€ 3.495,00
The Siemens 6AV6146-6QQ40-0LY5 is an industrial panel PC belonging to the SIMATIC IPC677D series, manufactured by Siemens. It is a high-performance, fanless or fan-cooled industrial PC designed for demanding HMI and SCADA applications in harsh industrial environments. The unit integrates a large-format widescreen display with a powerful computing platform into a single panel-mount enclosure.
The SIMATIC IPC677D features a 19-inch or larger widescreen TFT display with multi-touch or resistive touch capability, depending on the variant. It is powered by an Intel Core processor (Celeron, Core i5, or Core i7 depending on configuration) and supports Windows 7 or Windows 10 operating systems. The unit provides multiple communication interfaces including USB 3.0, Gigabit Ethernet (RJ45), and optional PROFINET or PROFIBUS interfaces. It is built to IEC 61131-2 standards for industrial environments and carries CE and UL certifications. The robust aluminum front panel achieves IP65 protection rating when properly panel-mounted.
The SIMATIC IPC677D is widely deployed in the automotive, food and beverage, pharmaceutical, and chemical processing industries. It is particularly suited for use as a central HMI station on large machine lines, SCADA visualization workstations, and process control panels where high computational performance and a large display area are required. Its industrial-grade construction and wide operating temperature range make it reliable in environments with vibration, dust, and temperature fluctuations.

Common Error Codes & System Events
- Event ID: 100
- System startup failure — the operating system failed to boot correctly, possibly due to a corrupted OS image or failed storage device.
Check the CFast card or SSD for errors. Re-image the operating system if necessary. Verify all internal connectors are seated properly. - Event ID: 1001
- Application crash or unexpected software termination detected by Windows Error Reporting.
Review Windows Event Viewer logs for the faulting application. Update or reinstall the affected software. Check for memory errors using Windows Memory Diagnostic. - Thermal Warning
- Internal temperature has exceeded the warning threshold, risking thermal shutdown.
Check that ventilation slots are unobstructed. Verify fan operation if fan-cooled variant. Ensure ambient temperature is within the specified 0–50 °C range. - Watchdog Timeout
- The hardware watchdog timer has triggered a system reset due to an unresponsive application or OS hang.
Investigate the application causing the hang. Check watchdog configuration in BIOS/UEFI settings. Update drivers and OS patches. - Storage Device Error
- The CFast card or SSD is reporting read/write errors or is not detected by the system.
Replace the CFast card or SSD. Re-image the operating system. Ensure the storage device is correctly seated in its slot. - Network Interface Error
- One or both Ethernet interfaces are not detected or are reporting link failures.
Check Ethernet cable connections and switch port status. Update network adapter drivers. Inspect the RJ45 connector for physical damage. - Power Supply Fault
- Input voltage is out of the specified 24 V DC range, causing unstable operation or failure to power on.
Measure the 24 V DC supply at the power input connector. Ensure the supply is within tolerance. Check wiring and fuse on the supply circuit.
Frequently Asked Questions
What is the input voltage for the SIMATIC IPC677D (6AV6146-6QQ40-0LY5)?
The unit operates on 24 V DC. Ensure the power supply is within the specified tolerance range to avoid instability or damage.
What operating systems are supported by this panel PC?
The SIMATIC IPC677D supports Windows 7 (64-bit) and Windows 10 (64-bit), depending on the firmware and hardware variant ordered.
What is the front panel protection rating of this unit?
The front panel achieves IP65 protection when correctly installed in a panel cutout with the supplied gasket, making it suitable for environments with dust and water spray.
Can this panel PC run Siemens WinCC or SCADA software?
Yes, the SIMATIC IPC677D is fully compatible with Siemens WinCC, WinCC flexible, and other SIMATIC HMI software packages, as well as third-party SCADA applications.
Is the storage medium on this unit replaceable in the field?
Yes, the CFast card or SSD used as the primary storage device is designed to be replaceable. A replacement card must be re-imaged with the appropriate operating system and application software.
Troubleshooting
Display remains blank after power is applied
Check the 24 V DC supply voltage at the power input connector. Verify the power LED status. Attempt to connect an external monitor via DisplayPort to determine if the issue is with the display or the system board.
If the external monitor shows output, the internal display or its cable may be faulty — inspect and reseat the display cable. If no output is present on either display, the power supply board or main board may require replacement.
Touchscreen does not respond to input
Check if the touch controller is recognized in Windows Device Manager. Determine whether the issue is hardware (touch overlay) or driver-related by testing with a USB mouse.
Recalibrate the touchscreen using the Windows calibration tool. If unresponsive, update or reinstall the touch driver. If the hardware is physically damaged, the touch overlay panel must be replaced.
System powers on but fails to boot into Windows
Listen for POST beep codes and check BIOS/UEFI for storage device detection. Attempt to boot from an external USB drive to isolate whether the issue is with the OS image or the hardware.
Re-image the CFast card or SSD with a valid OS image. If the storage device is not detected, replace it. Verify that BIOS settings are correctly configured for the boot device.
Unit shuts down unexpectedly during operation
Check the Windows Event Viewer for thermal or power-related events. Measure the 24 V DC supply under load to check for voltage drops. Inspect ventilation and ambient temperature.
Ensure the power supply has sufficient current capacity. Clean ventilation slots and verify fan operation on fan-cooled variants. If thermal shutdown is confirmed, reduce ambient temperature or improve panel ventilation.
Ethernet communication is intermittent or not working
Check the link LEDs on the RJ45 ports. Test with a known-good cable and switch port. Verify network adapter status in Windows Device Manager.
Replace the Ethernet cable if damaged. Update the network adapter driver. If the port is physically damaged, the unit may require board-level repair or replacement of the network interface module.
