Common Error Codes & System Events

Event ID: 1000: System startup completed. The HMI device has successfully booted and the runtime environment is initialized.
No action required. This is an informational event confirming normal startup.
Event ID: 10000: Connection to PLC lost. The HMI panel cannot establish or has lost communication with the configured PLC.
Check PROFIBUS/PROFINET cabling and connector integrity. Verify PLC is powered and running. Confirm station address and network settings in the HMI project configuration.
Event ID: 10001: Connection to PLC established. Communication between the HMI panel and the PLC has been successfully restored.
No action required. This is an informational event confirming restored communication.
Event ID: 20000: Tag read error. The HMI runtime was unable to read a configured tag from the PLC.
Verify the tag address exists in the PLC program. Check data block numbers and variable addresses in WinCC flexible or TIA Portal project. Ensure PLC program is not in STOP mode.
Event ID: 40000: Project transfer active. A project download to the HMI device is in progress.
No action required during intentional transfers. If unexpected, check for unauthorized access to the panel network connection.
Event ID: 70010: Internal flash memory error. A read or write operation to the internal flash memory has failed.
Restart the HMI device. If the error persists, back up the project and perform a factory reset. Replace the unit if the flash memory is physically damaged.
Event ID: 110000: Backup/restore operation failed. An error occurred during project backup or restore via CF card or USB.
Check the CF card or USB storage device for errors and sufficient free space. Reformat the storage medium if necessary and retry the operation.

Frequently Asked Questions

What PLC systems is the SIMATIC MP 377 15" Touch compatible with?

The MP 377 is compatible with Siemens S7-300, S7-400, S7-1200, and S7-1500 PLCs via MPI, PROFIBUS DP, or PROFINET/Ethernet. It can also communicate with third-party controllers using standard protocols such as Modbus TCP or OPC.

What software is used to configure and program the 6AV6146-4MM40-2KY2?

This panel is configured using Siemens WinCC flexible 2008 or SIMATIC WinCC (TIA Portal). Projects created in WinCC flexible can be transferred to the panel via Ethernet, USB, or CF card.

What is the supply voltage for the MP 377 15" Touch?

The panel requires a 24 V DC power supply. It is recommended to use a regulated SELV power supply meeting IEC 60364-4-41 requirements.

Does the MP 377 support remote access or VNC functionality?

Yes, the SIMATIC MP 377 supports Sm@rtAccess and Sm@rtService functions, allowing remote monitoring and control via VNC-compatible clients over an Ethernet network.

What is the IP protection rating of the front panel?

The front panel of the MP 377 15" Touch carries an IP65 protection rating, making it resistant to dust ingress and low-pressure water jets, suitable for installation in industrial enclosures.

Troubleshooting

Display remains blank after power on

Measure the 24 V DC supply voltage at the power connector on the rear of the panel. Check that the voltage is within the acceptable range. Inspect the internal fuse if accessible.

Ensure the power supply is providing stable 24 V DC. Replace the power supply if voltage is out of range. If the backlight has failed, the panel may require backlight or display assembly replacement.

Touchscreen does not respond or responds inaccurately

Attempt to recalibrate the touchscreen via the Control Panel in the Start menu of the panel OS. Check for physical damage or contamination on the touch surface.

Perform a touchscreen recalibration through the SIMATIC HMI Control Panel. Clean the screen surface with a soft, dry cloth. If calibration fails repeatedly, the touchscreen overlay may need replacement.

HMI cannot communicate with the PLC over PROFIBUS

Check the PROFIBUS cable connections and termination resistors at both ends of the network segment. Verify the PROFIBUS station address configured on the HMI matches the project settings.

Reseat the PROFIBUS connector and ensure correct bus termination is applied. Confirm the station address in the HMI Control Panel under PROFIBUS settings matches the WinCC flexible project configuration. Replace the PROFIBUS cable if continuity testing reveals a fault.

Panel freezes or restarts unexpectedly during operation

Check the supply voltage for ripple or voltage drops under load. Review the system event log in WinCC flexible Runtime for recurring error event IDs. Check for overheating by measuring ambient temperature around the panel.

Stabilize the 24 V DC power supply and ensure adequate ventilation around the panel. Update the HMI firmware to the latest compatible version. If the issue persists, back up the project and perform a factory reset, then reload the project.

CF card is not recognized by the panel

Inspect the CF card slot for debris or bent contacts. Test the CF card in a separate card reader to verify it is not corrupted or faulty.

Clean the CF card slot contacts carefully. Reformat the CF card to FAT32 using a PC and retry. Replace the CF card if it is found to be defective. Ensure the card capacity and type are compatible with the MP 377 specifications.
