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.
Message communications can also be used from host computers or the CPU
Unit of the PLC to read and write CompoNet Slave Unit data.
A CompoNet Network is a remote I/O system that consists of the following
elements.
