Equipment Manual, 05/2021, A5E49868646-AA
25
H-Sync X4 interface with 1 port (X4 P1) and X5 with 1 port (X5 P1)
Make the redundancy connections between the two CPUs via the synchronization modules at
the X4 P1 and X5 P1 interfaces (LC sockets). You interconnect the CPUs in pairs via the fiber-
optic cables.
①
Without module
②
With synchronization module and removed dummy plugs

Assignment of the MAC addresses
CPU 1518HF-4 PN has for each CPU:
•
One PROFINET interface with two ports
•
Two PROFINET interfaces with one port each
•
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 22 MAC addresses for the two CPUs of the CPU 1518HF-4 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 1518HF-4 PN.
