Description
Additional information

The Siemens 6AV6146-3LP40-2KA2 is a Multi Panel (MP 370) belonging to the SIMATIC HMI family, designed for demanding visualization and operator control tasks in industrial automation environments. This panel features a 15-inch TFT display and is part of the MP 370 series, which represents a high-performance class of operator panels capable of running WinCC flexible runtime software. It is manufactured by Siemens and combines robust hardware with versatile communication capabilities.

The MP 370 panel is equipped with a 15-inch TFT color display with a resolution of 1024 x 768 pixels (XGA), offering clear and detailed visualization of process data. It supports both touch screen and key operation, providing flexible interaction options for operators. The unit includes multiple communication interfaces such as MPI, PROFIBUS DP, and Ethernet (TCP/IP), enabling integration into a wide range of automation network architectures. Onboard memory supports project storage and runtime operation, and the panel runs on a Windows CE operating system, allowing execution of WinCC flexible projects.

The SIMATIC MP 370 is widely used in machine building, automotive manufacturing, process industries, and factory automation where a large, high-resolution display and robust connectivity are required. Its compatibility with Siemens S7-300 and S7-400 PLCs makes it a natural fit for existing SIMATIC automation infrastructure. The panel is suited for control cabinet door mounting and applications where operators require detailed graphical overviews of complex processes.

Common Error Codes & System Events

Event ID: 10000: Connection to the PLC could not be established or was interrupted during runtime.
Check communication cable connections, verify MPI/PROFIBUS address settings, and confirm the PLC is powered and in RUN mode.
Event ID: 10001: Communication timeout occurred between the HMI panel and the configured PLC controller.
Verify network configuration parameters, check for cable faults, and ensure correct baud rate settings on both the panel and PLC.
Event ID: 20000: Project download failed or project data is corrupt on the panel.
Re-download the project using WinCC flexible, check USB or Ethernet transfer connection, and verify sufficient panel memory is available.
Event ID: 40000: System memory is critically low, which may cause runtime instability.
Reduce project size, close unnecessary runtime applications, and consider archiving or deleting unused data records from the panel.
Event ID: 50000: Internal hardware fault detected, potentially related to the display or mainboard.
Perform a panel restart. If the fault persists, check internal connections and consider sending the unit for repair or replacement.
Event ID: 60000: Configuration error detected; a tag or screen object references an invalid or missing PLC variable.
Open the project in WinCC flexible, locate and correct all invalid tag references, then re-download the project to the panel.
Event ID: 70000: Backup battery low or battery failure detected, risking loss of retained data.
Replace the internal backup battery with the correct Siemens-specified replacement and verify retained data integrity after replacement.

Frequently Asked Questions

Which software is used to configure and program the SIMATIC MP 370?

The MP 370 is configured using Siemens WinCC flexible software. Projects are created on a PC and then downloaded to the panel via MPI, PROFIBUS, USB, or Ethernet.

What PLC families are compatible with the SIMATIC MP 370?

The MP 370 is compatible with Siemens SIMATIC S7-300, S7-400, S7-200, and also supports connections to third-party controllers via supported communication drivers.

What communication interfaces are available on the 6AV6146-3LP40-2KA2?

This panel provides MPI, PROFIBUS DP, Ethernet (TCP/IP), and RS-422/485 serial interfaces, supporting a wide range of network topologies and PLC connections.

What is the display size and resolution of this panel?

The 6AV6146-3LP40-2KA2 features a 15-inch TFT color display with a resolution of 1024 x 768 pixels (XGA) and supports up to 64,000 colors.

What is the front panel IP protection rating of the MP 370?

The front panel of the MP 370 carries an IP65 protection rating, making it resistant to dust ingress and low-pressure water jets when correctly installed in a panel cutout.

Troubleshooting

Display remains blank after power is applied

Measure the 24 V DC supply voltage at the panel power connector. Check that the supply is within the specified tolerance and that the connector is fully seated.

Correct any supply voltage issues. If the supply is confirmed good and the display remains blank, the internal power supply board or display backlight inverter may have failed and the unit should be inspected for repair.

Touchscreen does not respond or responds inaccurately to touch input

Check whether the panel responds to key inputs if keys are present. Attempt a touchscreen recalibration from the panel's Start Center or Control Panel settings.

Recalibrate the touchscreen using the built-in calibration utility. If the issue persists after calibration, the touch overlay may be damaged or the touch controller board may require replacement.

Panel fails to establish communication with the S7 PLC

Verify MPI or PROFIBUS cable connections and check that the panel's configured PLC address matches the actual PLC station address. Confirm the baud rate settings are identical on both devices.

Correct any address or baud rate mismatches in the WinCC flexible project settings and re-download. Replace the communication cable if continuity testing reveals a fault.

Project download from PC to panel fails repeatedly

Check the transfer cable or Ethernet connection between the PC and panel. Ensure the panel is set to Transfer mode via the Start Center and that WinCC flexible is using the correct communication channel.

Switch the panel to Transfer mode manually, verify the correct COM port or IP address is selected in WinCC flexible, and retry the download. If using a serial cable, try an alternative USB or Ethernet transfer method.

Panel reboots unexpectedly or shows runtime crashes

Check the 24 V DC supply for voltage dips or instability under load. Review the panel's event log in WinCC flexible for recurring event IDs that may indicate the root cause.

Stabilize the power supply by ensuring adequate current capacity. If the issue is software-related, re-download the project after checking for corrupt screens or invalid tag references in WinCC flexible.
