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

Parameterising via SDO

For parameterising via the PDO2 (FHPP−FPC, see
appendix B.2), conversion is not required.

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).
