3.6 Device profiles for fieldbuses
3.6.1 Device profile: Festo handling and positioning profile (FHPP)
Independent of the fieldbus used, a uniform control concept can be implemented through the device
profile “FHPP”. The user does not have to know the specific functions of the respective fieldbuses or
controllers, but can commission and control the drive in t he shortest possible t ime through a uniform
profile.
F HPP distinguishes between the triggering methods “record selection” and “direct operation”.
With record selection, the positioning records parametrised in the motor controller are used.
In the direc t mode, the following operating modes c an be used:
– Positioning mode (position control)
– Speed mode (speed adjustment)
– Force/torque mode ( current control)
The o perating modes can be switc hed over in direct operation as needed.

3.6.2 Device profile: CANopen, CiA 402 (for electric drives )
Through the device profile “CiA 402”, the following operating modes can be used:
– Positio ning mode (CiA 402: Profile position mode)
– Homing mode (CiA 402: Homing mode)
– I nte r polating position mode (CiA 402: Interpolated position mode)
– Speed mode (CiA 402: Profile velocity mode)
– Force/torque mode (CiA 402: Profile torque mode)
Communication can take place either over SDOs (ser vice data objec ts) and/or PDOs (process data
objects). Up to 2 PDOs are available for each sending direction (transmit/receive).
