The MP 377 15" Touch is equipped with a resistive touchscreen interface and delivers a display resolution of 1024 x 768 pixels with 64,000 colors. It supports multiple communication interfaces including PROFIBUS DP, PROFINET IO (Ethernet), MPI, and USB ports, enabling seamless integration into a wide range of automation architectures. The panel is powered by a 24 V DC supply and offers 12 MB of user memory for project data, along with a CompactFlash card slot for extended storage. It is rated IP65 on the front face, ensuring protection against dust and water ingress in industrial environments.
The SIMATIC MP 377 is widely deployed in machine building, automotive manufacturing, food and beverage processing, and chemical industry applications where a large, high-resolution display with robust connectivity is required. Its compatibility with Siemens SIMATIC S7 PLCs and WinCC flexible engineering software makes it a natural choice for Siemens-based automation systems. The panel's rugged construction and broad communication support make it suitable for both standalone machine HMI and networked plant visualization tasks.

Common Error Codes & System Events
- Event ID: 1000000
- Project transfer error — communication between the engineering PC and the panel could not be established during download.
Check the transfer cable and interface settings. Ensure the correct transfer channel (Ethernet, USB, or MPI) is selected on both the panel and WinCC flexible. Verify IP address or MPI address configuration. - Event ID: 1000002
- Project data corrupted or incompatible — the loaded project cannot be opened or executed by the panel runtime.
Re-transfer the project from WinCC flexible. Ensure the WinCC flexible version matches the panel firmware version. Perform a panel reset if necessary. - Event ID: 1000003
- No project found on the panel — the panel starts in transfer mode because no valid project is stored.
Transfer a valid project to the panel using WinCC flexible via USB, Ethernet, or MPI/PROFIBUS connection. - Event ID: 1000010
- PLC connection lost — the HMI panel has lost communication with the configured SIMATIC PLC.
Check PROFIBUS/PROFINET/MPI cabling and termination resistors. Verify PLC address settings match the HMI project configuration. Check PLC operating state. - Event ID: 1000020
- Tag read/write error — a configured variable (tag) could not be read from or written to 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 conflicts. - Event ID: 1000050
- System memory low — the panel runtime is reporting insufficient memory to execute the current project.
Reduce the project size by optimizing graphics and scripts. Clear unused data from the CompactFlash card. Consider splitting the project across multiple panels if necessary. - Event ID: 1000070
- Firmware update failed — an error occurred during the panel firmware update process.
Restart the firmware update procedure using ProSave or WinCC flexible. Ensure the correct firmware version for the MP 377 15" is used and that the power supply is stable during the update.
Frequently Asked Questions
What PLC systems is the SIMATIC MP 377 compatible with?
The MP 377 is compatible with Siemens SIMATIC S7-200, S7-300, S7-400, and S7-1200 PLCs via MPI, PROFIBUS DP, or PROFINET IO. It can also communicate with third-party PLCs using supported drivers configured in WinCC flexible.
What engineering software is required to program this panel?
The MP 377 is programmed using Siemens WinCC flexible 2008 or later. Projects are created on a PC and transferred to the panel via USB, Ethernet, or MPI/PROFIBUS connection.
What is the display size and touch technology used in the 6AV6146-4PP40-1KY3?
This panel features a 15-inch TFT LCD display with a resolution of 1024 x 768 pixels and uses a resistive touchscreen for operator input.
Can the MP 377 be used in environments with dust and moisture?
Yes, the front face of the MP 377 is rated IP65, making it suitable for environments with dust and water spray. The rear of the unit is rated IP20 and should be protected accordingly.
Does the 6AV6146-4PP40-1KY3 support data logging or recipe management?
Yes, the MP 377 supports data logging and recipe management functions through WinCC flexible. Data can be stored on the internal memory or on a CompactFlash card inserted into the expansion slot.
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. Inspect the internal fuse if accessible. Verify the power supply can deliver sufficient current (at least 2 A).
Ensure a stable 24 V DC supply with adequate current capacity. If the supply is confirmed good and the display remains blank, the internal backlight or power supply board may be faulty and require replacement or professional repair.
Panel starts in transfer mode and no project loads
This occurs when no valid project is stored on the panel, or the project has been deleted. The panel defaults to transfer mode on startup when no runtime project is found.
Connect the engineering PC via USB or Ethernet and transfer a valid WinCC flexible project to the panel. Ensure the project is compiled without errors before transfer.
Communication fault with SIMATIC PLC — connection repeatedly drops
Check the PROFIBUS or PROFINET cable connections and verify termination resistors are correctly placed at both ends of the PROFIBUS segment. For PROFINET, check Ethernet switch and cable integrity. Verify the PLC address in the HMI project matches the actual PLC configuration.
Replace damaged cables, correct termination, and ensure address settings are consistent between the HMI project and the PLC hardware configuration. Update the PLC hardware configuration in STEP 7 or TIA Portal if addresses were changed.
Touchscreen does not respond accurately or is misaligned
The resistive touchscreen may require recalibration, especially after a firmware update or if the panel has been exposed to temperature extremes. Access the calibration utility through the panel's Start Center or Control Panel under Windows CE.
Run the touchscreen calibration routine from the panel's Start Center (Settings > Calibrate Touch Screen). Follow the on-screen prompts to recalibrate. If the touchscreen remains unresponsive, the touch overlay may be damaged and require replacement.
Panel firmware update fails or panel becomes unresponsive after update
A failed firmware update can leave the panel in an inconsistent state. This may be caused by a power interruption during the update, an incorrect firmware file, or a communication error during the transfer.
Use the Siemens ProSave tool to perform a recovery firmware update via USB or Ethernet. Ensure the correct firmware version for the MP 377 15" (6AV6146-4PP40-1KY3) is used. Maintain stable power throughout the update process.
