2.5 Communication services and used port numbers
SINAMICS converters support the communication protocols listed in the following table. The
address parameters, the relevant communication layer, as well as the communication role
and the communication direction are decisive for each protocol. You require this information
to match the security measures for the protection of the automation system to the used
protocols (e.g. firewall). The security measures are restricted to Ethernet and PROFINET
networks.
The following table shows the various layers and protocols that are used.

covery and config-
uration
DCP is used by PROFINET to
determine PROFINET devices
and to make basic settings.
DCP uses the special mul-
ticast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organizationally
Unique Identifier
LLDP

PROFINET Link
Layer Discovery
protocol
LLDP is used by PROFINET
to determine and manage
neighborhood relationships
between PROFINET devices.
LLDP uses the special mul-
ticast MAC address:
01-80-C2-00-00-0E
MRP
Media Redundancy

PROFINET medi-
um redundancy
MRP enables the control of
redundant routes through a
ring topology.
MRP uses the special mul-
ticast MAC address:
xx-xx-xx-01-15-4E,
xx-xx-xx = Organizationally
