5.4.4 Parameterising via SDOs
DS402 With data profile DS402, parameterising takes place via SDOs
with the aid of the object numbers as per appendix C.2.
FHPP With data profile FHPP, conversion is required for paramet−
erising via SDOs: 2000h + PNU in hexadecimal representaĆ
tion.
Example of access to the object Cycle number:"
DS402:
2FFFh
Cycle
number
2FFFh
FHPP:
PNU 305d => 131h
2000h + 131h =
2131h
Fig. 5/1: Parameterising via SDO
For parameterising via the PDO2 (FHPP−FPC, see
appendix B.2), conversion is not required.
5.4.5 PDO mapping
The mapping is pre−set and cannot be altered by the user
(static mapping").
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 transĆ
mitted via CAN (lower−value byte first).
