4.1 General Considerations
i
PROFINET is supported from SW Version 02.00
PROFINET transmits parameter data, configuration data, diagnostic data, alarm messages, and process data be-
tween the host system (IO controller) and the controllers that are part of the fieldbus (IO devices). Depending on
their time-critical behavior, data are transmitted via corresponding communication channels.
4.1.1 Communication channels
 The process data channel transmits time critical process data. Process data are transmitted cyclically be-
tween the IO controller and the IO devices.
 With the process data the controller is actuated.
 The IO controller can directly access the process data. In the PLC, for instance, the data are directly assigned
to the IO area.
 Process data are e.g. setpoints, actual values, control and status words.
i
There is one channel for incoming (RX) and one channel for outgoing (TX) information:
Incoming data (Rx data): Process data from the inverter (IO device) to the IO controller
Outgoing data (Tx data): Process data from the IO controller to the inverter (IO device)
 Parameter data are transmitted via the acyclic channel.
 Usually the transmission of parameter data is not time-critical.
 The access to the parameter data uses the PROFIdrive profile.
 Examples of parameter data are operating parameters, motor data, and diagnostic information.
 The acyclic channel provides access to all drive parameter objects.
 Parameter changes must be saved via parameter 0x2022:3 (P700:3)
