Evaluating the Fieldbus Status

The top three LEDs (RUN, BF and DIA) are used to indicate the operating status
of PROFINET IO communication.

Explanation
The power supply is ON.
Part of or the entire fieldbus node
is in energy-saving mode or output
mode due to the PROFIenergy
"Start Pause" command.
The power supply is OFF.
1 Hz, pulse-no-pulse ratio 1:1 (for
3 sec.):
Node flashing test (DCP Control
Signal FlashOnce).
With repetitive node flashing tests
in succession, the indicator light
can briefly capture the status of the
group fault display (red).
There is no ETHERNET
connection (link).
There is an ETHERNET
connection on at least one port. A
PROFINET connection (IOAR) is
not established.
At lease on application relationship
has been established to an IO
controller (IOAR).
Parameterization error, module
differences or diagnostics display.
Evaluating the diagnostics display!
A detailed description of the diagnostics display analysis is
available in the chapter "PROFINET IO Diagnostics"!
Solution
-
1. Use the PROFIenergy "End Pause"
command to exit energy-saving
modes.
1. Check the power supply
(24 V, 0 V).
-
1. Check the network cable.
1. Check the connection between IO
controller and IO device.
2. Check if the right device name has
been assigned for the IO device.
3. Check if the connected network
infrastructure ETHERNET link is
100 Mbit/s full-duplex compliant.
-
1. Check the parameter settings and
fieldbus node setup or evaluate the
diagnostics display.
