● Graphic view
● Table view
● Status overview (excluding topological correlations)
The views and status overview can be printed. Before printing out, use the print preview of
your browser. If necessary, correct the format.
From the drop-down list in the header bar, select the display mode:
● Display mode "Set topology"
● Display mode "Actual topology"
Display mode "Set topology"
Display of the topological layout configured in the topology editor of STEP 7 with
corresponding status displays. The topological layout contains the configured PROFINET
devices of a PROFINET IO system. The display includes neighboring PROFINET devices,
provided their topological layout is configured as well. There is, however, no status display
for neighboring PROFINET devices.
The view identifies the topological assignment of PROFINET devices that have failed, the
differences between the target and actual topology, and interchanged ports.
Note
Special feature
The configured target topology is always displayed 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 "Topology" link
If no target topology was configured, the actual topology is called by default.
Display mode "Actual topology"
The actual status detected in the PROFINET IO system is displayed. The display is based
on the system configuration but shows differences relating to the components as well as the
port interconnections.
The reachable directly neighboring but unconfigured PROFINET devices are also displayed;
there is however no status display for these neighboring PROFINET devices.
Requirement
For error-free operation of the topology, the following conditions must be met:
● You completed the language settings.
● The topological interconnection of the ports is configured in the topology editor of STEP 7
● The project is compiled in STEP 7.
