What are the topological connection modes between the master station modules of Balluff's PROFINET?

Balluff's IO-Link product types

There are mainly the following topologies:

1.) Backbone branch network connection

■ troubleshooting is very simple

■ can disconnect a single device without interrupting the network

■ additional cables are required, resulting in increased costs

2.) Serial network connection

■ trouble shooting and troubleshooting

■ disconnecting a device will interrupt the network

■ fewer cable laying components and lower cost

3.) Star type

■ easy troubleshooting

■ suitable for a large number of I / O points

■ lower cost - only one switch is required

4.) Hybrid topology

■ create logical groups to make troubleshooting relatively simple

■ the most common way - ideal cost/ benefit ratio
