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 an RJ45 plug.
Autocrossing is always active on X2. This means the RJ45 socket is allocated either as data
terminal equipment (MDI) or a switch (MDI‑X).
Unplugging the PROFINET‑plug
You need a screwdriver (max. blade width 2.5 mm) to remove the PROFINET plug.
Removing the display
You can find a description of how to remove and replace the display in the S7‑1500,
ET 200MP (http://support.automation.siemens.com/WW/view/en/59191792) system manual.
Reference
You can find additional information on the topics of "Connecting the CPU" and
"Accessories/spare parts" in the S7-1500, ET 200MP

Assignment of the MAC addresses
CPU 1515‑2 PN has two PROFINET interfaces, with the first interface having two ports. The
PROFINET interfaces each have a MAC address, and each of the PROFINET ports has its own
MAC address. The CPU 1515‑2 PN therefore has five MAC addresses in total.
The MAC addresses of the PROFINET ports are needed for the LLDP protocol, for example for
the neighborhood discovery function.
