6.3 PNO Encoder Profile
With this configuration the measuring system supports the PNO Encoder Profile (Profile-ID
0x3D00) defined by the PROFIBUS User Organization according to Version 4.2. The measuring
system only supports Application Classes 3 and 4 defined there:
● Application Class 3:
Measuring systems with access to basic parameters and limited parameterization of the
measuring system functionality. Isochronous mode is not supported.
Area of application: Normal automation systems
● Application Class 4:
Measuring systems with access to basic parameters and additional scaling and preset function.
Isochronous mode is supported.
Area of application: Motion control applications
The Encoder Profile is normally based on the
PROFIdrive Profile
specified for drives. Many
concepts and functionalities have therefore also been transferred to the Encoder Profile.
Only the mandatory PROFIdrive-related parameters (9xx / 600xx) are supported by the measuring
system.
6.3.1 Structure of the cyclic process data
A series of standard signals are available for the configuration of the cyclic data exchange, according
to the PROFIdrive drive profile:
