account the length of the network lines (main bus line,
branch lines and branches)

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

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.
