3.9.1 Introduction
Topology of the PROFINET devices
The "Topology" web page provides information on the topological configuration and status of
the PROFINET devices on your PROFINET IO system.
There are three tabs for the following views:
● Graphical view (set and actual topology)
● Table view (actual topology only)
● Status overview (excluding topological correlations)
You can print the table view and status overview. Before printing, use the print preview of
your browser and, if necessary, correct the format.
Set topology
The set topology is displayed if you have topologically interconnected the connections in the
configuration with STEP 7.
This view identifies the topological assignment of PROFINET devices that have failed, the
differences between the set and actual topology, and interchanged ports.
Note
The configured set topology is always displayed by default in the following scenarios:
• When the "Topology" web page is called via the navigation bar
• When you change from the overview of PROFINET IO devices on the "Module
information" web page to the "Topology" web page by means of the "Topology" link.
If a setpoint topology was not configured, the actual topology is displayed.
Actual topology
Displays the current topological structure of the "configured" PROFINET devices of a
PROFINET IO system and the directly adjacent, non-configured PROFINET devices (display
of the neighbor relationships, provided these can be determined; but the status of these
adjacent PROFINET devices is not displayed).
