Common Error Codes & System Events

Event ID: 1000000: System startup completed. The HMI device has booted and the runtime software has started successfully.
No action required. Informational event confirming normal startup.
Event ID: 1000002: Connection to PLC lost. The HMI panel cannot establish or has lost communication with the configured PLC.
Check PROFIBUS or PROFINET cabling and connectors. Verify PLC is powered and running. Confirm network address and communication settings in WinCC flexible project.
Event ID: 1000003: Connection to PLC established. Communication between the HMI panel and the PLC has been successfully restored.
No action required. Informational event confirming restored communication.
Event ID: 1000005: Tag read/write error. A configured tag could not be read from or written to the PLC.
Verify the tag address in the WinCC flexible project matches the actual PLC data block or memory area. Check PLC program for address conflicts.
Event ID: 1000010: Project transfer active. A project download from the engineering PC to the HMI device is in progress.
No action required during intentional transfer. If unexpected, check network security and ensure no unauthorized access to the panel.
Event ID: 1000070: Illegal system activity. An operation was attempted that is not permitted in the current operating mode.
Review user authorization levels in the WinCC flexible project. Ensure the correct user group permissions are assigned for the attempted operation.
Event ID: 1000071: Data record transfer error. A recipe data record could not be transferred between the HMI and the PLC.
Check recipe configuration in WinCC flexible. Verify PLC data block size matches the recipe structure. Ensure sufficient memory is available on the HMI device.
Event ID: 1000080: Internal device error. A hardware or firmware fault has been detected within the HMI panel.
Perform a warm restart of the panel. If the error persists, back up the project, perform a factory reset, and reload the project. Contact Siemens technical support if the fault recurs.

Frequently Asked Questions

What PLC systems are compatible with the SIMATIC MP 377?

The MP 377 is compatible with Siemens SIMATIC S7-300, S7-400, S7-1200, S7-1500, and S5 series PLCs via PROFIBUS DP or PROFINET. It also supports communication with third-party controllers through OPC and serial protocols.

What software is required to program and configure the MP 377?

The MP 377 is configured using Siemens WinCC flexible 2008 or later. Projects can also be migrated and used with TIA Portal WinCC in some configurations.

What is the supply voltage for the 6AV6146-4MM41-0KY2?

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

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

The front panel of the MP 377 achieves IP65 protection, making it resistant to dust ingress and low-pressure water jets when correctly installed in a panel cutout.

Does the MP 377 support data logging and recipe management?

Yes, the MP 377 supports data logging, trend displays, alarm logging, and recipe management through the WinCC flexible runtime environment, with data storable on internal flash memory or external USB media.

Troubleshooting

Display remains blank after power on

Measure the 24 V DC supply voltage at the panel's power connector. Check that the supply is within the specified tolerance. Inspect the internal fuse if accessible.

Ensure the 24 V DC supply is stable and within tolerance. If the supply is correct and the display remains blank, the internal power supply board or backlight inverter may have failed and the unit should be sent for repair or replacement.

Touchscreen does not respond or responds inaccurately

Attempt to operate the panel using an external USB mouse to determine if the issue is isolated to the touchscreen. Check for physical damage or contamination on the touch surface.

Perform a touchscreen recalibration through the Windows CE Control Panel or the Siemens Start Center. Clean the touch surface with a soft, dry cloth. If calibration does not resolve the issue, the resistive touch overlay may require replacement.

HMI cannot communicate with the PLC over PROFINET

Verify the Ethernet cable connection and check the link LEDs on the RJ45 port. Ping the PLC IP address from the HMI network settings. Confirm that the IP address, subnet mask, and device name configured in the project match the actual network settings.

Correct any IP address or device name mismatches in the WinCC flexible project and reload the project to the panel. Replace the Ethernet cable if no link is detected. Check switch or network infrastructure for faults.

Panel repeatedly restarts or crashes during runtime

Check the operating temperature around the panel and ensure ventilation clearances are maintained. Review the system event log in WinCC flexible for recurring event IDs. Check available flash memory on the device.

Reduce ambient temperature if overheating is suspected. Delete unnecessary data logs or archived files to free flash memory. If crashes persist, perform a firmware update or factory reset and reload the project.

Project transfer from engineering PC fails

Verify the network connection between the PC and the HMI panel. Ensure the panel is in Transfer mode via the Start Center. Check that the WinCC flexible version on the PC is compatible with the panel firmware version.

Switch the panel to Transfer mode manually through the Start Center. Confirm firewall settings on the engineering PC are not blocking the transfer. Update panel firmware if a version mismatch is identified.
