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.
