CompoNet Networks feature easy operation and installation in a component-
level network connecting PLCs and on-site I/O. The PLC and CompoNet
Slave Units cyclically exchange I/O information through a CompoNet Master
Unit, refreshing I/O in sync with the PLC scan. CompoNet (just like
DeviceNet) is a member of a family of networks that implements the Common
Industrial Protocol (CIP) at its upper layers.
Two types of communications are supported to provide a single point of con-
nection for both control and configuration:
1. Time-critical control remote I/O communications that automatically transfer
between the Master Unit/CPU Unit and the remote Slave Units, and
2. Explicit message communications that read/write messages, control oper-
ation, or perform other functions to the Slave Units. Message communica-
tions are achieved by executing specific instructions from the program in
the CPU Unit to which the Master Unit is mounted.
CompoNet Slave Units can be classified into the following groups:
Word Slave Units are Slave Units that are allocated units of 16 bits (i.e., 1
word) in I/O memory of the CPU Unit.
Bit Slave Units are Slave Units that are allocated units of 2 bits in I/O memory
of the CPU Unit. Bit Slave Units provide 2 or 4 digital contact I/O points and
have Standard or Sheathed Flat Cable already connected.
Units that can be used to expand the network by extending trunk lines or
branching
