Common Error Codes & System Events

Event ID: 10000: Configuration error detected during startup; the project file may be corrupted or incompatible with the panel firmware version.
Reload the WinCC flexible project to the panel. Verify that the firmware version on the panel matches the version used during project compilation.
Event ID: 10001: Communication connection to PLC lost or could not be established.
Check physical cable connections on PROFIBUS or PROFINET interface. Verify PLC address settings and network configuration in the WinCC flexible project.
Event ID: 20000: Internal system error; the runtime application has encountered an unhandled exception.
Restart the panel. If the error persists, perform a factory reset and reload the project. Check for firmware updates from Siemens.
Event ID: 40000: Tag read/write error; a configured tag could not be read from or written to the connected controller.
Verify the tag address in the WinCC flexible project matches the actual PLC data block or memory address. Check PLC program for address conflicts.
Event ID: 50000: Recipe data error; recipe records could not be read from or written to the configured storage location.
Check that the CompactFlash card is properly inserted and has sufficient free space. Verify recipe configuration in WinCC flexible.
Event ID: 70000: Alarm buffer overflow; the number of pending alarms has exceeded the configured buffer limit.
Acknowledge and clear pending alarms. Increase the alarm buffer size in the WinCC flexible project configuration if overflow occurs frequently.
Event ID: 80000: Screen object rendering error; one or more display objects could not be rendered correctly.
Check the project for unsupported object types or display elements that exceed panel capabilities. Recompile and reload the project.

Frequently Asked Questions

What configuration software is required for the SIMATIC MP 377?

The MP 377 is configured using Siemens WinCC flexible 2008 or later. Projects created in WinCC flexible can be transferred to the panel via Ethernet, USB, or a data card.

Which communication protocols does the 6AV6146-1QQ01-0LY4 support?

This panel supports MPI, PROFIBUS DP, PROFINET IO, and standard Ethernet (TCP/IP). USB ports are also available for project transfer and peripheral devices.

Is the MP 377 compatible with SIMATIC S7-300 and S7-400 PLCs?

Yes, the MP 377 can communicate directly with SIMATIC S7-300 and S7-400 PLCs via MPI, PROFIBUS DP, or PROFINET IO, as well as with S7-1200 and S7-1500 via Ethernet.

What is the supply voltage for this panel?

The panel operates on 24 V DC with a maximum power consumption of approximately 60 W.

Can the MP 377 use external storage for project data and logging?

Yes, the panel is equipped with a CompactFlash card slot that can be used for extended project storage, data logging, recipe management, and alarm archiving.

Troubleshooting

Display remains blank after power on

Measure 24 V DC supply voltage at the power connector. Check that the supply current is sufficient for the panel's power consumption. Inspect the internal fuse if accessible.

Ensure the 24 V DC power supply is stable and rated for at least 60 W. Replace the power supply if voltage is absent or unstable. If power is confirmed correct, the internal power supply board may require replacement.

Panel does not communicate with the PLC

Check the physical connection on the PROFIBUS or PROFINET port. Verify the PLC address and network parameters configured in the WinCC flexible project match the actual PLC settings.

Replace or reseat the communication cable. Correct any address mismatches in the project configuration. Confirm the PLC is in RUN mode and that the network is free of address conflicts.

Touch screen does not respond or responds inaccurately

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

Perform a touch screen recalibration via Start > Settings > Control Panel > Touch. Clean the screen surface with a soft cloth. If calibration fails repeatedly, the touch screen overlay may need replacement.

Panel repeatedly restarts or crashes during runtime

Check for corrupted project files by reloading a known-good project. Verify that the CompactFlash card is properly seated and not corrupted. Monitor operating temperature to ensure it is within the 0 to 50 °C range.

Reload the WinCC flexible project from a verified backup. Replace the CompactFlash card if it is found to be faulty. Ensure adequate ventilation around the panel to prevent thermal shutdown.

Project transfer via Ethernet fails

Verify the IP address of the panel in the Control Panel network settings. Confirm the PC and panel are on the same subnet. Check that no firewall is blocking the WinCC flexible transfer port.

Set the correct IP address on the panel and ensure it matches the target address configured in WinCC flexible. Disable any firewall or antivirus software temporarily during transfer. Use USB as an alternative transfer method if Ethernet transfer continues to fail.
