2. Festo Handling and Positioning Profile (FHPP)
Festo has developed an optimised data profile, the „Festo Handling and Positioning Profile
(FHPP)“, tailored to the target applications for handling and positioning tasks.
The FHPP enables uniform control and programming for the various field bus systems and
controllers from Festo.
In addition it defines the following for the user
• operating modes,
• I/O data structure,
• parameter objects,
• sequence control.

2.1 Data exchange in the DeviceNet
DeviceNet was developed by Rockwell Automation and the ODVA (Open DeviceNet Vendor
Association) as an open fieldbus standard based on the CAN protocol. DeviceNet belongs
to the CIP−based networks. CIP (Common Industrial Protocol) forms the user interface of
DeviceNet and defines the exchange of:
• explicit messages with low priority, e.g. for configuration or diagnosis
• I/O messages, e.g. time-critical processing data
