1.2.3 Festo handling and positioning profile (FHPP)
Festo has developed an optimised data profile, the
Festo Handling and Positioning Profile (FHPP)", tailored
to handling and positioning tasks.
FHPP enables uniform sequence control and programming for
the various fieldbus systems and controllers from Festo.
Communication over the fieldbus can occur cyclically (PDO)
or acyclically (SDO). Mixed operation is typical:
ć Commissioning and application parameters are transĆ
mitted via SDOs.
ć Time−critical process control occurs via FHPP standard
(PDO1, 8 bytes I/O).
ć Parametrising during operation occurs via FHPP−FPC
(PDO2, additional 8 bytes I/O) or via SDO (conversion is
required
