information’s
PROFIBUS is a continuous, open, digital communication system with a broad range of
applications, particularly in manufacturing and process automation. PROFIBUS is
suitable for fast, time-sensitive and complex communication tasks.
PROFIBUS communication
is based on the international standards IEC 61158 and
IEC 61784. The application and engineering aspects are defined in the PROFIBUS
User Organization guidelines. These serve to fulfil the user requirements for a
manufacturer independent and open system where the communication between
devices from different manufacturers is guaranteed without modification of the devices.
The PROFIBUS User Organization has implemented a special profile for encoders.
The profile describes the connection of rotary, angular and linear encoders with single
turn or multi turn resolution to the DP. Two device classes define the basic and
additional functions, e.g. scaling, alarm management and diagnosis.
The measuring systems support Device Classes 1 and 2 as defined in the profile, as
well as additional TR-specific functions.
A description of the encoder profile (order no.: 3.062) and further information on
PROFIBUS is available from the PROFIBUS User Organization:

4.1 DP Communication protocol
The measuring systems support the
DP
communication protocol, which is designed for
fast data exchange on the field level. The basic functionality is defined by the
performance level
V0
. This includes cyclic data exchange, as well as the station,
module and channel-specific diagnosis.
