9 Network Design
9.1 Star Topology
In a star network, all controllers and devices connect to a central network switch.
Illustration 4: Example of Star Topology
9.2 Line Topology
In a line network, the controller connects directly to 1 port of the 1
st
device. The 2
nd
Ethernet port connects to another device, which
in turn connects to another device until all devices are connected.
Illustration 5: Example of Line Topology
N O T I C E
The device has an integrated switch to allow data to pass through in line topology. The device must be receiving control power
from the soft starter for the switch to operate.
N O T I C E
If the connection between 2 devices is interrupted, the controller cannot communicate with devices after the interruption point.
