This profile describes a manufacturer‐independent and mandatory determination of the interface for encoders. It
is defined in the protocol, which Profibus functions are used as well as how they are to be used. This standard
permits an open manufacturer‐independent bus system.
The device profile is divided into two object classes:
Configuration
The configuration programme normally provides an input mask (screen) for parameterisation purposes, i.e. for
entering the data for resolution, count direction etc. The individual modules are listed below:
Configurations available for the regular operation of the encoder:
-
32 Bit Input/Output, consistent
-
32 Bit Input, consistent
-
16 Bit Input/Output, consistent
-
16 Bit Input, consistent
-
MUR=13 Bit and TMR=25 Bit (32 Bit Input/Output, consistent)
‐ all can combined with Speed (RPM) 16 Bit consistent or Speed (Units/s) 32 Bit consistent

• Class C1 describes all the basic functions, which the
encoder should contain.
• Class C2 contains a number of extended functions,
which must either be supported by encoders of this
class (Mandatory) or which are optional. Class C2
devices thus contain all the C1 and C2 mandatory
functions, as well as additional manufacturer‐
dependent optional functions. An address area is also
defined in the profile, which can be reserved for a
manufacturer's own proprietary special functions.
