Example for a fault message; Fault: The 13th I/O module has been removed
1. The "I/O" LED starts the fault display with the first blink sequence (approx. 10
flashes/second).
2. The second blink sequence (1 flash/second) follows the first pause. The "I/O" LED
blinks four times and thus signals the fault code 4 (internal bus data fault).
3. The third blink sequence follows the second pause. The "I/O " LED blinks twelve
times. The fault argument 12 means that the internal bus is interrupted after the 12th
I/O module.
