FMS 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).

DRIVECOM control word in the above table, the parameter (e.g. index
6040

hex

) may not be written directly.

Access to process data

You can reach the process data via the PROFIBUS services "Read" or
"Write" with the following index:

Index = 6010

hex

Process input data

Index = 6011

hex

Process output data

Further information can be obtained from the chapter "process
data" (page 70).
