6.2.1 Overview of the encoder profiles

6.3 Application Class definition

The encoder profile defines two application classes: Class 3 and
Class 4. A number of mandatory functions are specified for each
application class, in addition all optional functions must be
recognized by the encoder and handled so that the controller is able
to determine whether an optional function is supported.
NOTE
There is no relation between the Encoder application classes and the
application classes defined in the PROFIdrive profile.

6.3.1 Application Class 3

Encoder with base mode parameter access and limited
parametrization of the encoder functionality. Isochronous mode is not
supported.

6.3.2 Application Class 4

Encoder with scaling, preset, isochronous mode and base mode
parameter access. A Class 4 configured encoder fully supports all
functionalities according to the encoder profile V4.1.
Datalogic Automation encoders fulfill the requirements of CLASS 4

6.4 Encoder Object model

The Figure shows the general Encoder Object (EO) architecture.
Central element of the EO is the Measuring Task where the
measurements are made and the results are calculated. The
properties of the EO is represented and controlled by parameters.
