Description
Additional information

The Siemens 6AV6146-1LP00-2KC1 is a Multi Panel MP 377 belonging to the SIMATIC HMI family, designed for high-performance human-machine interface applications. This panel operates as a standalone visualization unit capable of running WinCC flexible runtime software, providing a robust platform for process monitoring and control. It features a 15-inch widescreen TFT display and is part of Siemens' established MP 377 series, which bridges the gap between standard operator panels and full PC-based systems.

The MP 377 15" Touch (6AV6146-1LP00-2KC1) 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 (RJ45), USB ports, and a serial RS-422/RS-485 interface, enabling integration with a wide range of Siemens and third-party controllers. The panel runs on Microsoft Windows CE 5.0 and provides 12 MB of user memory for project data, with an optional CompactFlash card slot for extended storage. Operating voltage is 24 V DC, and the unit carries CE and UL certifications along with an IP65 protection rating on the front face.

The MP 377 is widely deployed in manufacturing automation, process industries, and machine building applications where a large, reliable touchscreen interface is required. It is commonly found in automotive assembly lines, food and beverage processing plants, water treatment facilities, and packaging machinery. Its compatibility with SIMATIC S7 PLCs, compatibility with PROFIBUS and PROFINET networks, and support for WinCC flexible make it a practical choice for complex visualization tasks in demanding industrial environments.

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 ensuring version compatibility.
Event ID: 10001: Communication connection to the PLC has been lost or cannot be established.
Check PROFIBUS or Ethernet cabling and connector integrity. Verify PLC address settings and ensure the PLC is in RUN mode.
Event ID: 20000: System memory is critically low, which may cause runtime instability or project loading failures.
Reduce project size, remove unused images or scripts, or expand storage using a CompactFlash card.
Event ID: 40000: Tag read/write error. The panel cannot access a configured PLC tag.
Verify the tag address in the WinCC flexible project matches the actual PLC data block structure. Check PLC program for address changes.
Event ID: 70010: Backup battery low or missing. Retained data and real-time clock may not be preserved during power loss.
Replace the internal backup battery with the correct Siemens-specified replacement. Follow ESD precautions during replacement.
Event ID: 110000: Touchscreen calibration error. Touch input is misaligned or unresponsive.
Perform a touchscreen recalibration via the Control Panel in Windows CE. If the issue persists, inspect the touchscreen connector internally.
Event ID: 130000: Project runtime has stopped unexpectedly due to a software exception or corrupted project file.
Restart the panel and reload the project. If the fault recurs, re-download a clean project from the engineering station and check for script errors.

Frequently Asked Questions

What software is used to configure and program the MP 377?

The MP 377 is configured using Siemens WinCC flexible engineering software. Projects are created on a PC and downloaded to the panel via Ethernet or USB connection.

Which PLCs are compatible with the Siemens MP 377 (6AV6146-1LP00-2KC1)?

The MP 377 is compatible with SIMATIC S7-200, S7-300, S7-400, and S7-1200 PLCs via PROFIBUS DP or PROFINET/Ethernet. It also supports communication with third-party controllers using standard protocols.

What is the front panel protection rating of this unit?

The front face of the MP 377 carries an IP65 protection rating, making it suitable for panel-mount installations where exposure to dust and water jets is possible.

Can the MP 377 display be used as a touch-only interface or does it support function keys?

The 6AV6146-1LP00-2KC1 variant is a touch-only panel without dedicated hardware function keys. All operator input is handled via the resistive touchscreen.

What operating system does the MP 377 run?

The MP 377 runs Microsoft Windows CE 5.0, which provides the runtime environment for WinCC flexible and supports the panel's communication and visualization functions.

Troubleshooting

Display remains blank after power is applied

Measure the 24 V DC supply voltage at the panel's power connector. Check that polarity is correct and voltage is within the 19.2–28.8 V DC tolerance range. Inspect the internal fuse if accessible.

Correct any supply voltage issues. If voltage is confirmed correct and the display remains blank, the backlight inverter or internal power supply board may require replacement.

Touchscreen does not respond or registers incorrect touch positions

Attempt a touchscreen recalibration from the Windows CE Control Panel. Check for physical damage, contamination, or delamination of the touch overlay.

Recalibrate the touchscreen using the built-in calibration utility. If calibration fails or touch remains inaccurate, the resistive touch panel assembly may need to be replaced.

Panel cannot establish communication with the PLC over PROFIBUS

Verify the PROFIBUS cable termination resistors are correctly set at both ends of the bus. Check the panel's PROFIBUS address in the WinCC flexible project against the physical address switch or software setting.

Correct bus termination, ensure unique node addresses, and verify cable integrity. Replace the PROFIBUS cable or connector if signal quality is poor.

Project fails to load or runtime crashes on startup

Check the CompactFlash card for corruption using a PC card reader. Verify the WinCC flexible runtime version installed on the panel matches the project version.

Reformat the CompactFlash card and re-download the project from the engineering station. Update the panel firmware if a version mismatch is identified.

Real-time clock resets to default date and time after each power cycle

This indicates the internal backup battery is discharged or missing. The battery maintains the RTC and retained memory during power-off periods.

Replace the internal lithium backup battery with the Siemens-specified type. Observe ESD precautions and reset the clock after battery replacement.
