Assignment of the MAC addresses
CPU 1518-4 PN/DP ODK has three PROFINET interfaces. The first interface is an interface
with 2-port switch. The PROFINET interfaces each have a MAC address, and each of the
PROFINET ports has its own MAC address. The CPU 1518-4 PN/DP ODK therefore has
seven MAC addresses in total.
The MAC addresses of the PROFINET 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 address are
lasered on the rating plate on the right side of each CPU 1518-4 PN/DP ODK.
The table below shows how the MAC addresses are assigned.
