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 interrupted.
Check PROFIBUS or PROFINET cable connections and termination resistors. Verify PLC is powered and running. Confirm station address and network settings match the project configuration. - Event ID: 10001
- Connection to PLC timed out. The HMI did not receive a response from the controller within the configured timeout period.
Check network or fieldbus cabling. Verify PLC program is running and the communication driver is correctly configured. Increase timeout value in WinCC flexible project settings if necessary. - Event ID: 20000
- Tag read error. The HMI panel was unable to read the value of a configured tag from the PLC.
Verify the tag address exists in the PLC program and the data block is not write-protected. Check communication connection status and confirm correct data type mapping. - Event ID: 40000
- Project download error. A fault occurred during transfer of the HMI project from the engineering PC to the panel.
Ensure the panel is in transfer mode. Check the Ethernet or USB transfer cable. Verify WinCC flexible version compatibility with the panel firmware version. - Event ID: 70010
- Internal system error on the HMI panel. An unexpected software exception has occurred within the runtime environment.
Restart the panel. If the error persists, reload the HMI project. Consider updating the panel firmware to the latest version via Siemens support. - Event ID: 110000
- CF card not found or not readable. The panel cannot access the inserted CompactFlash card.
Remove and reinsert the CF card. Verify the card is formatted correctly (FAT16/FAT32). Replace the CF card if it is not recognized after reinsertion. - Event ID: 50000
- Printer communication error. The panel cannot establish communication with the configured printer.
Check the printer connection cable and printer power status. Verify the correct printer driver is configured in the WinCC flexible project settings.
Frequently Asked Questions
What is the supply voltage for the Siemens 6AV6146-3LP41-0KB2?
The MP 377 15" Touch operates on a 24 V DC supply voltage. Ensure the power supply is within the permissible tolerance range as specified in the device manual.
Which engineering software is used to configure the MP 377?
The 6AV6146-3LP41-0KB2 is configured using Siemens WinCC flexible 2008. Projects created in WinCC flexible can be transferred to the panel via Ethernet, USB, or CF card.
What communication interfaces are available on this panel?
The panel provides PROFIBUS DP (RS-485), PROFINET via RJ45 Ethernet, one RS-422/RS-485 serial interface, and USB host and device ports for peripherals and project transfer.
Is the MP 377 compatible with Siemens S7-300 and S7-400 PLCs?
Yes, the MP 377 supports direct communication with Siemens S7-300 and S7-400 PLCs via PROFIBUS DP or PROFINET, using the integrated communication drivers in WinCC flexible.
What is the IP protection rating of the front panel?
The front panel of the 6AV6146-3LP41-0KB2 carries an IP65 protection rating, making it suitable for installation in environments with dust and water spray exposure.
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 for correct polarity. Inspect the internal fuse if accessible.
Ensure the 24 V DC supply is within tolerance and correctly wired. If the supply is correct and the display remains blank, the internal power supply board or backlight inverter may require replacement.
Touchscreen does not respond or registers incorrect touch positions
Check whether the touch input is consistently offset or completely unresponsive. Attempt a touchscreen recalibration from the Windows CE control panel or the Start Center menu.
Perform a touchscreen calibration via the panel's Start Center. If the touch remains unresponsive, inspect the touchscreen ribbon cable connection internally. A damaged resistive touch overlay may require replacement.
Panel fails to establish communication with the PLC
Verify the PROFIBUS address or IP address configured on the panel matches the project settings. Check the physical cable connections and bus termination. Use diagnostic tools in WinCC flexible to check connection status.
Correct any address mismatches in the WinCC flexible project or on the panel's network settings. Replace faulty cables or connectors. Ensure PROFIBUS termination resistors are correctly placed at both ends of the bus segment.
HMI project cannot be downloaded to the panel
Confirm the panel is in Transfer mode (accessible via the Start Center). Check the Ethernet or USB cable between the engineering PC and the panel. Verify firewall settings on the PC are not blocking the transfer.
Switch the panel to Transfer mode before initiating the download. Use a known-good cable and disable PC firewall temporarily during transfer. Ensure the WinCC flexible version matches the panel firmware; update firmware if necessary.
Panel reboots unexpectedly or freezes during operation
Check the 24 V DC supply for voltage dips or ripple using an oscilloscope or multimeter. Review the system event log on the panel for recorded event IDs prior to the reboot.
Stabilize the power supply and ensure adequate current capacity. If the issue persists, reload the HMI project to rule out project corruption. Update the panel firmware to the latest version available from Siemens support.
