The CompoNet Master Unit controls the CompoNet network and transfers data
to and from all Slave Units.
The CompoNet Master Unit can send explicit messages to the CompoNet
Communication Unit.
The CompoNet Communications Unit is the interface with the CompoNet net-
work. You connect it to the CompoNet Master Unit. You connect each Compo-
Net Communications Unit to SmartSlice I/O Units with the number of I/O points
which is necessary in each location. The CompoNet Communications Unit
does communications with the SmartSlice I/O Units.
The CompoNet Communications Unit temporarily keeps the I/O data from the
SmartSlice I/O Units which are connected to it. I/O data is transferred to and
from the CompoNet Master Unit all at one time during remote I/O communica-
tions.
The SmartSlice I/O Units do communications with the CompoNet Master Unit
through the CompoNet Communications Unit.
You can normally connect a maximum of 64 SmartSlice I/O Units to one Com-
poNet Communications Unit. There are restrictions in the number of Smart-
Slice I/O Units if the total data size is too large or power supply capacity is too
small.
You use a Turnback Unit to expand or divide a SmartSlice I/O Terminal.
You use a Turnback Cable to connect a Left Turnback Unit to a Right Turnback
Unit.
You connect an End Unit to the end of the SmartSlice I/O Terminal.
You use the CX-Integrator to write the parameters in the CompoNet Communi-
cations Unit and SmartSlice I/O Units and to monitor these parameters.
The CX-Integrator runs on a Windows computer.
