Description
Additional information

The Siemens 6AV6146-3LP40-2KB2 is a Multi Panel (MP 370) belonging to the SIMATIC HMI family, designed for demanding machine-level and process visualization tasks. This panel operates as a high-performance operator interface unit capable of running both WinCC flexible and SIMATIC ProTool runtime environments. It is part of Siemens' established SIMATIC HMI panel range, offering a robust platform for industrial human-machine interface applications.

The MP 370 features a 15-inch TFT color display with a resolution of 1024 x 768 pixels and supports touch screen operation as well as an integrated keyboard. It is equipped with a 133 MHz processor, 12 MB user memory, and runs on Microsoft Windows CE, enabling multitasking and the use of standard software components. Communication interfaces include PROFIBUS DP, MPI, and an Ethernet port (10/100 Mbit/s), along with serial RS-232 and RS-422/485 ports, providing broad connectivity to Siemens S7 PLCs and third-party controllers. The unit operates on a 24 V DC supply and carries CE and UL certifications.

The SIMATIC MP 370 is widely deployed in machine building, automotive manufacturing, food and beverage processing, and chemical plant environments where a large, high-resolution display and flexible communication options are required. Its ability to connect via PROFIBUS and Ethernet makes it suitable for integration into both legacy and modern automation architectures. The panel's rugged construction and wide operating temperature range allow reliable operation in industrial shop-floor conditions.

Common Error Codes & System Events

Event ID: 10000: Configuration error detected during startup; the project loaded on the panel contains configuration inconsistencies.
Reload the project using WinCC flexible or ProTool. Verify the project configuration is compatible with the MP 370 firmware version.
Event ID: 20000: Communication link to the PLC has been interrupted or cannot be established.
Check PROFIBUS/MPI or Ethernet cabling and termination resistors. Verify PLC address settings match the HMI project configuration.
Event ID: 40000: Tag read/write error; the HMI panel cannot access a configured PLC tag.
Verify the tag address in the WinCC flexible project. Confirm the PLC program contains the referenced data block or memory area.
Event ID: 50000: Overflow of the alarm buffer; too many alarms generated in a short period.
Review alarm configuration in the project. Increase alarm buffer size or reduce the frequency of alarm triggers in the PLC logic.
Event ID: 70000: Project transfer error; data transfer between the engineering PC and the panel was interrupted.
Check the transfer cable or Ethernet connection. Restart the panel in transfer mode and retry the project download from WinCC flexible.
Event ID: 110000: System memory low; available runtime memory on the panel is insufficient for the loaded project.
Reduce the project size by optimizing graphics and scripts. Ensure no unnecessary background applications are running on the Windows CE environment.
Event ID: 130000: Firmware update error; the firmware update process was not completed successfully.
Repeat the firmware update procedure using the correct firmware version for the MP 370. Ensure stable power supply during the update process.

Frequently Asked Questions

What communication protocols does the SIMATIC MP 370 (6AV6146-3LP40-2KB2) support?

The MP 370 supports PROFIBUS DP, MPI, Ethernet (10/100 Mbit/s), RS-232, and RS-422/485 interfaces. This allows connectivity to Siemens S7-300, S7-400 PLCs as well as third-party controllers via serial protocols.

Which engineering software is used to configure the MP 370?

The MP 370 is configured using Siemens WinCC flexible or the older ProTool engineering software. WinCC flexible is the recommended tool for creating and transferring HMI projects to this panel.

What is the display size and resolution of the 6AV6146-3LP40-2KB2?

This unit features a 15-inch TFT color display with a resolution of 1024 x 768 pixels, supporting up to 64,000 colors.

Is the MP 370 compatible with SIMATIC S7-1200 or S7-1500 PLCs?

The MP 370 has limited compatibility with newer S7-1200 and S7-1500 PLCs. Communication is possible via Ethernet using older driver configurations, but WinCC flexible does not natively support the full feature set of these newer controllers. TIA Portal-based panels are recommended for S7-1200/1500 systems.

What is the operating voltage of the SIMATIC MP 370?

The panel operates on a 24 V DC supply voltage. Ensure a stable, regulated 24 V DC power source is used to avoid operational issues.

Troubleshooting

Display remains blank after power on

Check the 24 V DC supply voltage at the power connector. Verify the internal fuse and inspect the backlight status by shining an external light on the display surface to detect faint images.

If supply voltage is correct and a faint image is visible, the backlight inverter or CCFL backlight lamp has failed and requires replacement. If no image is visible at all, inspect the internal power supply board for damage.

Touchscreen does not respond or responds inaccurately

Attempt to recalibrate the touch screen through the Windows CE control panel or the SIMATIC HMI startup menu. Check for physical damage or contamination on the touch surface.

Perform a touch screen recalibration via the panel's startup dialog. If calibration does not resolve the issue, the resistive touch overlay may be worn or damaged and should be replaced.

Panel fails to establish communication with the PLC

Verify the PROFIBUS or MPI address configured in the HMI project matches the physical DIP switch or software settings on the panel. Check cable integrity and bus termination at both ends of the PROFIBUS network.

Correct any address mismatches in the WinCC flexible project and retransfer. Replace damaged PROFIBUS cables and ensure proper 120-ohm termination resistors are installed at both ends of the bus segment.

Project transfer from PC to panel fails or times out

Check the Ethernet or serial transfer cable connection. Confirm the panel is set to transfer mode (accessible via the Start Center on boot). Verify the PC firewall is not blocking the WinCC flexible transfer port.

Restart the panel and select transfer mode from the Start Center. Disable PC firewall temporarily during transfer or add WinCC flexible to the firewall exceptions. Use a direct Ethernet connection rather than a network switch if possible.

Panel reboots repeatedly or freezes during operation

Check for project configuration errors or memory overload. Connect a USB keyboard and mouse to access the Windows CE desktop and review system event logs. Inspect the 24 V DC supply for voltage fluctuations.

Reload a known-good project version. Ensure the 24 V DC supply is stable and within specification. If the issue persists, perform a factory reset via the SIMATIC HMI Start Center and reload the project from scratch.
