PROFINET ENCODERS FROM DATALOGIC
PROFINET encoders from Datalogic fulfill the requirements of the Application Classes 3
and 4, thus they are intended for clock-synchronous (isochronous) real-time applica -
tions with cyclic and synchronous data transmission. Anyway they can also be used in
applications without clock synchronization. For detailed information on the application
classes refer to "
Application Class definition" on page 45
.
PROFINET encoders support the telegrams 81 and 860. Further information can be
found under "
Telegrams" on page 48
.
The IO data is transferred to and from the Encoder Object (EO, see "
Encoder Object
model" on page 46
) via the Cyclic Data Exchange Service. The EO comprises the following
mandatory functionalities:
• parameters;
• measuring task (i.e. position value, velocity value, …);
• IO data (cyclical transmission of control and actual values);
• support for Alarm Mechanism.
Among the parameters available in the Profinet encoders from Datalogic: code
sequence, scaling function, preset (Class 4 functionalities), position readout, offset
value, velocity value, velocity measuring unit, acyclic Error Data communication and
diagnostic information.
