FHPP standard
FHPP standard is used for time−critical sequence control.
Here there are two FHPP operation modes:
ć Record selection:
The higher−level control (PLC) selects positioning records
(positioning tasks) stored in the SFC−LACI.
ć Direct mode:
Positioning tasks are formulated directly into the
master’s cyclical output data. Possible are positioning
mode, continuous setpoint specification and gasoline
operation.
Detailed information on the FHPP standard can be found
starting at section 5.6.
FHPP−FPC (Festo Parameter Channel)
Optionally, an additional 8 I/O bytes can be used for paraĆ
meterisation via FPC. The additional bytes are defined via the
configuration program with the GSD file, see section 5.5.
If the FPC is not needed in normal operation, the data length
can be reduced to 8 bytes (= FHPP standard) in order to
optimise the PLC access in cyclic data transfers. Parameter
changes can continue to be performed with DPV1.
Detailed information on the FHPP−FPC can be found starting
in the section B.2.
