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 PROFINET cable connections and termination resistors. Verify PLC is powered and running. Confirm communication parameters (station address, baud rate) match on both devices.
Event ID: 10001: Connection timeout to the PLC. The HMI did not receive a response from the controller within the configured timeout period.
Check network cabling and connectors. Verify PLC program is running and the communication driver is correctly configured. Increase the timeout value in the HMI project settings if necessary.
Event ID: 40000: Tag read error. A configured tag could not be read from the PLC, possibly due to an incorrect address or data type mismatch.
Verify the tag address and data type in the HMI project match the actual PLC data block or memory area. Check that the PLC program has not been modified without updating the HMI project.
Event ID: 40001: Tag write error. A value could not be written to the PLC tag, possibly due to write protection or an address conflict.
Check that the target PLC memory area is not write-protected. Verify the tag address and data type configuration in WinCC flexible or TIA Portal WinCC.
Event ID: 20000: Project download error. The project could not be transferred to the HMI panel, possibly due to a network or USB communication issue.
Check the transfer cable or network connection between the engineering PC and the HMI panel. Ensure the panel is in Transfer mode and that the correct transfer channel is selected in the project settings.
Event ID: 50000: System memory low. Available RAM or flash memory on the HMI panel is critically low, which may cause instability or project loading failures.
Reduce the project size by optimizing graphics and scripts. Delete unnecessary files from the panel's flash memory. Consider archiving or removing log files stored on the device.
Event ID: 70010: Backup battery low or missing. The internal backup battery voltage has dropped below the minimum threshold, risking loss of time/date settings and buffered data.
Replace the internal backup battery with the correct Siemens-specified replacement. Refer to the MP 377 operating instructions for battery replacement procedure.

Frequently Asked Questions

What engineering software is compatible with the SIMATIC MP 377 (6AV6146-3LP41-0KC2)?

The MP 377 is compatible with Siemens WinCC flexible 2008 SP3 or later, as well as SIMATIC WinCC in the TIA Portal (with appropriate migration). WinCC flexible is the primary engineering tool for creating and transferring HMI projects to this panel.

What communication protocols does the 6AV6146-3LP41-0KC2 support?

This panel supports PROFIBUS DP and PROFINET (Industrial Ethernet) for PLC communication, as well as RS-422/RS-485 serial communication. It also includes two USB ports for project transfer and peripheral devices.

What is the display size and touch technology used on this panel?

The 6AV6146-3LP41-0KC2 features a 15-inch TFT LCD display with a resolution of 1024 x 768 pixels and uses resistive touchscreen technology.

What is the supply voltage required for the MP 377 panel?

The panel requires a 24 V DC power supply. The permissible voltage range is typically 19.2 V DC to 28.8 V DC (24 V DC -20% / +20%).

Is the front of the MP 377 panel protected against dust and water ingress?

Yes, the front panel of the MP 377 meets IP65 protection rating, making it resistant to dust and low-pressure water jets. The rear of the unit is rated IP20.

Troubleshooting

Display remains blank after power is applied

Check that 24 V DC is present at the power supply terminals. Measure voltage at the panel's power connector. Inspect internal fuses if accessible. Verify the power supply unit can deliver sufficient current.

Ensure the power supply provides stable 24 V DC within the permissible range (19.2–28.8 V DC). Replace any blown fuses. If the backlight has failed, the panel may require backlight or display assembly replacement.

HMI panel cannot establish communication with the PLC

Verify the PROFIBUS address or IP address settings on both the HMI and PLC. Check cable integrity and connector seating. Use diagnostic tools in WinCC flexible or TIA Portal to check connection status.

Correct any mismatched communication parameters (address, baud rate, subnet). Replace damaged cables or connectors. Ensure PROFIBUS termination resistors are correctly placed at both ends of the bus segment.

Touchscreen does not respond or responds inaccurately

Check for physical damage or contamination on the touchscreen surface. Attempt to recalibrate the touchscreen via the panel's Control Panel settings in Windows CE.

Clean the touchscreen surface with a soft, dry cloth. Perform a touchscreen calibration from the Windows CE Control Panel. If calibration does not resolve the issue, the touchscreen overlay may need replacement.

Project cannot be transferred from engineering PC to the panel

Verify the panel is set to Transfer mode (accessible from the Start Center on the panel). Check that the correct transfer channel (Ethernet or USB) is selected and that the PC and panel are on the same network subnet if using Ethernet.

Switch the panel to Transfer mode via the Start Center. Confirm firewall settings on the PC are not blocking the transfer. Use a direct USB connection as an alternative to network transfer if Ethernet communication is unreliable.

Panel displays 'No project' or loads an incorrect project after restart

Check the flash memory on the panel for available storage space. Verify the project was fully and successfully transferred without errors during the last download operation.

Re-transfer the project from the engineering PC using WinCC flexible, ensuring the transfer completes without errors. If the panel's flash memory is corrupted, perform a factory reset via the Start Center and re-transfer the project.
