Communication services and used port numbers

SINAMICS S120 supports the protocols listed in the following table. The address
parameters, the relevant communication layer as well as the communication role and the
communication direction are specified for each protocol.
This information allows you to match the security measures for the protection of the
automation system to the used protocols (e.g. firewall). As the security measures are limited
to Ethernet and PROFINET networks, no PROFIBUS protocols are listed in the table.
The following table shows the various layers and protocols that are used.

Function Description
Accessible DCP is used by
nodes, PROFINET to determine
PROFINET devices and
PROFINET
to make basic settings.
Discovery and
configuration DCP uses the special
multicast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx =
Organizationally Unique
Identifier
PROFINET LLDP is used by
Link Layer PROFINET to determine
Discovery and manage
protocol neighborhood
relationships between
PROFINET devices.
LLDP uses the special
multicast MAC address:
01-80-C2-00-00-0E
PROFINET MRP enables the control
medium of redundant routes
redundancy through a ring topology.
MRP uses the special
multicast MAC address:
xx-xx-xx-01-15-4E,
xx-xx-xx =
Organizationally Unique
Identifier
