Representation of parameter data
The 24 bytes of parameter data for the XNE-1SWIRE module are represented by the
manufacturer specific objects of the CANopen gateway.
The following manufacturer specific objects for representing the parameter data are
used:
•
3060
hex
, “XBI Param Byte”, ARRAY, Unsigned8
•
3062
hex
, “XBI Param Word”, ARRAY, Unsigned16
•
3064
hex
, “XBI Param Dword”, ARRAY, Unsigned32
•
3065
hex
, “XBI Param Dword2”, ARRAY, Unsigned32
•
3066
hex
, “XBI Param Dword3”, ARRAY, Unsigned32
•
3067
hex
, “XBI Param Dword4”, ARRAY, Unsigned32
•
3068
hex
, “XBI Param Dword5”, ARRAY, Unsigned32
•
3069
hex
, “XBI Param Dword6”, ARRAY, Unsigned32
•
306A
hex
, “XBI Param Dword7”, ARRAY, Unsigned32
•
306B
hex
, “XBI Param Dword8”, ARRAY, Unsigned32
The objects have the following structure:
•
The objects have a maximum of 74 sub-indexes. This number corresponds to
the number of modules that are present on a XI/ON station. The sub-index corre-
sponds to the module number of the XI/ON module.
•
A sub-index can represent a maximum of 4 bytes. Larger parameter data
volumes are distributed on the following objects. The sub-index also belongs to
the module number.
The following table shows the assignment of the parameter data bytes of the XNE-
1SWIRE module to the manufacturer specific objects:
Tab. 22 Representation of the parameter bytes of the XNE-1SWIRE module
Use the objects 3064
hex
to 3069
hex
to access all the parameter data! The
parameter bytes of the XNE-1SWIRE module are represented complete-
ly with the objects 3064
hex
and 3069
hex
. The sub-index of the objects
must correspond to the slot of the module in the XI/ON station.
The structure of the parameter data of the XNE-1SWIRE module is de-
scribed in Chapter 3.1.4 Parameter, Page 33. This description is followed
by a table with explanations on the meaning of the individual bits.
