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.

Function Description
Accessible nodes, DCP is used by PROFINET to
determine PROFINET devices
PROFINET Dis-
and to make basic settings.
covery and config-
uration DCP uses the special mul-
ticast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organizationally
Unique Identifier
PROFINET Link LLDP is used by PROFINET
Layer Discovery to determine and manage
protocol neighborhood relationships
between PROFINET devices.
LLDP uses the special mul-
ticast MAC address:
01-80-C2-00-00-0E
PROFINET medi- MRP enables the control of
