P-NET Ring Topology:

P-NET ring topology is the traditional way of installing P-NET.

The P-NET cable is connected to a number of devices in a way that forms a physical ring.

Each device on the ring is connected using the same principle.

Devices on the P-NET ring can be connected or disconnected during operation without any disturbance of communication between the remaining devices.

A bus segment can have a maximum length of 1200 metres and can contain up to 125 devices.

BM 010 base modules used in ring topology must always be configured for loop through.
