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 stimulated, producing an "actuation" for 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.
Error Codes
| Blink Code | IO-Link Error Code | Description |
|---|---|---|
| 1 | 0x0001 | Internal error |
| 5 | 0x0010 | Test of capacitive sensor failed |
| 8 | 0x0080 | Memory error |
| 12 | 0x0800 | LED error |
| 13 | 0x1000 | Overload error on digital output |
