Communication Services And Used Port Numbers - Siemens SINAMICS Configuration Manual

Risk of death due to software manipulation when using exchangeable storage media
Storing the parameterization (incl. Safety Integrated parameterization) on exchangeable
storage media carries the risk that the original parameterization (with Safety Integrated) will
be overwritten, for example, by the memory card of another drive without Safety Integrated.
Incorrect parameter assignment can cause machines to malfunction, which can lead to
injuries or death.
● Ensure that only the memory card that belongs to the respective inverter is used.
● Ensure that only trained or authorized personnel have access to the enclosures, cabinets

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.

Description
DCP is used by PROFI‐
NET to determine PRO‐
FINET devices and to
make basic settings.
DCP uses the special
multicast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organization‐
ally Unique Identifier
LLDP is used by PROFI‐
NET to determine and
manage neighborhood
relationships between
PROFINET devices.
LLDP uses the special
multicast MAC address:
01-80-C2-00-00-0E
