Using A Second Profinet Interface - Siemens SIMOTION D4 5-2 Series Commissioning And Hardware Installation Manual

5.6.2.4

Using a second PROFINET interface

With the SIMOTION D4x5-2 DP/PN control units, optionally a second PROFINET interface is
available as of V4.3 in addition to the onboard PROFINET interface (X150) with the Ethernet
communication board (CBE30-2, X1400).
The CBE30-2 can only be operated in the D4x5-2 DP/PN control units, use in the D4x5-2 DP
control units is not possible.
Applications
A CBE30-2 can be used, for example, for the following applications:
● The second PROFINET interface is used
● Devices are to be operated with different send cycle clocks and assigned different
● Devices are to receive an independent IP address area or NameOfStation (e.g. higher-
● I device and controller are to be operated isochronously at the same time.
Rules for two PROFINET interfaces
The following rules must be taken into account when using two PROFINET interfaces, if both
interfaces are to be operated isochronously (an isochronous device or an isochronous I
device or data exchange broadcast is configured at the interface):
● Both interfaces can be configured as a PROFINET IO I device and/or as a controller.
● A higher-level controller must always be connected isochronously via the CBE30-2.
● The onboard PROFINET interface must be configured as sync master.
● The CBE30-2 can be configured as sync master or sync slave.

level network as plant network; local network for machine module; nodes in the "local
network" can be addressed separately from the nodes in the "plant network").
If one PROFINET interface is operated simultaneously as I device and controller, either
only the I device or only the controller can be operated isochronously (i.e. with IRT). With
two PROFINET interfaces, it is possible to operate a PROFINET IO controller and an I
device isochronously on a D4x5-2 DP/PN at the same time.
This applies both for the controller-controller communication and also for the I device
communication to a higher-level controller. Lower-level isochronous drives/I/Os should be
connected via the onboard PROFINET interface.
