2.Set the baud rate: When setting the baud rate, take into
account the length of the network lines (main bus line,
branch lines and branches) see subsequent note.

Maximum effective data rate (baud rate)
The setting of the baud rate depends on the length of
all network lines.
• Consider the length of the fieldbus line between the
PLC and bus node (main bus line) as well as the
length of possibly available branch lines and
branches (for continued fieldbus configuration).
• Also consider the overall length (sum) of all branch
lines.
• The subsequent table supplies reference values for
the maximum baud rate, dependent on the line
lengths.
The baud rates named here are not supported by all
controllers.
• Observe possibly deviating specifications in the
manual of your control system or network scanner.
Further information can be found in the specifica-
tions of the ODVA www.odva.org.

Functional test:
– The LED MNS flashes green or is lit green
(if configured via the network, i.e. in case of correct
communication with the PLC chap. 6).
– Die LED IO is off, flashes green or is lit green
(if configures via the network).
5.3 Mounting of the DIL switch cover
1.Place the cover carefully on the bus node. Make sure
that the seal is seated correctly!
2.Tighten the two mounting screws at first hand-tight and
then with max. torque 0.4 Nm.

LED Status and significance
display
LED illuminated green:
– Normal operating status
– Operating voltage applied (in the approved range)
– Load voltage present (in the approved range)
LED flashes green (flashing frequency: 1 Hz)
– Operating voltage is below the required voltage
– Load voltage is below the required voltage
1)
– Short circuit at the I-port
LED is off:
– Operating voltage not applied

LED Status and significance
display
LED illuminated green:
– Normal operating status
– Device is correctly connected to the bus node
– Operating and load voltage present
2)
(in the approved range)
LED flashes green:
– Connected device reports diagnostics status
– Undervoltage at system or additional power supply
– Connection between bus node and device is OK
LED illuminated red:
– Device is connected correctly to the bus node,
but internal communication is faulty
– After commissioning, incorrect device connected
Note
(non-I-port-compatible device recognised)
– Device was removed after initialization of the bus
node
LED flashes red:
– During commissioning, incorrect device connected
(non-I-port-compatible device recognised)
– If only LED X1 flashes red: error in the bus node
– If X1 and X2 flash red simultaneously: no device
connected to the bus node (at least one device is
required)
LED is off:
– No device is connected to the bus node

MNS – Module status/network status
(combined module/network status)
LED Status and significance
display
LED illuminated green:
– Normal operating status ("online")
– Communication with the fieldbus is OK
LED flashes green:
– Fieldbus communication available ("online"),
but not configured
LED illuminated red:
– No fieldbus communication
(not available, failed or invalid bus address)
– No power supply to bus chap. 4
LED flashes red:
– Communications error (fieldbus communication
faulty, bus time-out or no power supply to bus
chap. 4)
LED is off:
– No network or fieldbus connection (not "online",
MAC-ID test "DUB_MAC_ID" did not run successfully
or no power supply to bus chap. 4)
IO= I/O status, connection status
LED Status and significance
display
LED illuminated green:
– Normal operating status, communication with the
controller (PLC) OK
– IOs are controlled through the fieldbus
LED flashes green:
– Operating status in preparation
– IOs are in the idle status
LED illuminated red:
– Inputs/outputs are in the fail-state mode; cause is an
unrecoverable fault (e.g. no bus voltage)
LED flashes red:
– Failure or stop of PLC, fieldbus interruption or
telegram failure
– IOs are in the fail-state status
– Incorrect station number in the PLC or bus node
(incorrect DIL-switch position)
LED is off:
– Commissioning of the bus node not complete or not
successful
