Stage 1 provides quick and easy access to
the PROFIBUS-DP communication system.
This stage already includes sufficient data to
fulfill most requirements. Communication in
stage 1 is always carried out with a class
1 master.

The 3-stage communication concept not only enables quick and easy access, but also ensures that the system can be adapted for more
complex demands. Stage 1 is standard; stages 2 and 3 optional.
The 3-Stage Communication Concept
This concept provides quick and easy access to the PROFIBUS-DP communication system with WL circuit breakers.
Stage 2 Stage 3
The cyclic data contains certain predefined
content. It can be changed in the three basic
types and, therefore, easily adapted to
prevailing requirements (e.g. replacing
phase-to-phase voltage with the number of
operating hours). This is an additional option
to stage 1.

In stage 3, acyclic data records can, if
required, be read or written by a class 1 or
class 2 master. This is useful for requesting
a large volume of data so that it does not
have to be read cyclically (e.g. waveform
buffer data).
