Constructing Networks with Repeater Units
Section 3-4
The path from one node to another travels via three Repeater Units
(3 stages). This kind of network is NOT allowed.
Note
If the Repeater Units are used incorrectly, communications errors may occur,
or nodes may not be able to participate in the network.
3-4-3
Terminating Resistance
In a Wired Controller Link Network, turn ON the terminating resistance
switches only at the nodes at both ends of the network.
When Repeater Units are used to divide the network into multiple segments,
turn ON the terminating resistance switches of the nodes at both ends of each
segment. When a Repeater Unit is connected to the end of a segment, turn
ON the built-in terminating resistance switch of the Repeater Unit itself.
Connection examples are shown below.
