3.1 Terminal assignment
Assignment of the MAC addresses
For each CPU, CPU 1515R-2 PN has:
● One PROFINET interface with two ports
● One PROFINET interface with one port
Each of the PROFINET interfaces has a MAC address and each of the PROFINET ports has
its own MAC address. There are a total of ten MAC addresses for the two CPUs of the
CPU 1515R-2 PN.
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 addresses
are printed on the rating plate on the right side of each CPU 1515R-2 PN.
The table below shows how the MAC addresses are assigned.
