PROFINET interface X1 with 2-port switch (X1 P1 R and X1 P2 R)
The pin assignment of the ports depends on the setting of the port option "Activate
autonegotiation".
● Port P1 X1 R: When autonegotiation is deactivated, the RJ45 socket is allocated as data
terminal equipment MDI (normal pin assignment).
● Port P2 X1 R: When autonegotiation is deactivated, the RJ45 socket is allocated as a
switch MDI-X (crossed pin assignment).
● The following applies to both ports: 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.
The figure below shows the location of the PROFINET interface X1 and the connection
socket for the 24 V DC supply voltage.
