Subject:
How is it possible to record a complete Wireshark capturing of the entire bus telegram
data exchange on the Profinet IO?
Description:
Profinet IO networks are set up with switches. A switch port cannot be used for monitoring
useful analyser records since a switch port only passes on the message belonging to the
IP address assigned.
There are two options to carry out Wireshark monitoring of the Profinet IO:
1.
A Profinet switch is used which is equipped with the Mirroring Enable function. Such a
function is available from e.g. Siemens SCALANCE switch series X204 and higher and
can be activated via the web browser.

An Ethernet hub also provides the function to monitore a complete Profinet IO network
since ALL messages are passed on at every hub port and not just only those telegrams of
the IP addresses assigned. It is also possible to use the Lenze Ethernet Powerlink hub
(type E94AZCEH) for this purpose. The hub is to be located directly after the Profinet IO
Master as shown in the picture below. As a result, the complete Profinet IO network can
be captured.
