Description
Additional information

The Siemens 6AV6146-1RQ01-1LY5 is a Multi Panel belonging to the SIMATIC MP 377 series, part of Siemens' SIMATIC HMI product line. This panel is a high-performance operator interface device designed for demanding industrial visualization and control tasks. It runs the Windows CE operating system and is engineered for use with Siemens WinCC flexible runtime software.

The MP 377 panel features a 15-inch TFT widescreen display with a resolution of 1024 x 768 pixels and 64,000 colors, providing clear and detailed process visualization. It is equipped with a resistive touch screen as well as function keys, offering flexible operator input options. Communication interfaces include PROFIBUS DP, PROFINET (Ethernet), USB ports, and an MPI interface, enabling seamless integration into a wide range of automation architectures. The panel includes 12 MB of user memory for project data and supports CF card slots for extended storage. Its robust industrial-grade housing is rated IP65 on the front face, protecting against dust and water ingress.

The SIMATIC MP 377 is widely deployed in manufacturing, process industries, automotive production, and energy management applications. Its combination of a large display, versatile communication options, and compatibility with Siemens S7-300 and S7-400 PLCs makes it suitable for complex SCADA and HMI applications requiring detailed process overviews. The panel is also used in water treatment, chemical processing, and machine tool environments where reliable long-term operation is essential.

Common Error Codes & System Events

Event ID: 10000: Connection to PLC lost or communication timeout detected between the HMI panel and the configured controller.
Check PROFIBUS/PROFINET cabling and connector integrity. Verify PLC is powered and running. Confirm communication parameters (address, baud rate) match in WinCC flexible project.
Event ID: 10001: Connection to PLC established after a previous communication failure.
Informational event. No corrective action required. Monitor for recurring disconnections which may indicate network instability.
Event ID: 20000: Tag read error — the HMI was unable to read a configured tag from the controller.
Verify the tag address exists in the PLC program and has not been modified. Check that the data block or memory area referenced is accessible and correctly configured in WinCC flexible.
Event ID: 40000: Project download error — a fault occurred during project transfer to the panel.
Ensure the correct transfer channel is selected and the panel is in transfer mode. Check USB or Ethernet cable connection. Verify WinCC flexible version compatibility with the panel firmware.
Event ID: 70010: Backup/restore error — an error occurred during data backup or restore operation via CF card or USB.
Check that the CF card or USB storage device is properly inserted and has sufficient free space. Verify the storage medium is not write-protected or corrupted.
Event ID: 50000: Alarm logging error — the HMI was unable to write alarm records to the configured data storage location.
Check available storage space on the CF card or internal memory. Verify alarm logging configuration in WinCC flexible and ensure the target path is valid and accessible.
Event ID: 60000: Recipe data error — a fault occurred when reading or writing recipe data.
Verify recipe configuration in WinCC flexible. Ensure the target storage medium is available and not full. Check that recipe tag addresses are correctly mapped to the PLC.

Frequently Asked Questions

Which PLC families is the SIMATIC MP 377 compatible with?

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

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

The panel is configured using Siemens WinCC flexible 2008 or later. Projects are created on a PC and transferred to the panel via Ethernet, USB, or MPI/PROFIBUS connection.

What is the input voltage requirement for the 6AV6146-1RQ01-1LY5?

The panel requires a 24 V DC power supply. Ensure the supply is capable of providing sufficient current to meet the panel's maximum power consumption of approximately 60 W.

Can the MP 377 panel be used outdoors?

The MP 377 is rated IP65 on the front face, providing protection against dust and water jets, but it is not designed for direct outdoor exposure to sunlight or extreme weather without additional protective enclosure measures.

What storage expansion options are available on the MP 377?

The MP 377 supports CompactFlash (CF) cards for extended project and data storage, as well as USB ports for connecting USB storage devices or peripherals.

Troubleshooting

Display remains blank after power on

Measure the 24 V DC supply voltage at the power connector. Check that the supply current is sufficient. Inspect the panel for any visible damage to the power input terminals.

Ensure the 24 V DC supply is stable and within tolerance. If the supply is correct and the display remains blank, the internal power supply board or backlight inverter may be faulty and require replacement.

Touch screen does not respond or responds inaccurately

Attempt to operate the panel using the physical function keys to determine if the issue is isolated to the touch screen. Check for physical damage or contamination on the screen surface.

Perform a touch screen recalibration through the panel's Start Center or Control Panel settings. Clean the screen surface with a soft, dry cloth. If recalibration does not resolve the issue, the touch screen overlay may need to be replaced.

Panel cannot establish communication with the PLC

Verify the communication cable connections on both the panel and PLC sides. Check the configured communication parameters (IP address, PROFIBUS address, baud rate) in the WinCC flexible project against the PLC settings.

Correct any mismatched communication parameters and re-download the project. Replace faulty cables or connectors. Ensure the PLC is in RUN mode and that the network is free of address conflicts.

Project transfer fails from engineering PC to panel

Confirm the panel is in Transfer mode via the Start Center. Check the connection type selected in WinCC flexible matches the physical connection being used (USB, Ethernet, or MPI).

Restart the panel into Transfer mode and retry the download. Verify firewall settings on the engineering PC are not blocking the transfer. Ensure WinCC flexible runtime version on the panel is compatible with the project version.

Panel reboots unexpectedly or freezes during operation

Check the 24 V DC supply for voltage drops or instability under load. Review the system event log on the panel for recorded fault events prior to the reboot. Check for overheating by verifying ambient temperature and ventilation around the panel.

Stabilize the power supply and ensure adequate ventilation. If the issue persists, back up the project and perform a factory reset of the panel, then re-download the project. Persistent instability may indicate a hardware fault requiring panel repair or replacement.
