Description
Additional information

The Siemens 6AV6146-1LP01-2KA1 is a Multi Panel (MP 377) belonging to the SIMATIC HMI family, designed as a high-performance operator panel for industrial human-machine interface applications. This unit features a 15-inch widescreen TFT display and is part of the MP 377 series, which represents Siemens' advanced panel PC and multi-panel lineup for demanding visualization tasks. It operates as a standalone HMI device capable of running WinCC flexible runtime environments for process visualization and control.

The MP 377 15" Touch (6AV6146-1LP01-2KA1) is equipped with a resistive touchscreen interface and delivers a display resolution of 1024 x 768 pixels with 64,000 colors. It includes multiple communication interfaces such as PROFIBUS DP, PROFINET/Ethernet, USB ports, and a CF card slot for expanded memory and data logging. The panel supports MPI/PROFIBUS DP connectivity for direct integration with Siemens S7 PLCs and runs on a 24 V DC power supply. Onboard memory includes 12 MB user memory for project data, and the unit is built to withstand industrial environments with a front panel protection rating of IP65.

The MP 377 is widely deployed in manufacturing, process automation, and machine building industries where large-format, touch-based operator interfaces are required. It is commonly found on packaging machinery, press lines, conveyor systems, and process plant control stations where operators need clear visualization of process data and intuitive touch-based control. Its compatibility with the full range of Siemens S7-300, S7-400, and S7-1200 PLC families makes it a versatile choice for both new installations and system upgrades.

Common Error Codes & System Events

Event ID: 10000: Configuration error detected during project download or startup. The project file may be incompatible with the panel firmware version.
Verify that the WinCC flexible project version matches the panel firmware. Re-download the project after updating firmware if necessary.
Event ID: 10001: Communication connection to the PLC has been interrupted or cannot be established.
Check PROFIBUS/MPI or Ethernet cable connections, verify PLC address settings, and confirm the communication driver configuration in the WinCC flexible project.
Event ID: 20000: Insufficient memory available for project execution. The project may exceed the available user memory.
Reduce project size by optimizing graphics, removing unused tags, or archiving data. Consider using a CF card for extended storage.
Event ID: 40000: Backup battery low or battery failure detected. Retained data and real-time clock may be lost on power failure.
Replace the internal backup battery with the correct Siemens-specified replacement battery and reset the real-time clock after replacement.
Event ID: 50000: Touchscreen calibration error or touch input not responding correctly.
Perform a touchscreen recalibration via the Control Panel in the Start menu of the panel operating system. Clean the screen surface and check for physical damage.
Event ID: 60000: CF card read/write error or CF card not recognized.
Remove and reinsert the CF card. Verify the card is formatted correctly (FAT32). Replace the CF card if errors persist.
Event ID: 70000: Firmware update failed or firmware version mismatch detected.
Re-initiate the firmware update using ProSave or WinCC flexible. Ensure the correct firmware version for the MP 377 15" is used and that power is stable during the update process.

Frequently Asked Questions

What PLC families are compatible with the MP 377 6AV6146-1LP01-2KA1?

The MP 377 is compatible with Siemens S7-300, S7-400, S7-1200, and S7-1500 PLC families via MPI, PROFIBUS DP, or PROFINET/Ethernet interfaces. It can also communicate with third-party controllers using supported drivers in WinCC flexible.

What software is required to program or configure this panel?

The MP 377 is configured using Siemens WinCC flexible 2008 or later. Projects are downloaded to the panel via Ethernet, USB, or CF card using the ProSave utility or directly from WinCC flexible.

What is the display size and touch technology used on this panel?

The 6AV6146-1LP01-2KA1 features a 15-inch TFT LCD display with a resistive touchscreen, providing a resolution of 1024 x 768 pixels and 64,000 colors.

What is the front panel protection rating of the MP 377?

The front panel of the MP 377 carries an IP65 protection rating, making it suitable for installation in environments where dust and water jets may be present.

Can the MP 377 be used with a CF card for data logging or project storage?

Yes, the MP 377 includes a CF card slot that supports CompactFlash cards for extended data logging, recipe storage, and project backup. The card should be formatted to FAT32 for compatibility.

Troubleshooting

Display remains blank after power is applied

Measure the 24 V DC supply voltage at the panel power connector. Check that voltage is within the 19.2 V to 28.8 V range. Inspect the internal fuse if accessible.

Correct the supply voltage if out of range. If voltage is correct and display remains blank, the internal power supply board or backlight inverter may be faulty and require replacement or professional repair.

Touchscreen does not respond or registers incorrect touch positions

Attempt to interact with the panel using a stylus to isolate whether the issue is with finger touch sensitivity or full touch failure. Check for physical damage or contamination on the screen surface.

Perform a touchscreen recalibration through the panel Control Panel. Clean the screen with a soft, dry cloth. If calibration fails repeatedly, the touchscreen overlay may need replacement.

Panel fails to communicate with the connected PLC

Verify the communication cable connections on both the panel and PLC side. Check the configured PLC address and communication protocol in the WinCC flexible project against the actual PLC settings.

Correct any address mismatches in the project configuration. Replace the communication cable if damaged. Ensure the correct communication driver is installed and active on the panel.

Project download fails or panel does not accept new project

Check the firmware version on the panel using the Start Center or Control Panel. Compare it against the WinCC flexible version used to create the project. Verify the download connection (USB or Ethernet) is stable.

Update the panel firmware to a version compatible with the WinCC flexible project using ProSave. Re-attempt the download after firmware update. Ensure no other software is interfering with the USB or network connection.

Panel reboots unexpectedly or freezes during operation

Check the supply voltage for fluctuations or drops below 19.2 V DC under load. Review the system event log on the panel for recorded fault events prior to the reboot.

Stabilize the power supply by using a dedicated 24 V DC source with adequate current capacity. If the issue persists, check for overheating by verifying ambient temperature is within the 0 °C to 50 °C operating range and that ventilation around the panel is adequate.
