Overall System Configuration and Elements
A CompoNet Network is a remote I/O system that consists of the following
elements.
System Configuration Example
Communications Cables
CompoNet Networks use round cable I, round cable II, Flat Cable I (DCA4-
4F10 Standard Flat Cable), and Flat Cable II (DCA5-4F10 Sheathed Flat
Cable) for Communications Cables.
Master Unit
The Master Unit manages the CompoNet Network and transfers I/O data
between the PLC and the Slave Units.
There is only one Master Unit per network. The Master Unit must be con-
nected to the trunk line.
