Profibus encoder profile V1.1
The PROFIBUS DP device profile describes the functionality of the communication
and the manufacturer-specific component within the PROFIBUS fieldbus system.
The encoder profile applies to encoders and defines the individual objects
independently of the manufacturer. In addition, the profile makes provision for
additional extended functions specific to the manufacturer. The use of PROFIBUS
compatible devices ensures that the systems of today are ready to meet the
demands of the future.
The following parameters can be programmed
• Direction of rotation.
• Scaling – number of steps per revolution.
• Preset value.
• Diagnostics mode.
The following functionality is integrated
• Galvanic isolation of the bus stage with DC/DC converter.
• Line driver acc. to RS485 max. 12 MB.
• Full class 1 and class 2 functionality.
• Speed value.
