Example of an Error Message via Blink Code

The following example explains the representation of an error message via blink
code. A data error is displayed on the internal data bus caused by the removal of
an I/O module located in the 6th position of the I/O-IPC.
Initiation of the Start Phase
1. The I/O LED begins with the initiation of the start phase: one cycle of about
10 Hz (10 blinks/second).
2. This is followed by a pause of about one second.
Error Code 4: Data Error in the Internal Data Bus
3. The I/O-LED blinks 4 cycles of about 1 Hz.
4. This is followed by a pause of about 1 second.
Error Argument 5: I/O Module at the 6th Slot
5. The I/O-LED blinks 5 cycles of 1 Hz.
This means that an interruption has occurred on the internal data bus after
the 5th I/O module.
6. The blink code starts flickering when the start phase is initiated again. If
there is only one error, this process repeats.
