Siemens 6AV7611-0AA22-0BE0 SIMATIC Panel PC 670

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 Compact Flash card for errors. Verify the OS installation is intact and re-image if necessary.

Event ID: 200

Hardware watchdog timeout — the watchdog timer triggered a system reset due to an application hang.
Identify and terminate the hanging application. Check CPU load and memory usage. Update or reinstall the offending software.

Event ID: 300

Fan failure detected — the internal cooling fan has stopped or is running below the required speed.
Inspect and clean the fan. Replace the fan unit if it is defective to prevent thermal shutdown.

Event ID: 400

Temperature warning — internal temperature has exceeded the defined threshold.
Check ambient temperature and ventilation around the panel. Clean air filters and ensure the fan is operational. Reduce ambient temperature if necessary.

Event ID: 500

Battery low warning — the CMOS/RTC backup battery voltage is below the minimum threshold.
Replace the internal CMOS battery (typically CR2032 or equivalent) to prevent loss of BIOS settings and real-time clock data.

Event ID: 600

Hard disk or storage medium error — read/write errors detected on the internal storage device.
Run a disk diagnostic utility. Back up data immediately and replace the hard disk or Compact Flash card if errors persist.

Event ID: 700

Communication interface error — loss of communication on the Ethernet or serial interface.
Check cable connections and network configuration. Verify IP address settings and communication driver installation in the OS.

Event ID: 800

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 is rated correctly and check for wiring issues or excessive voltage drop.
