible, making it suitable for complex visualization projects with large numbers of process variables.

Troubleshooting

Display remains blank after power is applied

Measure 24 V DC at the power supply connector on the rear of the panel. Check that the voltage is within the acceptable range (20.4–28.8 V DC). Inspect the internal fuse if accessible.

Ensure the power supply is correctly rated and stable. If voltage is correct but the display remains off, the backlight or internal power board may be faulty and the panel should be sent for repair or the backlight replaced.

Touchscreen does not respond or responds inaccurately

Determine whether the issue is with the resistive touch layer or the controller. Access the Control Panel on the panel and run the touch calibration utility. Check for physical damage or contamination on the screen surface.

Perform a touch recalibration via Start > Control Panel > Touch on the panel OS. If calibration does not resolve the issue, the touch overlay may need replacement. Clean the screen surface with a soft, dry cloth.

HMI cannot establish communication with the PLC

Verify the PROFINET or MPI/PROFIBUS DP cable is correctly connected and undamaged. Check the IP address or MPI address configured in the HMI project matches the PLC settings. Use a network diagnostic tool to confirm network reachability.

Correct any IP address or MPI address mismatches in the WinCC flexible project and re-download. Replace faulty cables or connectors. Ensure the PLC is in RUN mode and the relevant communication interface is enabled.

Panel repeatedly reboots or freezes during operation

Check for unstable 24 V DC power supply voltage, especially under load. Review the system event log on the panel for memory or runtime errors. Determine if the issue is project-related by loading a minimal test project.

Replace or stabilize the power supply. Optimize the WinCC flexible project to reduce CPU and memory load. If the problem persists with a minimal project, the panel hardware may require servicing or the firmware should be updated using ProSave.

Project download fails from WinCC flexible engineering station

Verify the Ethernet connection between the PC and the panel. Confirm the panel IP address is reachable by pinging it from the engineering PC. Check that the WinCC flexible version is compatible with the panel firmware version.

Update the panel firmware to match the WinCC flexible version using the ProSave tool. Ensure no firewall is blocking the transfer port. If using USB for transfer, try switching to Ethernet or vice versa.
