€ 2.995,00
The Siemens 6AV6146-3LP40-3KA2 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 15-inch TFT display and is part of Siemens' high-performance operator panel range, offering robust graphical visualization capabilities for industrial environments. The MP 370 series bridges the gap between standard operator panels and full PC-based SCADA systems.
The 6AV6146-3LP40-3KA2 is equipped with a touch-screen interface and supports communication via PROFIBUS DP and MPI interfaces, enabling direct integration with SIMATIC S7 PLCs. It runs WinCC flexible runtime software, providing a powerful environment for creating and executing HMI applications with support for scripting, trends, alarms, and recipes. The panel includes onboard flash memory for project storage and supports external memory expansion via CompactFlash cards. The unit operates on a 24 V DC supply and is built to meet industrial environmental requirements.
The SIMATIC MP 370 is widely deployed in manufacturing automation, machine tool control, packaging machinery, and process plant environments. Its large display area and touch operation make it suitable for applications requiring detailed process overviews and operator interaction at the machine level. The panel is compatible with the broader SIMATIC automation ecosystem, making it a practical choice for system integrators working with Siemens S7-300 and S7-400 controller platforms.

Common Error Codes & System Events
- Event ID: 10000
- Configuration error detected during project load; project data may be corrupt or incompatible with the runtime version.
Re-transfer the project using WinCC flexible. Ensure the runtime version on the panel matches the project configuration version. - Event ID: 10001
- Communication connection to the PLC has been lost or cannot be established.
Check PROFIBUS/MPI cable connections and termination resistors. Verify PLC address settings match the HMI project configuration. - Event ID: 20000
- System memory low; available RAM for runtime operation is insufficient.
Reduce the number of active screens or objects. Optimize the project to reduce memory usage and re-transfer. - Event ID: 40000
- Tag read/write error; the HMI cannot read or write a configured tag from/to the controller.
Verify the tag address in the project matches the actual PLC data block or memory address. Check PLC program for address conflicts. - Event ID: 70000
- Recipe data error; recipe record cannot be read or written correctly.
Check recipe configuration in WinCC flexible. Verify sufficient storage space on the CompactFlash card and that the card is properly seated. - Event ID: 110000
- Alarm logging error; the alarm buffer is full or the logging destination is unavailable.
Acknowledge and clear pending alarms. Check CompactFlash card availability and free space for alarm log files. - Event ID: 130000
- Screen object configuration error; one or more display objects cannot be rendered due to missing or invalid configuration.
Review the project in WinCC flexible for misconfigured screen objects. Correct and re-transfer the project to the panel.
Frequently Asked Questions
What communication interfaces does the 6AV6146-3LP40-3KA2 support?
The MP 370 supports PROFIBUS DP and MPI communication interfaces, as well as RS-422/485 serial communication, allowing direct connection to SIMATIC S7-300 and S7-400 PLCs.
Which HMI software is used to configure and program this panel?
The panel is configured using Siemens WinCC flexible engineering software. The compiled project is then transferred to the panel, which runs WinCC flexible Runtime on Windows CE.
What is the display size and type of the 6AV6146-3LP40-3KA2?
This unit features a 15-inch TFT color display with a resistive touch screen interface, supporting 256 colors.
What is the operating voltage for this panel?
The MP 370 operates on a 24 V DC supply voltage, which is standard for SIMATIC HMI panels in industrial cabinet installations.
Can the project memory be expanded on this panel?
Yes, the panel includes a CompactFlash card slot that can be used to expand storage for project data, alarm logs, recipe data, and trend archives.
Troubleshooting
Display remains blank after power on
Measure the 24 V DC supply voltage at the panel's power connector. Check for correct polarity. Inspect the internal fuse if accessible.
Correct any supply voltage issues. If the supply is confirmed good and the display remains blank, the backlight inverter or internal power supply board may require replacement.
HMI fails to establish communication with the S7 PLC
Verify PROFIBUS or MPI cable integrity and connector seating. Check that the bus termination resistors are correctly placed at both ends of the bus. Confirm the PLC station address in the HMI project matches the physical PLC setting.
Replace damaged cables or connectors. Correct the station address in the WinCC flexible project and re-transfer. Ensure only the two physical bus ends are terminated.
Touch screen does not respond or responds inaccurately
Check for physical damage or contamination on the touch surface. Attempt a touch screen recalibration from the panel's Start Center or Control Panel menu.
Clean the touch surface with a soft, dry cloth. Perform touch screen recalibration. If the issue persists, the touch screen overlay may need to be replaced.
Project transfer from PC to panel fails
Check the transfer cable connection between the PC and the panel's serial or PROFIBUS port. Verify that the panel is set to Transfer mode via the Start Center. Confirm the WinCC flexible version compatibility.
Restart the panel in Transfer mode. Use a known-good transfer cable. Ensure the WinCC flexible project version is compatible with the runtime version installed on the panel. Update the panel runtime if necessary.
Panel repeatedly restarts or crashes during operation
Check for supply voltage fluctuations using a multimeter. Review the alarm and event logs on the panel for recurring system events. Check CompactFlash card seating and integrity.
Stabilize the 24 V DC supply with an appropriate power supply unit. Replace a faulty CompactFlash card. If the issue persists, a firmware update or factory reset followed by project re-transfer may be required.
