A CompoNet Network is a remote I/O system that consists of the following elements.
Segment
■ Segment layers
When Repeater Units are used, the CompoNet Network is divided into segments by the Repeater Units.
Each segment is connected to the network, but is isolated electrically.
Three layers of these isolated segments can be configured, 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).
■ Number of Units Per Segment
A maximum of 32 Slave Units and Repeater Units can be connected in the same segment.

Trunk Lines and Branch Lines
The trunk lines and branch lines are defined as follows:
·
·
·
·
Trunk line: The transmission path between the Master
Unit and the terminating resistance.
Sub-trunk line: The transmission path between the
Repeater Unit and the terminating resistance.
Branch line: The transmission path created using a
T-branch from the trunk line or sub-trunk line.
Sub-branch line: The transmission path created using a
T-branch from a branch line. (T-branching is not possible
from sub-branch lines.)
cable must be used between the trunk line and a
branch line, a sub-trunk line and branch line, and a
branch line and sub-branch line. Different types of
cable can be used between the trunk line and a sub-
trunk line.
