General The inverter must be given a specific PROFINET configuration by the IO controller to
define type and number of input and output data words used for the transmission. You
have the opportunity to control the drives via process data and to read and write all pa-
rameters of the fieldbus interface in an acyclic way.
The following figure describes the data exchange between the programmable controller
(IO controller), the fieldbus interface (IO device) and an inverter with process data chan-
nel.
Configuring the
process data The PROFINET interface allows for different configurations for the data exchange be-
tween IO controller and IO device. The configurations are determined by the default pro-
cess data width for SEW inverters of three process data words. The fieldbus interface
then distributes these process data words to the individual devices. The PROFINET in-
terface accepts 1×3 to 8×3 process data words.
