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.
9.3 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.

The network switch must support loss of line detection.
9.4 Combined Topologies
A single network can include both star and line components.
