Overview of Profinet IO
To connect to the Profinet IO, the Profinet IO module must be integrated in the Oil-
Guard 2 W.
The module has an internal switch and provides two Ethernet ports.
The cable is connected directly to the RJ45 plug of the Profinet IO module inside the in-
strument or via external M12 connectors.
When connecting directly to the RJ45 plug, please note that only plugs with a short
and flat design can be used.
In the
Digi.interf.\General
menu, the
Modul type
must be set to
Profinet IO
.
In the
Digi.interf.\Profinet
menu, the station name, MAC address and connection sta-
tus are shown. Moreover, it can be defined here whether the data should only be read
or be read and written.
