4.3 Device profile: Encoder Profile V4.1
Application Class 4
The PROFIBUS and PROFINET profile for encoders is a
further development of the PROFIBUS profile for DPV2
encoders. The profile is an extension of the PROFIdrive
profile. The profile defines two application classes (class 3
and class 4).
The BTL supports application class 4 for encoders with
scaling function, preset, isochrone mode, and parameter
access.

4.3.2 Standard signals
The position interface defined in the profile is a
standardized connection between the sensor and the
controller. Some defined standard signals serve for I/O
data configuration. The signal numbers correspond to
those of the PROFIdrive profile.
