Description
The Entry ID 49311792 gives you an overview of the PROFINET IO controllers and IO devices of SIMOTION and SINAMICS that support the PROFINET functions above.
Isochronous real-time communication (IRT)
Synchronized transmission procedure for cyclic exchange of IRT data between PROFINET devices. There is a bandwidth reserved for the IRT data in the transmitter clock. The reserved bandwidth guarantees that the IRT data can be transmitted at reserved, clock-synchronized intervals even when the network is otherwise heavily loaded (with TCP/IP communication or additional real-time communication, for example).
Prioritized startup
Prioritized startup is the PROFINET functionality for accelerating the startup of an IO device in a PROFINET IO system with RT and IRT communication.
The function cuts the time needed by the appropriately configured IO devices to get back into the cyclic user data communication in the cases below:
- After return of power supply
- After station return
- After IO device enabling
Medium redundancy protocol (MRP)
Medium redundancy is a function for ensuring that availability of networks and plants. Redundant transmission paths (ring topology) ensure that when one transmission path fails an alternative path is made available.
PROFIenergy
Function for saving power in the process, during idle times, for example, through temporary switch-off of the encoder and load supply in the potential group via standard PROFIenergy commands.
More information about PROFIenergy is available in the manuals ready for downloading in the Entry IDs below.

Send and receive (PROFIenergy) data records
- With SFB73 "RCVREC" you receive the (PROFIenergy) data records in the I device of the higher-level IO controller.
- With SFB74 "PRVREC" you make the (PROFIenergy) data records in the I device available to the higher-level IO controller.

Shared device
IO device that makes its data available to multiple IO controllers.
I device
Using the I device function you can use an IO controller also as IO device and thus establish a separate lower-level PROFINET IO subnetwork.
An I device can also be used as a shared device.
Clock-synchronized mode for process data
Process data, transmission cycle via PROFINET IO and user program are synchronized with each other to achieve the highest deterministics. The input and output data of distributed IOs in the plant is captured and output simultaneously. The equidistant PROFINET IO cycle is the clock for this.
