Common Error Codes & System Events

Event ID: 10000: Communication error between the HMI panel and the connected PLC or controller. The configured connection cannot be established.
Check the communication cable and connector integrity. Verify the PLC address settings and communication parameters in the WinCC flexible project. Ensure the PLC is powered and in RUN mode.
Event ID: 10001: Connection to the PLC was interrupted during runtime after a previously successful connection.
Check network or PROFIBUS cabling for loose connections. Verify PLC is still in RUN mode. Restart the HMI runtime and check for electromagnetic interference on the communication line.
Event ID: 20000: Tag read error — the HMI is unable to read a configured tag from the PLC.
Verify the tag address in the WinCC flexible project matches the actual PLC data block or memory area. Check that the PLC program has not been modified to remove or relocate the referenced address.
Event ID: 20001: Tag write error — the HMI is unable to write a value to the configured PLC tag.
Check that the target PLC memory area is not write-protected. Verify the tag address configuration in the WinCC flexible project and confirm the PLC is in a state that accepts write commands.
Event ID: 40000: Recipe data error — a recipe record could not be read from or written to the configured storage location.
Check the storage medium (CompactFlash card or internal flash) for available space and integrity. Re-transfer the project to the panel and verify recipe configuration settings in WinCC flexible.
Event ID: 70000: System error — the HMI runtime has encountered an internal software fault or the project file is corrupted.
Perform a controlled restart of the panel. If the error persists, re-transfer the WinCC flexible project to the panel using a PC with ProSave or WinCC flexible software. Check for firmware compatibility.
Event ID: 50000: Alarm logging error — the HMI cannot write alarm entries to the configured data log or storage medium.
Check available storage space on the CompactFlash card or internal memory. Verify alarm log configuration in the WinCC flexible project and ensure the storage path is correctly defined.

Frequently Asked Questions

What display size does the 6AV6146-1LP00-1KC1 have?

What communication protocols does the MP 377 support?

The MP 377 supports PROFIBUS DP, MPI, and Ethernet (PROFINET) for PLC communication, as well as USB ports for peripheral devices such as keyboards, mice, and USB storage.

Which Siemens PLCs is the MP 377 compatible with?

The MP 377 is compatible with SIMATIC S7-300, S7-400, S7-1200, and S7-1500 PLCs, as well as other controllers supported by WinCC flexible, including third-party controllers via appropriate drivers.

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 transferred to the panel via Ethernet, USB, or MPI/PROFIBUS connection using ProSave or directly from WinCC flexible.

What is the front panel protection rating of the 6AV6146-1LP00-1KC1?

The front panel of the MP 377 is rated IP65, making it suitable for installation in environments where protection against dust and water jets is required.

Troubleshooting

Display remains blank after power on

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

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

Touchscreen does not respond or responds inaccurately

Attempt to operate the panel using the physical keypad if available. Check whether the touch issue is localized to a specific area of the screen or affects the entire surface.

Perform a touchscreen recalibration through the panel's Control Panel settings in Windows CE. If recalibration does not resolve the issue, the resistive touch overlay may be damaged and requires replacement.

HMI cannot establish communication with the PLC

Verify the communication cable type and wiring. Check the IP address, subnet mask, and PROFIBUS node address settings on both the HMI and the PLC. Use a network diagnostic tool to confirm connectivity.

Correct any mismatched communication parameters in the WinCC flexible project and re-transfer the project to the panel. Replace the communication cable if continuity testing reveals a fault.

Panel repeatedly restarts or crashes during runtime

Check the operating temperature of the installation environment. Review the system event log accessible via the panel's Start menu for recurring Event IDs. Verify the project file integrity.

Ensure adequate ventilation around the panel to prevent overheating. Re-transfer the WinCC flexible project to the panel. If instability continues, perform a firmware update using ProSave and the latest firmware package from Siemens support.

CompactFlash card not recognized by the panel

Remove and reinsert the CompactFlash card. Check the card in another device to confirm it is functional. Inspect the card slot on the panel for bent pins or debris.

Format the CompactFlash card using the panel's built-in formatting tool in Windows CE Control Panel. If the card is recognized in another device but not the panel, the CompactFlash slot on the panel may require repair or replacement.
