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.

DCP is used by
PROFINET to determine
PROFINET devices and
to make basic settings.
DCP uses the special
multicast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organization-

LLDP is used by
PROFINET to determine
and manage neighbor-
hood relationships be-
tween PROFINET

MRP enables the control
of redundant routes
through a ring topology.
MRP uses the special
