CompoNet Networks
Section 2-1
1) T-branch Connections
• T-branch connections using Flat Connectors (when Flat Cable I or Flat
Cable II is used)
• T-branch connections using commercially available relay terminals (when
round cable I or round cable II is used)
2) Multidrop Connections
• Multidrop connections using Flat Connectors and Multidrop Connectors
(when Flat Cable I or Flat Cable II is used)
• Multidrop connections using Open Type Connectors (when round cable I
or round cable II is used)
Note
Flat Connectors can also be used to extend the Communications
Cable.
Communications Power
Supply
This is the power supply for communications and internal operations for each
Unit.
A commercially available 24-VDC power supply is used for communications
and internal operations in each Unit.
One communications power supply can be connected for a trunk line or a sub-
trunk line. Communications power is supplied to the trunk line from the Master
Unit and to a sub-trunk line from the Repeater Unit.
One power supply cannot be used to supply communications power to more
than one line (i.e., to the trunk line and sub-trunk line or to two sub-trunk
lines).
I/O Power Supply
A commercially available 24-VDC power supply is used to power the I/O oper-
ations of the external I/O device connected to a Unit. It is connected to the I/O
power supply terminal of the Unit.

Segments
Segment Layers
When Repeater Units are used, the CompoNet Network is divided into seg-
ments by the Repeater Units. Each segment is connected to the network, but
is isolated electrically. Three layers of these isolated segments can be config-
ured, called segments 1, 2, and 3, counted in order from the Master Unit.
Repeater Units can be used to add a maximum of two extra segment layers.
Including Repeater Units connected using multidrop connections, a maximum
of 64 Repeater Units can be connected in a single network (i.e., to a single
Master Unit).
