Device boot-up occurs after turning on the power supply. The I/O LED flashes
orange.
Then the local bus is initialized. This is indicated by flashing red at 10 Hz for
1 ... 2 seconds.
After a trouble-free initialization, the I/O LED is green.
In the event of an error, the I/O LED continues to blink red. Blink codes indicate
detailed error messages. An error is indicated cyclically by up to 3 flashing
sequences.
After elimination of the error, restart the node by turning the power supply of the
device off and on again.
Manual
Version 1.3.0
Meaning
The fieldbus node is operating correctly.
Start of the firmware.
1 ... 2 seconds of rapid flashing indicates
start-up.
Fieldbus coupler/controller hardware
defect
Flashing with approx. 10 Hz indicates the
initialization of the local bus or a local bus
error.
Up to three successive flashing
sequences indicate local bus errors.
There are short intervals between the
sequences.
No data cycle on the local bus.

Solution
Normal operation.
-
Replace the fieldbus coupler/controller.
Note the following flashing sequence.
Evaluate the flashing sequences based
on the following blink code table.
The blinking indicates an error message
comprised of an error code and error
argument.
The fieldbus coupler/controller supply is
off.
