Assignment of the MAC addresses
The CPU 1512C-1 PN has a PROFINET interface with two ports. The PROFINET interface
itself has a MAC address, and each of the two PROFINET ports has its own MAC address.
The CPU 1512C-1 PN therefore has three 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 continuous. The first and last MAC address are
lasered on the rating plate on the right side of each CPU 1512C-1 PN.
The table below shows how the MAC addresses are assigned.
