Topology rules
Topology rules for RT
● A topology can be, but need not be configured for RT. If a topology has been configured,
the devices must be wired in accordance with the topology.
● Otherwise, the wiring between devices is entirely optional.
Topology rules for IRT
● Mixed operation is not supported by STEP 7 V5.4 SP4, i.e. IRT "high performance" cannot
be combined with IRT "high flexibility" in the same synchronization domain.
● A synchronization domain with IRT "high performance" can contain a maximum of one IRT
"high performance" island. "Island" means that the devices must be interconnected to match
the configured topology. A synchronization master must be positioned in the relevant island.
● IRT "high flexibility" is subject to the same topology rules as for IRT "high performance",
the only exception being that a topology does not need to be configured. However, if a
topology has been configured, the devices must be wired to match the topology.
Device selection in HW Config
Hardware catalog:
The drive unit from the appropriate device family entry in the hardware catalog must be
configured. For the real-time class IRT, these are all entries as of firmware version V2.5.
GSDML:
GSDML files for devices which contain IRT as of firmware version V2.5.
A.1.3.3 PROFINET GSDML
SINAMICS supports the GSDML version: "PROFINET GSDML" to embed the converter in a
PROFINET network.
PROFINET GSDML allows standard telegrams to be combined with a PROFIsafe telegram –
and if required, a telegram extension. Each of the modules has four subslots: The Module
Access Point (MAP), the PROFIsafe telegram, a PZD telegram to transfer process data and
where necessary, a telegram for PZD extensions. Example:
GSDML-V2.31-Siemens-Sinamics_S_CU3x0_20160101.xml
You can download GSDML files from the following Siemens Internet address:
PROFINET GSDML (

The GSDML files on the memory card are saved in the following location: ..\SIEMENS
