Constructing Networks with Repeater Units

Section 3-4

Wire

Optical fiber cable

:Controller Link Unit/Support Board

:Wire-to-wire Repeater Unit

:Wire-to-optical Repeater Unit (two Units used in a pair)

: Range of a single segment

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

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

Stage 1

CS1W-RPT01 Repeater Unit

Not more than 2 Repeater Units (2 stages) must be passed for any node to reach any other node
