Common Error Codes & System Events

Event ID: 10000: Communication error between HMI panel and PLC. Connection to the configured controller cannot be established or has been lost.
Check PROFIBUS/MPI/Ethernet cabling and connector integrity. Verify PLC address settings match HMI project configuration. Restart both PLC and HMI panel.
Event ID: 10001: Tag read error. The HMI panel cannot 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 project. Ensure PLC is in RUN mode.
Event ID: 10002: Tag write error. The HMI panel cannot write a value to a configured PLC tag.
Check that the target PLC data area is not write-protected. Verify tag address and data type consistency between HMI project and PLC program.
Event ID: 20000: System memory low. Available RAM on the HMI panel is critically low, which may cause instability or application errors.
Reduce the number of simultaneously open screens or active scripts. Optimize the HMI project to reduce memory usage. Restart the panel to free memory.
Event ID: 40000: Project download error. Transfer of the HMI project from the engineering PC to the panel failed.
Check USB or Ethernet transfer cable connections. Ensure the panel is in Transfer mode. Verify WinCC flexible version compatibility with the panel firmware version.
Event ID: 50000: Firmware update error. Panel firmware update process failed or was interrupted.
Restart the panel and attempt the firmware update again using ProSave or WinCC flexible. Ensure the correct firmware version for this panel type is used and the power supply is stable during the update.
Event ID: 70000: Recipe data error. An error occurred during reading or writing of recipe data records.
Check available flash memory on the panel. Verify recipe configuration in the WinCC flexible project. Re-transfer the project if recipe structure has been modified.

Frequently Asked Questions

What engineering software is required to configure the MP 377 15" Touch?

The 6AV6146-3MM41-2KY2 is configured using Siemens WinCC flexible 2008 or later. It is also supported in TIA Portal via the WinCC flexible integration package.

Which PLC families are compatible with this HMI panel?

The MP 377 supports communication with SIMATIC S7-200, S7-300, S7-400, and S7-1200 PLCs via MPI, PROFIBUS DP, or PROFINET/Ethernet interfaces. Third-party controllers with supported drivers can also be connected.

What is the supply voltage for the 6AV6146-3MM41-2KY2?

The panel requires a 24 V DC power supply. The permissible voltage range is typically 19.2 V DC to 28.8 V DC.

Does this panel support remote access or web-based visualization?

The MP 377 supports Sm@rtAccess and Sm@rtService functions, allowing remote monitoring and control via a standard web browser over an Ethernet network connection.

What is the IP protection rating of the MP 377 15" Touch?

The front face of the panel is rated IP65, making it suitable for panel door mounting in environments with dust and water spray. The rear of the unit is rated IP20.

Troubleshooting

Display remains blank after power on

Measure 24 V DC supply voltage at the power connector on the rear of the panel. Check that the voltage is within the 19.2–28.8 V DC range. Inspect the internal fuse if accessible.

Correct the power supply voltage if out of range. If the supply is correct and the display remains blank, the backlight or internal power board may have failed and the unit should be sent for repair or the backlight replaced.

Touchscreen does not respond or responds inaccurately

Determine whether the issue is a complete lack of response or positional inaccuracy. A miscalibrated touch panel will show offset touch registration, while a hardware failure will show no response at all.

Recalibrate the touchscreen via the Windows CE Control Panel under the Siemens Start menu. If calibration does not resolve the issue, the resistive touch overlay may be damaged and requires replacement.

HMI cannot establish communication with the PLC

Check physical cabling on the PROFIBUS, MPI, or Ethernet port. Verify the PLC address and network settings in the HMI project match the actual PLC configuration. Use the panel's diagnostic functions to check connection status.

Correct any address mismatches in the WinCC flexible project and re-download. Replace faulty cables or connectors. Ensure the PLC is powered and in RUN mode.

Panel repeatedly restarts or crashes during operation

Check for overheating by verifying ambient temperature is within the 0–50 °C operating range. Review system event logs on the panel for recurring Event IDs. Check available flash and RAM memory.

Improve ventilation around the panel. Optimize the HMI project to reduce memory load. If crashes persist, perform a firmware update using ProSave and re-download the project. A persistent issue may indicate a hardware fault requiring repair.

Project transfer from PC to panel fails

Verify the panel is set to Transfer mode (accessible via the Siemens Start menu or on startup). Check the Ethernet or USB transfer cable. Confirm the WinCC flexible version is compatible with the installed panel firmware.

Update the panel firmware to match the WinCC flexible version using ProSave. Use a known-good transfer cable. If using Ethernet, ensure both PC and panel are on the same network subnet.
