5.4.4 Parametrizing via SDOs
DS402 With data profile DS402 parametrizing is made via SDOs with
the aid of the object numbers as per appendix C.1.
FHPP With data profile FHPP conversion is required for parametriz
ing via SDOs: 2000h + PNU in hexadecimal representation.
Example of access to the object Cycle number":
DS402:
2FFFh
Cycle
number
2FFFh
FHPP:
PNU 305d => 131h
2000h + 131h =
2131h
Fig.5/1: Parametrizing via SDO
For parametrizing via the PDO2 (FHPP−FPC, see appendix B.1)
conversion is not required.
5.4.5 PDO mapping
The mapping is pre−set (static mapping") and cannot be
altered by the user.
Note
If the data on the master side are not in the same form, but
saved, i.e. as byte array:
·
note that the representation of words and double words
appears in the little endian" representation when trans
mitted via CAN (lower−value byte first).
