Defining the user data length
The user data length is defined during the initialisation phase (configuration). Up to 12
process data words can be configured (depending on the basic device used).
Optionally you can activate the parameter data channel. If the parameter data channel is
active, it additionally occupies 4 words of the process data inputs and outputs.
ƒ PIW: Process data input word (process data from the controller to the master)
ƒ POW: Process data output word (process data from the master to the controller)
The user data lengths for process input data and process output data are identical. The
selection takes place via identification bytes in the configuration software for the
PROFIBUS system.
