6.6 Cyclic data transmission PROFIBUS DP
Below is a description of the cyclic data transmission when using the Prosonic Flow 93 GSD file
(complete device functionality).
6.6.1 Block model
The block model illustrated shows which input and output data Prosonic Flow 93 provides for cyclic
data exchange via PROFIBUS DP.

6.6.2 Modules for cyclic data transmission
The measuring device is a so-called modular PROFIBUS slave. In contrast to a compact slave, the
structure of a modular slave is variable - it consists of several individual modules. In the GSD file,
the individual modules (input and output data) are described with their individual properties. The
modules are permanently assigned to the slots, i.e. the sequence or arrangement of the modules
must be observed when configuring the modules (see following table). Gaps between configured
modules have to be assigned the EMPTY_MODULE module.
To optimize the data throughput rate of the PROFIBUS network, it is recommended to only
configure modules that are processed in the PROFIBUS master system.
