Additional information

The Siemens Multi Panel MP 377 (part number 6AV6644-5AB10-0BS0) is a high-performance operator panel belonging to the SIMATIC HMI Multi Panel family. It features a 12-inch TFT display and is designed for demanding visualization and control tasks in industrial automation environments. The MP 377 is part of Siemens' SIMATIC HMI portfolio and operates under the Windows CE operating system, providing a robust and flexible platform for machine-level HMI applications.

The 6AV6644-5AB10-0BS0 variant is equipped with a resistive touch screen and supports a display resolution of 800 x 600 pixels (SVGA) with 64,000 colors. It provides multiple communication interfaces including PROFIBUS DP, PROFINET (Ethernet), MPI, and USB ports, enabling seamless integration into a wide range of automation architectures. The panel includes 12 MB of user memory for project data and supports WinCC flexible as its configuration software. It operates on a 24 V DC supply and carries protection ratings suitable for front-panel mounting in control cabinets.

The MP 377 is widely deployed in machine building, automotive manufacturing, food and beverage processing, and chemical industries where a reliable and versatile HMI solution is required. Its multi-protocol communication capability makes it suitable for use with SIMATIC S7 PLCs as well as third-party controllers. The large display size and touch interface allow operators to monitor complex process visualizations and interact with machine controls efficiently.

Common Error Codes & System Events

Event ID: 10000: Project transfer error — communication between the configuration PC and the panel could not be established during project download.
Check the transfer cable and interface settings. Ensure the correct transfer channel (Ethernet, USB, or MPI/PROFIBUS) is selected on both the panel and WinCC flexible. Verify IP address or MPI address configuration.
Event ID: 10001: Project load error — the project file on the panel is corrupt or incompatible with the current runtime version.
Re-transfer the project from WinCC flexible. Ensure the WinCC flexible version used for configuration matches the runtime version installed on the panel.
Event ID: 20000: PLC connection lost — the HMI panel has lost communication with the configured PLC or controller.
Check the PROFIBUS, MPI, or Ethernet cable connections. Verify PLC address settings and ensure the PLC is in RUN mode. Check for network faults or address conflicts.
Event ID: 20001: Tag read error — the panel cannot read a configured tag from the connected 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: 40000: System memory low — available runtime memory on the panel is insufficient to execute the current project.
Reduce the number of active screens or objects in the project. Archive log data and clear the panel memory. Consider optimizing the project in WinCC flexible.
Event ID: 50000: Backup battery low — the internal backup battery voltage is below the threshold required to retain data during power loss.
Replace the internal backup battery as soon as possible. Refer to the MP 377 operating instructions for the correct battery type and replacement procedure.
Event ID: 60000: Screensaver active — the display backlight has been switched off due to inactivity timeout.
This is a normal system event. Touch the screen or press a key to reactivate the display. Adjust the screensaver timeout in the panel system settings if required.
Event ID: 70000: Illegal user operation — an operator attempted to access a function or screen protected by a configured access level.
Log in with a user account that has sufficient privileges for the requested function. Review and update user administration settings in the WinCC flexible project if access rights need adjustment.

Frequently Asked Questions

What configuration software is required for the MP 377 (6AV6644-5AB10-0BS0)?

The MP 377 is configured using Siemens WinCC flexible 2008 or later. Projects created in WinCC flexible can be transferred to the panel via Ethernet, USB, or MPI/PROFIBUS connection.

Which PLCs are compatible with the Siemens MP 377 panel?

The MP 377 natively supports SIMATIC S7-200, S7-300, S7-400, and S7-1200 PLCs via MPI, PROFIBUS DP, or PROFINET interfaces. It also supports third-party controllers through configurable communication drivers available in WinCC flexible.

What is the input voltage requirement for the 6AV6644-5AB10-0BS0?

The panel requires a 24 V DC power supply. The permissible voltage range is typically 19.2 V DC to 28.8 V DC, and the maximum power consumption is approximately 30 W.

Does the MP 377 support PROFINET communication?

Yes, the 6AV6644-5AB10-0BS0 includes an integrated PROFINET (Ethernet) interface supporting 10/100 Mbit/s, in addition to MPI and PROFIBUS DP interfaces.

What is the IP protection rating of the MP 377 front panel?

The front panel of the MP 377 achieves IP65 protection when correctly installed in a panel cutout with the supplied seal, making it suitable for environments where dust and water jets may be present.

Troubleshooting

Display remains blank after power on

Check that 24 V DC is present at the power supply terminals. Measure voltage at the panel connector and verify polarity. Check if the power LED on the rear of the panel is illuminated.

If voltage is correct but the display remains blank, the backlight inverter or the display itself may have failed. Try performing a hard reset by cycling power. If the issue persists, the panel may require backlight replacement or internal repair.

Touch screen does not respond or responds inaccurately

Determine whether the issue is a complete lack of response or positional inaccuracy. Check for physical damage or contamination on the touch surface. Attempt to access the panel via the system menu using an external USB mouse.

Perform a touch screen recalibration from the Windows CE control panel or the SIMATIC HMI startup center. If the touch screen is unresponsive after calibration, the resistive touch overlay may be damaged and require replacement.

Panel fails to establish communication with the PLC

Verify the communication cable connections on both the panel and PLC sides. Check the configured MPI address, PROFIBUS address, or IP address in the WinCC flexible project against the actual PLC settings. Use the panel's diagnostic tools to ping the PLC or check bus status.

Correct any address mismatches in the project configuration and re-transfer the project. Replace the communication cable if damaged. Ensure the PLC is powered and in RUN mode. Check for bus termination resistors on PROFIBUS networks.

Project transfer from WinCC flexible fails

Check the transfer channel selected on the panel (Control Panel > Transfer). Verify that the panel is in Transfer mode. Confirm the PC and panel are on the same network subnet if using Ethernet, or that the MPI/PROFIBUS adapter is correctly installed and configured.

Switch the panel to Transfer mode manually via the Start Center. Ensure firewall software on the PC is not blocking WinCC flexible communication. Try an alternative transfer channel (e.g., USB instead of Ethernet) to isolate the fault.

Panel reboots unexpectedly or freezes during operation

Check the supply voltage for stability and ripple. Review the system event log on the panel for recorded fault events prior to the reboot. Determine whether the issue is project-related by loading a minimal test project.

Ensure the 24 V DC power supply is adequately rated and free from voltage dips. Optimize the WinCC flexible project to reduce memory and CPU load. If reboots persist with a minimal project, the panel hardware may require servicing or the operating system may need to be restored using the Siemens recovery image.
