5.6.3 Properties of PROFINET
Properties
The onboard PROFINET IO interface supports the parallel operation of:
● IRT - isochronous real-time Ethernet
– Operation of IRT I/O (e.g. ET 200S)
– Operation of a SINAMICS S120 as IRT device
● RT - real-time Ethernet
– Operation of RT I/O (e.g. ET 200S, ET 200pro, etc.)
– Operation of a SINAMICS S120 as an RT device
● TCP/IP, UDP, HTTP, … standard Ethernet services
Note
For mixed operation of IRT and RT, make sure that the IRT-compatible devices form what is
referred to as an IRT domain; i.e. there must not be any non-IRT devices on the data
transmission link between the IRT devices.

5.6.4 Configuration tasks
Configuration of PROFINET involves the following steps:
1. Insert the SIMOTION D4x5-2.
2. Configure the onboard PROFINET IO interface in HW Config.
3. Create a topology: Here, you specify how the individual ports of the PROFINET IO
devices are interconnected.
4. Configure the sync domain: Here, you specify which PROFINET nodes are sync masters
(clock generators) and sync slaves.
5. Specify the send clock: Describes the time during which a PROFINET IO device
exchanges user data with the PROFINET IO controller.
6. Configure the direct data exchange: The direct data exchange specifies which address
areas are to be used for sending and receiving respectively.

PROFINET IO with SIMOTION" of the
SIMOTION Communication
System Manual.
