⑤ PROFINET devices of another PROFINET IO system
• In the set topology:
A PROFINET device of another PROFINET IO system is displayed with a green connection
(or red connected if the ports have been interchanged), when it is directly adjoining a
configured and accessible PROFINET device ① and it is also accessible. When the
PROFINET device of another PROFINET IO system is not accessible, a yellow connection
line is displayed.
The connection between two PROFINET devices that both belong to a different
PROFINET IO system, cannot be determined and is always displayed in yellow.
• In the actual topology:
A PROFINET device of another PROFINET IO system is only displayed if the PROFINET
device is in direct proximity to a configured PROFINET device. The PROFINET device is
displayed light-gray and with dashed line.
For PROFINET devices of a different PROFINET IO system, no status display is shown on the
device head.
⑥ Representation of faulty neighbor relations
The devices whose neighbor relations cannot be read out completely or correctly are
displayed light-gray with red border.
Additional information
The tabular view of the actual topology and the status overview of the PROFINET devices in
the project are possible.
You can find these views, additional topology examples, and detailed information on the
operation and the functions of the Web server in the Web server
