5.2.3 Normal operation (DDLM_Data_Exchange mode)
In the normal mode (DDLM_Data_Exchange mode), data are
exchanged between master and slaves. The preset function can
be carried out only in this operating mode. The data exchange is
described in chapter 5.5.
5.3 Configuration, DPV0
The configuration of a DPV0 device is conducted by choosing
encoder class, i.e. setting the input/output data structure. The
configuration options are 16-bit, 32-bit or 32-bit + 16-bit
velocity input data, for explanation view chapter 4.1.
5.4 Parameterization, DPV0
The PROFIBUS-DPV0 device is parameterized by means of
the operating parameters. The values selected in the
configuration tool are saved in the DP master and are
transferred to the PROFIBUS-DP slave each time the network
is started. The following table lists all available parameters:
Parameters Data type Parameter
