This panel features a 15-inch TFT display and runs on the Windows CE operating system, making it suitable for complex process visualization applications. It is part of Siemens' SIMATIC HMI MP 377 series, which bridges the gap between standard operator panels and full PC-based systems.
The MP 377 15" (6AV6146-1LP01-2KB1) is equipped with a resistive touchscreen and an integrated membrane keyboard, offering flexible operator input options. It supports multiple communication interfaces including PROFIBUS DP and Ethernet (PROFINET), enabling seamless integration into modern and legacy automation networks. The panel provides 12 MB of user memory for project data and is powered by a 24 V DC supply. It supports WinCC flexible runtime software and is compatible with the SIMATIC S7, S5, and third-party PLC families via configurable communication drivers.
The MP 377 is widely deployed in the manufacturing, automotive, food and beverage, chemical, and water treatment industries. Its combination of a large display, robust construction, and broad communication compatibility makes it well suited for machine-level HMI applications where operators require clear process overviews and reliable control interfaces. The panel is typically mounted in control cabinet doors or operator stations in environments with moderate to high demands on display size and system integration.

Common Error Codes and System Events
- Event ID: 10000
- Communication error between HMI panel and PLC. The configured connection to the controller cannot be established or has been lost.
Check PROFIBUS or Ethernet cabling and connector integrity. Verify PLC address settings match the HMI project configuration. Confirm the PLC is in RUN mode. - Event ID: 10001
- Connection timeout to the configured PLC. The HMI did not receive a response within the expected time window.
Check network or fieldbus cable connections. Verify baud rate and station address settings on both HMI and PLC. Restart both devices if the issue persists. - Event ID: 20000
- Tag read error. The HMI was unable to read the value of a configured process tag from the PLC.
Verify the tag address in the WinCC flexible project matches the actual PLC data block or memory area. Check PLC program for correct data availability. - Event ID: 20001
- Tag write error. A write operation to a PLC tag failed.
Check that the target PLC memory area is not write-protected. Verify the tag address configuration in the HMI project. Ensure the PLC is in a state that accepts write commands. - Event ID: 40000
- Project loading error. The HMI runtime was unable to load the configured project file from memory.
Re-transfer the project from the engineering PC using WinCC flexible. Check available user memory and ensure the project file is not corrupted. - Event ID: 50000
- System memory low. Available runtime memory on the HMI panel is critically low.
Reduce the number of active screens or logged data. Restart the panel to free memory. Consider optimizing the project to reduce memory usage. - Event ID: 70000
- Backup battery low or missing. The internal buffer battery voltage is below the required threshold.
Replace the internal backup battery with the correct Siemens replacement part. Refer to the MP 377 operating instructions for battery replacement procedure. - Event ID: 110000
- Recipe data error. An error occurred during reading or writing of recipe data records.
Check the recipe configuration in WinCC flexible. Verify that the target memory location has sufficient space and that the recipe structure matches the PLC data layout.
Frequently Asked Questions
What software is used to configure and program the MP 377 (6AV6146-1LP01-2KB1)?
The MP 377 is configured using Siemens WinCC flexible 2008 or later. Projects are created on an engineering PC and transferred to the panel via Ethernet, USB, or a memory card.
Which PLC families are compatible with the MP 377?
The MP 377 supports communication with Siemens SIMATIC S7-300, S7-400, S7-200, S5, and WinAC controllers via PROFIBUS DP or PROFINET. It also supports third-party PLCs through configurable serial and Ethernet drivers.
What is the input voltage requirement for the 6AV6146-1LP01-2KB1?
The panel requires a 24 V DC power supply. The permissible voltage range is typically 19.2 V DC to 28.8 V DC.
Does the MP 377 support data logging and alarm archiving?
Yes, the MP 377 supports data logging, alarm logging, and recipe management as part of the WinCC flexible runtime. Data can be stored internally or on an external USB storage device or memory card.
What is the front panel protection rating of the MP 377?
The front panel of the MP 377 achieves IP65 protection, making it resistant to dust ingress and low-pressure water jets, suitable for installation in control cabinet doors in industrial environments.
Troubleshooting
Display remains blank after power is applied
Measure the 24 V DC supply voltage at the power connector on the rear of the panel. Check that the voltage is within the 19.2 V to 28.8 V DC range. Inspect the internal fuse if accessible.
Correct the supply voltage if out of range. Replace any blown fuse with the correct rating as specified in the MP 377 operating instructions. If the supply is correct and the display remains blank, the backlight inverter or display unit may require replacement.
HMI panel fails to establish communication with the PLC
Verify the PROFIBUS station address or Ethernet IP address configured in the HMI project matches the actual PLC settings. Check physical cable connections and inspect for damaged connectors or broken shielding.
Correct any address mismatches in the WinCC flexible project and re-transfer to the panel. Replace damaged cables or connectors. Ensure the PROFIBUS terminating resistors are correctly placed at both ends of the bus segment.
Touchscreen does not respond accurately to touch input
The resistive touchscreen may require recalibration, particularly after a project transfer or following physical impact. Access the Control Panel via the Windows CE Start menu to check calibration settings.
Run the touchscreen calibration utility from the Windows CE Control Panel. If calibration does not resolve the issue, inspect the touchscreen surface for damage or contamination and clean with a soft, dry cloth. A persistently unresponsive touchscreen may indicate hardware failure requiring panel repair.
Project transfer from engineering PC fails or is interrupted
Check the Ethernet or USB connection between the engineering PC and the HMI panel. Verify that the correct transfer channel is enabled on the panel under Start > Control Panel > Transfer. Confirm firewall or antivirus software on the PC is not blocking the WinCC flexible transfer tool.
Enable the correct transfer channel on the panel and ensure the IP address or USB connection is correctly configured in WinCC flexible. Disable interfering firewall rules temporarily during transfer. If using Ethernet, verify both devices are on the same subnet.
Panel reboots unexpectedly or freezes during operation
Check the 24 V DC supply for voltage dips or instability, which can cause unexpected resets. Review the alarm and event log on the panel for any system error events recorded prior to the reboot. Inspect the panel for signs of overheating.
Stabilize the power supply using a dedicated 24 V DC UPS or power conditioner. Ensure the panel's ventilation slots are not obstructed and ambient temperature is within the 0 °C to 50 °C operating range. If the issue persists, re-transfer the project and consider a factory reset followed by a clean project load.
