31 position set records can be saved in the MTR-DCI. A record
contains all the parameters which are specified for a posi-
tioning task. The record number is transferred to the cyclical
I/O data (FHPP standard) as a nominal or actual value.
FHPP-FPC Optionally, an additional 8 bytes of I/O data can be used as a
parameterisation access via FPC (Festo Parameter Channel ).
The additional bytes can be configured via the I/O data
length (HMI, FCT software).

Tab. 1/5: Data profile
If the FPC is not required in normal operation, the data length
can be reduced to 8 bytes to optimise the PLC access for
cyclic data transfer. Parameter changes can still be done
using “Explicit messaging”.
Detailed information on FHPP can be found in chapter 5.5
onwards.
