Description
Additional information

The Siemens 6AV7612-0AA20-0AH0 is a Panel PC belonging to the SIMATIC Panel PC 670 series, manufactured by Siemens. It is an industrial panel-mounted PC designed for demanding human-machine interface (HMI) and visualization tasks in automation environments. This unit combines a flat-panel display with an integrated PC platform, offering a compact and robust solution for process visualization and control.

The SIMATIC Panel PC 670 (6AV7612-0AA20-0AH0) features a 12-inch TFT display with a resolution of 800 x 600 pixels (SVGA) and supports touch screen operation. It is equipped with an industrial-grade processor and runs on Microsoft Windows operating systems, supporting SIMATIC WinCC and other Siemens HMI software packages. The unit provides standard PC interfaces including USB, serial (COM), and Ethernet ports, enabling integration with SIMATIC S7 PLCs and other automation systems via PROFIBUS or Industrial Ethernet. The fanless or low-noise design and the use of industrial-grade components ensure reliable long-term operation in harsh industrial environments.

The SIMATIC Panel PC 670 is widely used in manufacturing, process industries, automotive production, and machine building applications where a full PC-based HMI platform is required. Its compatibility with standard PC software and Siemens SIMATIC software makes it suitable for complex visualization, data logging, and recipe management tasks. The panel-mount form factor allows direct integration into control cabinets and operator panels on the factory floor.

Common Error Codes & System Events

Event ID: 100: System startup error — the operating system failed to initialize correctly during boot.
Check the hard disk or CompactFlash card for integrity. Verify the OS installation and restart the device. Replace storage media if corrupted.
Event ID: 200: Hardware watchdog timeout — the system watchdog has detected that the application stopped responding.
Restart the Panel PC. Check the running HMI application for software errors or infinite loops. Update or reinstall the HMI software if the issue persists.
Event ID: 300: Communication connection lost — the HMI application has lost communication with the connected PLC or controller.
Check Ethernet or PROFIBUS cabling and connections. Verify PLC is powered and running. Check IP address configuration and network settings in WinCC or the HMI project.
Event ID: 400: Touchscreen calibration error — the touch input is misaligned or not responding correctly.
Run the touchscreen calibration utility from the Windows Control Panel or SIMATIC HMI settings. If calibration fails, check the touch controller hardware and connections internally.
Event ID: 500: Power supply undervoltage — the 24 V DC supply voltage has dropped below the permissible operating range.
Measure the supply voltage at the power connector. Ensure the power supply unit provides a stable 24 V DC within the specified tolerance. Replace or adjust the power supply as needed.
Event ID: 600: Storage media error — read/write error detected on the hard disk or CompactFlash card.
Back up data immediately if possible. Run a disk check utility. Replace the hard disk or CompactFlash card if errors persist, and restore the OS and HMI project from backup.
Event ID: 700: Fan failure warning — the system cooling fan has stopped or is running below the required speed.
Check the fan for obstruction or mechanical failure. Clean or replace the fan unit. Ensure ambient temperature is within the specified operating range.

Frequently Asked Questions

What operating systems are supported by the SIMATIC Panel PC 670 (6AV7612-0AA20-0AH0)?

The SIMATIC Panel PC 670 supports Microsoft Windows XP Professional and Windows 2000, which are pre-installed depending on the variant ordered. It is compatible with SIMATIC WinCC and other Siemens HMI visualization software.

What is the supply voltage for the 6AV7612-0AA20-0AH0?

What communication interfaces are available on this Panel PC?

The 6AV7612-0AA20-0AH0 provides Ethernet (RJ45), USB ports, and RS-232 serial (COM) interfaces, enabling connectivity to SIMATIC S7 PLCs via Industrial Ethernet or serial communication.

What is the display size and resolution of the 6AV7612-0AA20-0AH0?

This unit features a 12-inch TFT color display with a resolution of 800 x 600 pixels (SVGA) and resistive touch screen input.

What is the IP protection rating of the front panel?

The front panel of the SIMATIC Panel PC 670 carries an IP65 protection rating, making it resistant to dust and water jets, suitable for installation in industrial environments.

Troubleshooting

Display remains blank after power on

Check that 24 V DC is present at the power supply connector. Verify the display backlight is functioning by looking for a faint image on the screen in a dark environment.

If supply voltage is correct but display is blank, the backlight inverter or the TFT panel may have failed. Replace the backlight unit or the display assembly. If no voltage is present, check the power supply and wiring.

Touchscreen does not respond or responds inaccurately

Attempt to operate the system using a USB mouse to determine if the issue is isolated to the touch controller. Check Device Manager in Windows for touch controller errors.

Run the touchscreen calibration utility. If calibration does not resolve the issue, check internal ribbon cable connections to the touch controller. Replace the touch screen overlay or controller board if faulty.

Panel PC fails to boot or continuously restarts

Check for error messages during POST (Power-On Self-Test). Connect an external monitor via the VGA port if available to observe boot messages. Check the hard disk or CompactFlash card for errors.

Run a disk check utility from a bootable USB or recovery media. If the storage media is corrupted, replace it and reinstall the operating system and HMI software from backup media.

Loss of communication with PLC

Verify the Ethernet cable connection and check the link LED on the RJ45 port. Ping the PLC IP address from the Panel PC to test network connectivity. Check the WinCC or HMI project communication settings.

Correct any IP address mismatches or subnet configuration errors. Replace the Ethernet cable if damaged. If the network adapter is faulty, check Device Manager and update or reinstall the network driver, or replace the network interface card.

System clock resets to incorrect date and time after power off

This typically indicates that the internal CMOS battery on the motherboard has discharged or failed.

Replace the internal CMOS battery (typically a CR2032 coin cell) on the Panel PC motherboard. After replacement, set the correct date and time in the BIOS and Windows settings.
