Description
Additional information

The Siemens 6AV6446-1BA40-2BB3 is a Multi Panel (MP 370) belonging to the SIMATIC HMI family, designed for demanding machine-level and process visualization tasks. This unit features a 12-inch TFT display and is part of the MP 370 series, which offers high-performance panel computing capabilities for industrial environments. It is manufactured by Siemens and represents a robust operator panel solution within the SIMATIC HMI product line.

The MP 370 (6AV6446-1BA40-2BB3) is equipped with a 12" TFT color display with a resolution of 800 x 600 pixels (SVGA) and supports touch screen operation. It provides multiple communication interfaces including MPI, PROFIBUS DP, and Ethernet (TCP/IP), enabling integration with a wide range of Siemens SIMATIC PLCs and third-party controllers. The panel runs on Windows CE and supports configuration via WinCC flexible software, with onboard flash memory and expandable storage via CompactFlash card slots.

The MP 370 is widely deployed in machine building, automotive manufacturing, food and beverage processing, and chemical plant environments where a large, high-resolution display with robust connectivity is required. Its compatibility with SIMATIC S7-300, S7-400, and other controller families makes it suitable for complex SCADA and HMI applications at the machine or cell level. The panel's industrial-grade construction and wide operating temperature range make it appropriate for use in demanding production floor conditions.

Common Error Codes & System Events

Event ID: 1000000: System startup completed successfully. The HMI panel has booted and the runtime environment is active.
No action required. This is an informational event confirming normal startup.
Event ID: 1000002: Connection to PLC lost. Communication between the HMI panel and the configured controller has been interrupted.
Check MPI/PROFIBUS/Ethernet cabling and connector integrity. Verify PLC is powered and running. Check communication parameters (address, baud rate) in WinCC flexible project.
Event ID: 1000003: Tag read error. The HMI panel is 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 the WinCC flexible configuration. Ensure PLC program is loaded and running.
Event ID: 1000004: Tag write error. The HMI panel failed to write a value to a PLC tag.
Check that the target PLC address is not write-protected. Verify the tag address and data type match the PLC configuration. Confirm communication link is active.
Event ID: 1000010: Project download failed. Transfer of the WinCC flexible project to the panel was unsuccessful.
Ensure the panel is in Transfer mode. Verify the communication interface settings match between PC and panel. Check that the WinCC flexible version is compatible with the panel firmware version.
Event ID: 1000020: Backup/restore error. A project backup or restore operation could not be completed.
Check that the CompactFlash card is properly inserted and has sufficient free space. Verify the card is not write-protected. Retry the operation or replace the CompactFlash card.
Event ID: 1000030: Screen saver or display timeout active. The display has been dimmed or switched off due to inactivity.
Touch the screen or press any key to reactivate the display. Adjust the screen saver timeout settings in the panel Control Panel if required.
Event ID: 1000040: Firmware update error. The panel firmware update process was interrupted or failed.
Restart the panel and retry the firmware update using the ProSave tool. Ensure the correct firmware version for the 6AV6446-1BA40-2BB3 is used and that power is stable during the update process.

Frequently Asked Questions

What display size and resolution does the 6AV6446-1BA40-2BB3 offer?

The MP 370 panel features a 12-inch TFT color display with a resolution of 800 x 600 pixels (SVGA). It supports resistive touch screen input.

Which PLCs are compatible with the SIMATIC MP 370?

The MP 370 is compatible with Siemens SIMATIC S7-200, S7-300, S7-400, and S7-1200/1500 series PLCs via MPI, PROFIBUS DP, or Ethernet interfaces. It also supports communication with third-party controllers via serial protocols.

What software is used to configure the MP 370 panel?

The MP 370 is configured using Siemens WinCC flexible software. Projects are transferred to the panel via MPI, PROFIBUS, Ethernet, or USB connection.

What is the supply voltage for the 6AV6446-1BA40-2BB3?

The panel requires a 24 V DC power supply. Ensure the power source is stable and within the specified tolerance range to prevent operational issues.

Can the MP 370 panel memory be expanded?

Yes, the MP 370 supports memory expansion via a CompactFlash card slot, which can be used for project storage, data logging, and recipe management.

Troubleshooting

Display remains blank after power on

Check that 24 V DC is present at the power supply terminals. Verify the power connector is fully seated. Check whether the screen saver is active by touching the screen.

Restore correct 24 V DC supply voltage. If the screen saver is active, touch the display to wake it. If the display remains blank with correct power applied, the backlight or internal power supply board may require replacement.

HMI panel fails to communicate with PLC

Check the MPI, PROFIBUS, or Ethernet cable connections. Verify the bus address and baud rate settings on both the panel and PLC match. Use the panel's diagnostic tools to check connection status.

Correct any address or baud rate mismatches in the WinCC flexible project settings. Replace damaged cables or connectors. Ensure the PLC is in RUN mode and the network is properly terminated.

Touch screen does not respond or is inaccurate

Determine whether the touch screen is completely unresponsive or only inaccurate in certain areas. Access the touch calibration utility via the Windows CE Control Panel if the panel is operational.

Recalibrate the touch screen using the calibration tool in the Windows CE Control Panel. If the touch screen is completely unresponsive, inspect the touch controller connection internally or replace the touch screen assembly.

Project transfer from PC to panel fails

Confirm the panel is set to Transfer mode. Check that the communication interface (Ethernet IP address, MPI address) matches the settings in WinCC flexible. Verify the PC firewall is not blocking the transfer.

Set the correct transfer channel on the panel via the Loader menu. Align the communication parameters between the PC and panel. Disable firewall software temporarily during transfer or add an exception for WinCC flexible.

Panel displays 'No project loaded' after startup

The internal flash memory may not contain a valid project, or the project may have been corrupted. Check whether a CompactFlash card with a project is inserted.

Re-transfer the WinCC flexible project to the panel using ProSave or WinCC flexible. If the internal memory is corrupted, perform a panel reset and reload the firmware before transferring the project again.
