Features

CompoNet Networks feature easy operation and installation in a component-level network that con-
nects Controllers and onsite I/O. The CPU Unit and CompoNet Slave Units cyclically exchange I/O
information through the CompoNet Master Unit, refreshing I/O in sync with the task periods of the CPU
Unit. Message communications can also be used from host computers or the Master Unit on the Con-
troller to read and write data for CompoNet Slave Units.
