Self-Diagnosis and Error Codes

The SENSORswitch includes the following diagnosis features:

  • Self-Test: When triggered by the respective IO-Link System Command:
    • The capacitive measurement circuit is checked (duration: 200 ms)
    • The RGB LED is checked electrically
  • Monitoring of Supply Voltage and MCU Temperature
  • Output Overload Detection

Detected errors are indicated via IO-Link Events and/or in the Error Code IO-Link Parameter, as well as by blinking patterns of the LED.
