PROFINET Card
Installation Guide
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.

7.3 Ring Topology

In a ring topology network, the controller connects to the 1
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.
