Addressing
In the delivery condition, the onboard PROFINET IO interface does not have an IP address or
a subnet mask.
Note
The IP addresses 192.168.215.240 to 192.168.215.255 are reserved for internal
communication in the SIMOTION D4x5‑2 (subnet mask 255.255.255.240). When configuring
the PROFINET interface (X150), make sure that the internal addresses are not located within
the network of this interface. In IP, the network is defined as an AND link of IP address and
subnet mask.
Media redundancy (MRP), as of V4.3
It is possible to establish redundant networks via the Media Redundancy Protocol (MRP).
Redundant transmission links (ring topology) ensure that an alternative communication path
is made available when a transmission link fails. The PROFINET devices that are part of this
redundant network form an MRP domain.
MRP guarantees media redundancy in the event of a problem in the ring. The switchover of
the ring is performed by the Redundancy Manager.
The switchover times depend on:
● The actual topology
● The devices used and
● The network load in the relevant network
The typical reconfiguration time of the communication paths for TCP/IP and RT frames in the
event of a fault is < 200 ms.
In most systems, the switchover time of MRP is far above the PROFINET update time for cyclic
data, so that a failure for cyclic data is detected. The PROFINET connection therefore fails
and is reestablished after the switchover by the Redundancy Manager. In this way, an error
can be corrected in the network, while the system continues to run with bumps.
Note
During the interruption of the ring, as well as when correcting the interruption (e.g. repair of
the defective cable), there is a brief failure of the communication.
Ring ports
A SIMOTION/SINAMICS device may only be inserted in an MRP ring as a node with MRP-
capable ports. For SIMOTION D, the first two ports of the PROFINET IO interfaces are
designed as ring ports.
