PROFIBUS DP interface
You can connect the distributed I/O to the PROFIBUS DP interface.
PROFINET IO interface
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 find further information on PROFINET IO in sections PROFINET IO systems (Page 52).
The meaning of the interface labels is as follows:
When media redundancy is activated, the corresponding port is configured as a ring port.
NOTICE
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.
