3.1.3. DP process data
Process data are data memories where several individual parameters
are combined to form a new parameter, the process data. These
process data are exchanged as fast as possible and cyclically between
the controller and the master.
Process data can be divided into process output data (PO data) and
process input data (PI data), viewed from the master, that means PO
data are input data for the controller. The controller receives control
information from the master and supplies feedback information to the
master. Process data have a fixed length of 4 byte. A summary of
parameters is described in the chapter "process data configuration"
(page 67).

Important note
•
If a parameter is set to the process output data, such as for example
DRIVECOM control word in the above table, the parameter (e.g. index
6040
hex
) may not be written directly.
