Constructing Networks with Repeater Units
Section 3-4
3-4-2
Number of Repeater Units
The number of Repeater Units that can be connected in a Wired Controller
Link Network depends on the mode of connection.
When Repeater Units are used, a maximum of 32 Units, including Controller
Link Units/Support Boards and Repeater Units, can be connected within a
single segment.
Moreover, if Repeater Units are used for T-Branch wiring, long-distance wiring
or partial conversion to optical fiber, up to two repeater stages (see note
below) can be connected. Connect Repeater Units so that they do not exceed
these ranges.
Note
The maximum number of repeater stages refers to the maximum number of
Repeater Units that can be inserted into the path connecting any two nodes.
In other words, it is necessary to connect Repeater Units so that no more than
two Repeater Units (two stages) need to be passed for any node within a net-
work to reach any other node. With Wire-to-Optical Repeater Units, two Units
make up a single set, which is counted as a single stage.
Examples of Correct Repeater Unit Connections
T-Branch Wiring: 2-stage Repeater Unit Connection
Not more than 2 Repeater Units (2 stages) must be passed for any node to
reach any other node

Note:
The Repeater Unit will be
counted in the number of
nodes for each segment that
it is connected to.
