Color Significance
green LNK/ACT LEDs provide information on each port connection to the
PROFINET IO network and identify the station via MAC address (2
Hz blink frequency when I/O supervisor requests the participant blink
green
test).
red The BF LED shows information on the condition of the data
exchange between the buscoupler and the I/O controller.
red The DIA LED shows parameter setting faults and external
diagnostics.
BF DIA Significance
Off Off The buscoupler is not provided
with its required operating
voltage or a hardware fault is
present.
On * The operating voltage for the
buscoupler is present. The
physical connection to the
PROFINET IO is not
established.
blinks * A physical connection is not
established between the
buscoupler and I/O controller.
blinks * The physical network connection
to the I/O controller is
established. However, data
exchange could not be carried
out.
Offs * The buscoupler is performing a
productive data exchange with
the I/O controller. Configuration
and parameter setting has been
taken over by the buscoupler.
* On The buscoupler reports a
diagnostics information which is
still present.
Remedy
Check the voltage supply to the
bus coupler. Replace the
buscoupler if necessary.
Make sure that the RJ-45 socket is
connected to the switch using a
CAT 5 Ethernet cable.
Establish a connection between the
buscoupler and I/O controller via
the network.
Check the device names that have
been allocated to the device.
Check the configuration of I/O
device.
The data exchange works trouble
free. A diagnostic information
such as cable break on an analog
input module is active.
