configured via the I/O data length (HMI, FCT software).

Tab. 1/4:
Data length
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. Instead of
3Ătelegrams, only one more telegram is then transmitted.
Parameter modifications can still be carried out with Explicit
Messaging".
Detailed information on the FHPP−FPC can be found starting
in the section B.2.
