Cyclical data of MICROMASTER 4 via PROFIBUS-DP

MICROMASTER 4 is controlled via the cyclical PROFIBUS-DP channel. This
channel can be used to exchange parameters.
The structure of useful data for the cyclical channel is defined in the PROFIDrive
Profile, version 2.0, and referred to as the Parameter Process data Object (PPO).
PROFIDrive Profile defines for the drives the useful data structure with which a
master can access the drive slaves using the cyclical data communication method.

Useful data structure as defined in PROFIDrive Profile 2.0 and 3.0

Useful data structure according to PPOs
The useful data structure for cyclical data traffic is divided into two areas, which
can be transmitted in each telegram as follows:
Ø
Ø
With which PPO type (see next page) the inverter is addressed by the PROFIBUS-
DP master can be defined in the configuration data for the master when the bus
system is started up. Which type of PPO is selected depends on the function of the
PROFIBUS Communication Module
