Startup error codes and LED flash sequences on IO cards:
The IO card status LED will be lit (red) during card initialization and self-test (constant red for 3-15 seconds).
If the initialization and self-test are successful, the LED will be dark, and stays dark during normal operation.
If initialization or self-test fails, the LED will flash quickly, indicating the type of error that occurred.
The error code can be used to diagnose the problem further.
The flash sequence is repeated 3 times (3 sequences of N flashes).
Depending on the nature of the error, the system may then reset the card and retry initialization.
Number of flashes | Error type | Comment |
1 | Card load error | Defect card |
2 | Register bus failure | Defect card |
3 | Self-test fail | Defect card |
4 | Card Information invalid | Defect or incompatible card inserted |
6 | Internal initialization fail | Defect card or system |
8 | License error | System is not licensed for the number of I/O cards |
