Siemens SIMATIC S7-1500R/H

PROFINETinterface X1 with 2-port switch (X1P1R and X1 P2R)
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).

PROFINET interface X2 with 1 port (X2P1)
The assignment corresponds to the Ethernet standard for a RJ45 connector.
Autocrossing is always active on X2. This means the RJ45 socket is allocated either as data
terminal equipment (MDI) or a switch (MDI-X).
H-Sync X3 interface with 1port (X3P1) and X4 with 1port (X4P1)
Make the redundancy connections between the two CPUs via the synchronization modules at
the X3P1 and X4P1 interfaces (LC sockets). You interconnect the CPUs in pairs via the fiber-
optic cables.
