3.1 Terminal assignment

PROFINET interface X1 with 2-port switch (X1 P1 R and X1 P2 R)

The assignment corresponds to the Ethernet standard for an RJ45 plug.

• When autonegotiation is deactivated, the RJ45 socket is allocated as a switch (MDI-X).

• When autonegotiation is activated, autocrossing is in effect and the RJ45 socket is

allocated either as data terminal equipment (MDI) or a switch (MDI-X).

Figure 3-1

PROFINET interface X2 with 1 port (X2 P1) and X3 with port (X3 P1)

The assignment corresponds to the Ethernet standard for a RJ45 connector.

Autocrossing is always active on X2 and X3. This means the RJ45 sockets are allocated either

as data terminal equipment (MDI) or a switch (MDI-X).
