Device Profile - Profile for Encoder V1.1
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:
•
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.
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:
7
configurations
are
available
for
the
regular
operation
of
the
encoder:
