This panel features a 15-inch widescreen TFT display and is part of the MP 377 series, which represents Siemens' advanced panel line for demanding industrial visualization tasks. It operates as a standalone HMI device capable of running WinCC flexible runtime environments.

The MP 377 15" Touch (6AV6146-3LP40-0KB2) is equipped with a resistive touchscreen and delivers a display resolution of 1024 x 768 pixels with 64,000 colors. It features a 32 MB user memory for project data and supports multiple communication interfaces including PROFIBUS DP, PROFINET/Ethernet (RJ45), USB, and a serial RS-422/RS-485 interface. The panel runs on a Windows CE 5.0 operating system and includes an integrated CF card slot for additional storage. It operates on a 24 V DC supply and is rated to IP65 on the front face.

The MP 377 is widely deployed in machine building, automotive manufacturing, process industries, and water/wastewater treatment plants where large-format visualization and robust operator control are required. Its multi-protocol communication capability makes it suitable for integration into both SIMATIC S7 PLC environments and third-party controller systems. The panel's industrial-grade construction and broad connectivity options make it a reliable choice for complex SCADA and HMI applications.

Common Error Codes & 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 cable connections and termination resistors. Verify PLC is powered and running. Confirm communication parameters (address, baud rate) match on both devices.
Event ID: 10001: Tag read error. The HMI panel cannot read the value of a configured tag from the PLC.
Verify the tag address exists in the PLC program. Check that the data block or memory area referenced is present and accessible. Confirm communication link is active.
Event ID: 10002: Tag write error. The HMI panel cannot write a value to the configured PLC tag.
Check that the target PLC address is not write-protected. Verify the tag configuration in WinCC flexible. Ensure the PLC is in RUN mode and accepting write requests.
Event ID: 20000: Project transfer error. A project download to the panel has failed or been interrupted.
Check the transfer cable or network connection. Ensure WinCC flexible runtime is stopped before transfer. Verify sufficient free memory on the panel and retry the transfer.
Event ID: 40000: System memory low. Available runtime memory on the panel is critically low.
Reduce the number of active screens or logged data. Delete unnecessary files from the CF card. Consider reducing project complexity or increasing CF card storage.
Event ID: 50000: CF card not found or removed during operation. The CompactFlash card is missing or has been ejected while the system is running.
Re-insert the CF card and restart the panel. Ensure the CF card is properly seated. Do not remove the CF card during panel operation.
Event ID: 70000: Backup/restore error. A backup or restore operation of the panel project has failed.
Check that the CF card has sufficient free space. Verify the CF card is not write-protected. Retry the backup/restore operation using ProSave or WinCC flexible.

Frequently Asked Questions

What software is used to configure and program the MP 377 panel?

The MP 377 (6AV6146-3LP40-0KB2) is configured using Siemens WinCC flexible 2008 or later. Projects are transferred to the panel via Ethernet, USB, or serial connection using the ProSave tool or directly from WinCC flexible.

Which PLC systems are compatible with the MP 377?

The MP 377 supports communication with Siemens SIMATIC S7-200, S7-300, S7-400, and S7-1200 PLCs via PROFIBUS DP or PROFINET/Ethernet. It also supports third-party controllers through serial drivers and OPC connections.

What is the supply voltage for the 6AV6146-3LP40-0KB2?

The panel requires a 24 V DC power supply, typically in the range of 19.2 V DC to 28.8 V DC, connected via the rear terminal block.

Can the MP 377 be used as a PROFIBUS master or slave?

The MP 377 operates as a PROFIBUS DP slave for communication with a SIMATIC PLC acting as the DP master. It does not function as a PROFIBUS DP master.

What is the front panel protection rating of the 6AV6146-3LP40-0KB2?

The front face of the MP 377 is rated IP65, making it suitable for panel-mount installations where protection against dust and water jets is required. The rear of the unit is rated IP20.

Troubleshooting

Display remains blank after power on

Measure the 24 V DC supply voltage at the rear power terminal. Check that the voltage is within the 19.2–28.8 V DC range. Inspect the internal fuse and power connector for damage.

Correct the supply voltage if out of range. Replace the internal fuse if blown. If the backlight has failed, the display panel or inverter board may require replacement.

Touchscreen does not respond or registers incorrect touch positions

Check whether the touchscreen is physically damaged or contaminated. Attempt to recalibrate the touch input via the panel's Start Center or Control Panel settings in Windows CE.

Clean the touchscreen surface with a soft, dry cloth. Perform a touchscreen recalibration from the Start Center. If calibration fails repeatedly, the resistive touch layer may be worn and the display assembly should be replaced.

Panel fails to communicate with the PLC after project download

Verify the IP address or PROFIBUS address configured in the WinCC flexible project matches the panel's actual network settings. Check physical cable connections and switch/hub status.

Correct the communication parameters in the project and re-download. Ensure the Ethernet cable is connected to the correct port and that the network switch is operational. Test with a direct cable connection to isolate network issues.

Panel reboots repeatedly or freezes during operation

Check for overheating by verifying the ambient temperature is within the 0–50 °C operating range. Inspect the CF card for errors and check available memory. Review the project for script errors or memory leaks.

Improve ventilation around the panel. Replace a faulty or full CF card. Simplify the project if memory usage is excessive. Update the panel firmware to the latest version using ProSave.

Project transfer fails or is rejected by the panel

Confirm that the WinCC flexible version used to create the project is compatible with the panel's firmware version. Check that the transfer mode is enabled in the panel's Start Center and that the correct transfer channel is selected.

Enable transfer mode on the panel via the Start Center before initiating the download. Match the WinCC flexible project version to the panel firmware. Update panel firmware via ProSave if a version mismatch is confirmed.
