Additional information
You can find additional information on the topic of "Connecting the CPU" and on the topic
"Accessories/spare parts" in the system manual for Redundant System S7‑1500R/H

Assignment of the MAC addresses
For each CPU, CPU 1517H‑3 PN has:
• One PROFINET interface with two ports
• One PROFINET interface with one port
• Two H‑Sync interfaces with one port each
Each of the interfaces has a MAC address. Each port also has a separate MAC address. There
are a total of eighteen MAC addresses for the two CPUs of the CPU 1517H‑3 PN.
The MAC addresses of the ports are needed for the LLDP protocol, for example for the
neighborhood discovery function.
The number range of the MAC addresses is sequential. The first and last MAC addresses are
printed on the rating plate on the right side of each CPU 1517H‑3 PN.
The table below shows how the MAC addresses are assigned.

(visible in STEP 7 when devices are accessible)
MAC address 2 Port X1 P1R (required for LLDP, for example)
MAC address 3 Port X1 P2R (required for LLDP, for example)
MAC address 4 PROFINET interface X2
(visible in STEP 7 when devices are accessible)
MAC address 5 Port X2 P1 (required for LLDP, for example)
MAC address 6 H-Sync interface X3
MAC address 7 Port X3 P1
MAC address 8 H-Sync interface X4
MAC address 9 Port X4 P1
