12.2.2 Example of a Diagnostics Message Indicated by a Flashing
Sequence
The example below illustrates the representation of a diagnostics message via a
flashing sequence. The I/O LED indicates a data error on the local bus. The data
error is caused by the removal of an I/O module located at the 6th position of the
bus node.
Initiation of the Start Phase
1. The I/O LED flashes for 1 cycle at about 10 Hz (10 flashes/second).
2. This is followed by a pause of about one second.
Error Code 4: Data Error in the Local Bus
3. The I/O LED flashes for 4 cycles of about 1Hz.
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 flashes for 5 cycles at 1 Hz.
This indicates that a disruption has occurred at the local bus downcircuit of
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 is repeated.
