Common Error Codes & System Events
- Event ID: 10000
- Connection to the PLC could not be established or was interrupted during runtime.
Check PROFIBUS or Ethernet cable connections and verify PLC address settings in the WinCC flexible project. Confirm the PLC is powered and in RUN mode. - Event ID: 10001
- Tag read error — the HMI panel cannot read a configured tag from the connected controller.
Verify the tag address in the WinCC flexible configuration matches the actual PLC data block or memory address. Check communication settings and PLC program. - Event ID: 10002
- Tag write error — the HMI panel failed to write a value to the configured controller tag.
Check that the target PLC address is writable and not write-protected. Verify communication link integrity and tag configuration in the project. - Event ID: 20000
- Project download failed or project data is corrupted on the panel.
Re-transfer the project from the engineering PC using WinCC flexible or TIA Portal. Ensure the project version is compatible with the panel firmware version. - Event ID: 40000
- System memory low — available runtime memory on the panel is insufficient.
Reduce the number of active screens or objects in the project. Archive log data to CompactFlash card and restart the panel to free memory. - Event ID: 50000
- Firmware update error — firmware transfer to the panel was interrupted or failed.
Restart the panel in transfer mode using the Control Panel boot options and re-initiate the firmware update from the ProSave tool or TIA Portal. - Event ID: 60000
- Screen saver or backlight timeout has been triggered; display has gone dark.
Touch the screen or press any key to reactivate the display. Adjust screen saver settings in the panel Control Panel if timeout is too short for the application. - Event ID: 70000
- Date and time synchronization error — panel clock could not be synchronized with the PLC or NTP server.
Check the time synchronization settings in the WinCC flexible project. Verify network connectivity if using NTP, or configure PLC-based time synchronization.
Frequently Asked Questions
Which engineering software is used to configure the SIMATIC MP 377?
The MP 377 is configured using Siemens WinCC flexible 2008 or later. It is also supported in the TIA Portal via WinCC (for migration and limited use cases), but WinCC flexible is the primary engineering tool for this panel generation.
What communication protocols does the 6AV6146-1LP00-1KB1 support?
The panel supports PROFIBUS DP, MPI, PROFINET via Ethernet (RJ45), RS-422/RS-485 serial communication, and USB 2.0. This allows direct connection to Siemens S7-300, S7-400, and S7-1200/1500 PLCs as well as third-party controllers.
Is the MP 377 15" Touch compatible with Siemens S7-300 and S7-400 PLCs?
Yes, the MP 377 supports direct communication with S7-300 and S7-400 PLCs via MPI, PROFIBUS DP, or PROFINET/Ethernet, making it a common pairing in existing Siemens automation installations.
What is the front protection rating of this panel?
The front panel of the 6AV6146-1LP00-1KB1 is rated IP65, making it protected against dust ingress and low-pressure water jets, suitable for installation in industrial control cabinet doors.
Can the MP 377 use a CompactFlash card for additional storage?
Yes, the MP 377 is equipped with a CompactFlash card slot that can be used for extended project storage, data logging, recipe management, and firmware updates.
Troubleshooting
Display remains blank after power is applied
Measure the 24 V DC supply voltage at the panel's power connector. Check that polarity is correct and voltage is within the 20.4–28.8 V DC tolerance range. Inspect the internal backlight fuse if accessible.
Correct any wiring or power supply issues. If supply voltage is confirmed correct but display remains blank, the backlight inverter or LCD panel may be faulty and the unit should be sent for repair or the backlight replaced.
Touchscreen does not respond or registers incorrect touch positions
Check whether the touch issue is consistent across the entire screen or localized to one area. Attempt a touchscreen recalibration via the Windows CE Control Panel under the Siemens Start menu.
Recalibrate the touchscreen using the built-in calibration tool in the Control Panel. If calibration does not resolve the issue, the resistive touch overlay may be damaged or worn and requires replacement.
Panel cannot establish communication with the PLC
Verify the communication cable type and wiring (MPI, PROFIBUS, or Ethernet). Check the PLC address and baud rate settings in the WinCC flexible project match the physical PLC configuration. Use Siemens diagnostic tools to ping the PLC over Ethernet if applicable.
Correct any address or baud rate mismatches in the project configuration. Replace faulty communication cables. If using PROFIBUS, check bus termination resistors at both ends of the network segment.
Panel freezes or restarts unexpectedly during operation
Check the 24 V DC supply for voltage dips or ripple using an oscilloscope or multimeter. Review the Windows CE event log for software exceptions. Check if the CompactFlash card is properly seated and not corrupted.
Stabilize the power supply and ensure it is adequately rated for the panel load. Reformat or replace the CompactFlash card if corrupted. If the issue persists, perform a firmware reinstallation using ProSave.
Project transfer from engineering PC fails or times out
Verify the transfer cable or Ethernet connection between the PC and panel. Ensure the panel is set to Transfer mode via the Control Panel or by holding the appropriate key during boot. Check that the WinCC flexible version matches the project version.
Switch the panel to Transfer mode manually and retry the download. Disable any firewall or antivirus software on the engineering PC that may block the transfer. If using Ethernet, ensure both devices are on the same subnet.
