LED Color Significance
LINK green The "LINK" LED indicates that a
physical connection to the Ethernet
network is established. It flashes with a
frequency of 2 Hz for a period of 3
seconds when the fieldbus coupler is
requested to the participant flash test by
the DCP protocol (Discovery and basic
Configuration Protocol).
BF red The "BF" LED provides information on
the current status of the PROFINET IO
data exchange.
DIA red The "DIA" LED indicates the upcoming
of diagnostics events. The message
from the diagnostics is not supported by
all I/O modules or must be explicitly
released for each channel.
TxD/ green The "TxD/RxD" LED indicates the
RxD communication that is taking place over
the Ethernet.
I/O red /green / The "I/O" LED indicates both the
orange internal bus communication and
occurring errors.
A green Status of the operating voltage –
system
B green Status of the operating voltage –
power contacts
