Configuring topology and ports
Interconnecting ports
Prerequisite for IRT is the topology configuration with the specification of which device is
connected via which port to which other devices.
There are two options for defining the properties of the cables between the ports of the switches:
● Via the topology view
● Via the object properties
Using the topology view
With the topology view you have an overview of all ports in the project and can interconnect
them centrally.
To configure the topology, proceed as follows:
1. Click the "Topology view" tab.
You can perform the following in the topology view:
– Interconnect ports
– Modify the properties of the interconnection
– Insert passive components
– Arrange for an offline/online comparison to be displayed in online mode
2. If you hover the mouse over the ports, port names are displayed in the tooltip. In the
Inspector window, the properties for each selected port/device are displayed.
3. Click the source port and drag the connection onto the target port.
The topology view then shows the connection between the two ports.

Description
Name of the sync domain. This name is converted automatically if it does not
conform with the DNS conventions.
Here, you can see a list of the IO devices of the sync domain. You can select the
following parameters for the nodes:
● RT class: Select either RT (Real Time) or IRT (Isochronous Real Time).
● Synchronization role: Select sync master or sync slave. The synchronization
role is displayed as "unsynchronized" by default, e.g. for devices in RT net‐
works.
Select the send clock for the sync domain here.
The nodes of the PROFINET IO system are listed here.
