Common Error Codes & System Events

Event ID: 10000: Communication error between HMI panel and PLC. Connection to the configured controller cannot be established.
Check PROFIBUS or Ethernet cable connections and verify the PLC address settings in the HMI project configuration. Ensure the PLC is in RUN mode.
Event ID: 10001: Connection to PLC interrupted during operation. The HMI panel lost communication with the controller.
Inspect network cabling and connectors. Verify PLC is operational and check for address conflicts on the network.
Event ID: 40000: Project download error. The project could not be transferred to the HMI panel.
Check the transfer cable or network connection between the engineering PC and the panel. Ensure the panel is in Transfer mode and that WinCC flexible project settings match the panel type.
Event ID: 20000: Tag read/write error. A configured tag could not be read from or written to the PLC.
Verify the tag address in the HMI project matches the actual PLC memory address. Check PLC program for address availability.
Event ID: 50000: System memory low. Available memory on the HMI panel is insufficient for current operations.
Reduce the number of active alarms or logged data. Archive or delete old data logs and alarm logs from the panel storage.
Event ID: 70000: Backup battery low or missing. The internal buffer battery voltage is below the required threshold.
Replace the internal buffer battery with the correct Siemens replacement battery. Follow ESD precautions during replacement.
Event ID: 30000: Screen saver or display fault. The display has not received a valid signal or the backlight has failed.
Check the 24 V DC power supply voltage at the panel connector. If the backlight has failed, the panel display unit may require replacement or repair.

Frequently Asked Questions

What PLC systems is the SIMATIC MP 377 compatible with?

The MP 377 is compatible with Siemens SIMATIC S7-300, S7-400, S7-1200, and S7-1500 PLCs via MPI, PROFIBUS DP, or PROFINET interfaces. It can also communicate with third-party controllers using OPC or other supported drivers in WinCC flexible.

What engineering software is required to program the MP 377?

The MP 377 is programmed using Siemens SIMATIC WinCC flexible 2008 or later. Projects are transferred to the panel via Ethernet, USB, or a direct MPI/PROFIBUS connection.

What is the supply voltage for the 6AV6146-1QQ05-0KY3?

The panel requires a 24 V DC power supply, typically with a tolerance of 19.2 V DC to 28.8 V DC.

Does the MP 377 support data logging and alarm archiving?

Yes, the MP 377 supports data logging and alarm archiving to internal flash memory or external USB storage devices, depending on project configuration.

What is the front panel protection rating of the MP 377?

The front panel of the MP 377 carries an IP65 protection rating, making it suitable for installation in environments where dust and water jets may be present.

Troubleshooting

Display remains blank after power on

Measure the 24 V DC supply voltage at the panel power connector. Check if the power LED is illuminated. Determine whether the panel is booting (listen for startup sounds or check for backlight glow).

Verify and correct the 24 V DC supply. If the supply is correct but the display remains blank, the backlight inverter or display unit may have failed and the panel should be sent for repair or the display assembly replaced.

HMI panel cannot establish communication with the PLC

Check the physical cable connections on the PROFIBUS, MPI, or Ethernet port. Verify the PLC address and network settings in the WinCC flexible project match the actual PLC configuration.

Replace or reseat the communication cable. Correct any address mismatches in the project settings and re-download the project to the panel. Ensure the PLC is in RUN mode and the network is free of address conflicts.

Touchscreen does not respond or is inaccurate

Check if the touch function is enabled in the panel settings. Attempt to recalibrate the touchscreen through the Windows CE control panel or the SIMATIC HMI panel startup menu.

Perform a touchscreen recalibration via the panel's Start Center or Control Panel. If the touchscreen remains unresponsive after calibration, the touch overlay may be damaged and require replacement.

Project transfer from engineering PC fails

Verify that the panel is set to Transfer mode. Check the Ethernet or USB connection between the PC and the panel. Confirm that the WinCC flexible project is configured for the correct panel type and firmware version.

Set the panel to Transfer mode via the Start Center. Ensure the correct IP address or COM port is configured in WinCC flexible. Update the panel firmware if there is a version mismatch between the project and the panel.

Panel reboots unexpectedly or freezes during operation

Check the 24 V DC supply for voltage dips or instability using a multimeter or oscilloscope. Review the alarm and event logs on the panel for system error events recorded before the reboot.

Stabilize the power supply by using a dedicated 24 V DC source with adequate current capacity. If the issue persists, check for project configuration errors such as excessive tag polling rates, and consider updating the panel firmware to the latest version.
