Common Error Codes & System Events

Event ID: 10000: Communication error between the HMI panel and the connected PLC or controller. The configured connection cannot be established.
Check PROFIBUS or Ethernet cable connections and termination resistors. Verify the PLC address settings match the HMI project configuration. Restart both the PLC and the HMI panel.
Event ID: 10001: Connection to the PLC was interrupted during runtime operation.
Inspect physical communication cables for damage. Verify network settings and PLC program is running. Re-establish the connection via the HMI Start Center if necessary.
Event ID: 20000: Tag read error. The HMI panel cannot read a configured tag from the PLC.
Verify the tag address in WinCC flexible matches the actual PLC data block or memory area. Check that the PLC program contains the referenced data area.
Event ID: 20001: Tag write error. The HMI panel cannot write a value to the configured PLC tag.
Check write permissions for the tag in the PLC program. Ensure the data block is not write-protected and the tag address is correct in the HMI project.
Event ID: 40000: Project download error. Transfer of the HMI project from the engineering PC to the panel failed.
Verify the transfer cable or Ethernet connection between the PC and panel. Ensure the panel is in Transfer mode via the Start Center. Check that WinCC flexible version is compatible with the panel firmware.
Event ID: 50000: System memory low. Available memory on the panel is insufficient to load or run the project.
Reduce project size by optimizing graphics and removing unused elements. Clear the panel memory via the Start Center before reloading the project.
Event ID: 70000: Firmware update error. The firmware update process was interrupted or failed.
Restart the panel and attempt the firmware update again using the correct firmware version for the MP 377 from the Siemens support portal. Ensure stable power supply during the update.
Event ID: 110000: Recipe data error. A recipe record could not be read from or written to the configured storage location.
Check the recipe configuration in WinCC flexible. Verify the storage medium (internal memory or external USB/CF card) is available and not full or corrupted.

Frequently Asked Questions

What engineering software is required to program the MP 377 (6AV6146-3LP40-0KC2)?

The MP 377 is programmed using Siemens WinCC flexible 2008 or later. It is not compatible with TIA Portal WinCC Advanced without a migration step.

Which PLCs are compatible with the SIMATIC MP 377?

The MP 377 is compatible with Siemens SIMATIC S7-200, S7-300, S7-400, and S7-1200 PLCs via PROFIBUS DP or Ethernet/PROFINET. Third-party PLCs can also be connected via the serial RS-422/RS-485 interface using supported drivers.

What communication interfaces does the 6AV6146-3LP40-0KC2 support?

This panel supports PROFIBUS DP (up to 12 Mbit/s), PROFINET/Industrial Ethernet via RJ45, two USB ports (host and device), and a serial RS-422/RS-485 interface.

Is the front panel of the MP 377 rated for washdown or dusty environments?

Yes, the front face of the MP 377 is rated IP65, providing full protection against dust ingress and protection against water jets, making it suitable for use in washdown and dusty industrial environments.

Can the MP 377 display be used with a keyboard or mouse?

Yes, the MP 377 includes USB host ports that support the connection of an external USB keyboard and USB mouse for operator input in addition to the touchscreen.

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 19.2–28.8 V DC tolerance range. Inspect the internal fuse if accessible.

Correct any wiring errors or supply voltage issues. If the supply is confirmed good and the display remains blank, the backlight inverter or internal power supply board may require replacement or professional repair.

Touchscreen does not respond or registers incorrect touch positions

Check whether the touchscreen is physically damaged or contaminated. Attempt a touchscreen recalibration via the Windows CE Control Panel accessible through the Start Center.

Clean the touchscreen surface with a soft cloth. Perform a touchscreen calibration in the Control Panel. If calibration does not resolve the issue, the resistive touch layer may be worn or damaged and the panel may require a display assembly replacement.

HMI project fails to transfer from engineering PC to the panel

Verify the panel is set to Transfer mode via the Start Center. Check the Ethernet or USB transfer cable connection. Confirm the IP address settings on both the PC and the panel are on the same subnet.

Set the correct transfer channel in WinCC flexible project settings. Disable any PC firewall temporarily during transfer. Ensure the firmware version on the panel is compatible with the WinCC flexible version being used.

Panel repeatedly reboots or freezes during runtime

Check the supply voltage for stability and ripple. Inspect the project for memory overload or corrupted project data. Review system event logs accessible via the Start Center for specific event IDs.

Ensure the power supply is stable and adequately rated (minimum 2.5 A at 24 V DC). Reload the HMI project after clearing panel memory. If the issue persists, update the panel firmware to the latest version available from Siemens support.

Communication loss between the MP 377 and the PLC during operation

Check PROFIBUS cable termination and connector integrity. For Ethernet connections, verify switch/hub port status and cable condition. Confirm PLC is in RUN mode and the communication parameters match the HMI project configuration.

Replace damaged cables or connectors. Verify PROFIBUS termination resistors are enabled only at the two physical ends of the bus. Correct any mismatched baud rate or address settings in both the PLC and the WinCC flexible project.
