To optimize the data throughput rate of the PROFIBUS network, it is advisable to only
configure modules that are processed in the PROFIBUS master system. Any resulting gaps
between the configured modules must be assigned to the EMPTY_MODULE.
Description of the modules
The data structure is described from the perspective of the PROFIBUS master:
• Input data: Are sent from the measuring device to the PROFIBUS master.
• Output data: Are sent from the PROFIBUS master to the measuring device.
AI module (Analog Input)
Transmit an input variable from the measuring device to the PROFIBUS master (Class 1).
Selection: input variable
The input variable can be specified using the CHANNEL parameter.

TOTAL module
Transmit a totalizer value from the measuring device to the PROFIBUS master (Class 1).
Selection: totalizer value
The totalizer value can be specified using the CHANNEL parameter.
