Common Error Codes & System Events

Event ID: 10000: Connection to PLC lost or communication timeout on configured connection.
Check Ethernet or PROFIBUS cable connections, verify PLC is powered and running, and confirm IP address or PROFIBUS address settings in WinCC flexible project.
Event ID: 10001: Communication error: PLC is not responding within the configured timeout period.
Verify PLC program is in RUN mode, check network configuration, and ensure the correct communication driver is loaded on the HMI.
Event ID: 20000: Project download failed or project data is corrupted.
Re-download the WinCC flexible project from the engineering PC, ensure compatible runtime version is installed on the panel, and check USB or Ethernet connection during transfer.
Event ID: 40000: System memory low: available user memory is critically low.
Reduce project size, remove unused images or scripts, and consider archiving historical data to an external storage device.
Event ID: 50000: Runtime application has crashed or stopped unexpectedly.
Restart the HMI panel. If the problem persists, reload the project and check for script errors or unsupported function calls in the WinCC flexible project.
Event ID: 70000: Backup battery low or battery failure detected.
Replace the internal backup battery (CR2032 or equivalent as specified in the device manual) to prevent loss of time/date settings and retain data.
Event ID: 110000: Tag limit exceeded: the number of configured tags exceeds the licensed limit for the runtime.
Reduce the number of tags in the WinCC flexible project or upgrade the runtime license to support a higher tag count.

Frequently Asked Questions

What PLC families are compatible with the Siemens MP 377 (6AV6146-1LP00-2KB1)?

The MP 377 is compatible with SIMATIC S7-300, S7-400, S7-1500, and S7-200 PLCs, as well as third-party controllers via OPC or serial communication drivers configured in WinCC flexible.

What software is required to program or configure this HMI panel?

The MP 377 is configured using Siemens WinCC flexible 2008 or later. Projects are created on a PC and downloaded to the panel via Ethernet or USB connection.

What is the input voltage requirement for the 6AV6146-1LP00-2KB1?

The panel requires a 24 V DC power supply, typically with a tolerance of 18 V DC to 30 V DC, and consumes a maximum of approximately 60 W.

Does the MP 377 support PROFINET communication?

Yes, the MP 377 includes an integrated Ethernet port that supports PROFINET IO communication, allowing direct connection to PROFINET-capable PLCs and network infrastructure.

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

The front panel of the MP 377 is rated IP65, making it resistant to dust ingress and low-pressure water jets, suitable for use in industrial panel doors and enclosures.

Troubleshooting

Display remains blank after power on

Measure 24 V DC at the power supply connector on the rear of the panel. Check that the supply voltage is within the 18–30 V DC range. Inspect the internal fuse if accessible.

Ensure a stable 24 V DC supply is connected correctly. If the supply is confirmed good but the display remains off, the internal power supply board or backlight inverter may require replacement.

Touchscreen does not respond or responds inaccurately

Attempt to recalibrate the touchscreen via the Windows CE Control Panel or the Siemens Start Center. Check for physical damage or contamination on the screen surface.

Perform a touchscreen recalibration. If calibration does not resolve the issue, the resistive touch overlay may be worn or damaged and will need to be replaced.

HMI cannot establish communication with the PLC

Verify the Ethernet or PROFIBUS cable is connected and undamaged. Confirm the IP address or PROFIBUS station address configured on the HMI matches the PLC project settings. Ping the PLC from the HMI network settings.

Correct any IP address or PROFIBUS address mismatches in the WinCC flexible project. Replace faulty cables or connectors. Ensure the PLC is in RUN mode and the correct communication driver is active.

Panel reboots repeatedly or fails to load the runtime project

Check available user memory via the Siemens Start Center. Inspect the project for corrupted files or incompatible runtime version. Review event logs in Windows CE for crash reports.

Re-download the WinCC flexible project from the engineering PC. If the panel continues to reboot, perform a factory reset via the Start Center and reload the project and runtime software.

Date and time reset to default after power cycle

This typically indicates a depleted or failed internal backup battery, which maintains the real-time clock when the panel is powered off.

Replace the internal backup battery with the correct type as specified in the MP 377 hardware manual. After replacement, reconfigure the date and time settings.
