10 Network Design
10.1 Star Topology
In a star network, all controllers and devices connect to a central network switch.

Illustration 3: Example of Star Topology
10.2 Line Topology
In a line network, the controller connects directly to 1 port of the 1
st
card. The 2
nd
Ethernet port connects to another card, which in
turn connects to another device until all devices are connected.

Illustration 4: 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.

N O T I C E
Each connection adds a delay to the communication with the next device. The maximum number of devices in a line network is
32. Exceeding this number may reduce the reliability of the network.
10.3 Ring Topology
In a ring topology network, the controller connects to the 1
st
card via a network switch. The 2
nd
Ethernet port of the card connects
to another device, which in turn connects to another device until all devices are connected. The final device connects back to the
switch.
The device supports beacon-based ring node configuration.

N O T I C E
The network switch must support loss of line detection.
10.4 Combined Topologies
A single network can include both star and line components.
