The PROFINET IO interfaces establish the connection to Industrial Ethernet. The
PROFINET IO interfaces also serve as the access point for the engineering system. The
PROFINET IO interfaces feature two switched ports with external connectors (RJ 45). You
can connect IO devices to the first PROFINET IO interface X5. The interface X8 is designed
as service interface and cannot be used as PROFINET IO interface. You will find additional
information about PROFINET IO in the sections PROFINET IO systems (Page 89).
Connecting only to Ethernet LAN
These interfaces only allow connection to an Ethernet LAN. You cannot connect them to
the public telecommunication network, for example.
You may only connect PROFINET IO-compliant network components to this interface.
