44 Application Note ET9300
Member Data type Description
Write Pointer to Write Function. The prototype is
listed below. This function will be called
when an SDO download is received. If this
pointer is NULL the standard SDO
download function is executed.
Prototype:
UINT8 WriteFunction(
UINT16 index,
UINT8 subindex,
UINT32 dataSize,
UINT16 MBXMEM * pData,
UINT8 bCompleteAccess )
NonVolatileOffset unsigned 16 bit determine offset within nonvolatile memory.
This value is evaluated if the object should
be stored(load) as backup parameter.
Example: Object dictionary entry description (Object Code VARIABLE)
TOBJECT VarObj_ODEntryDesc = {0x6000, {DEFTYPE_UNSIGNED32, 0 | (OBJCODE_VAR
<< 8)}, &VarObjectEntryDesc, VarObjName, &u32VarObject, NULL, NULL, 0x0000
};
Example: Object dictionary entry description (Object Code ARRAY)
TOBJECT ArrObj_ODEntryDesc = {0x9000, {DEFTYPE_UNSIGNED32, 5 | (OBJCODE_ARR
<< 8)}, ArrObjEntryDesc, ArrObjName, &ArrObj, NULL, NULL, 0x0000 };
Example: Object dictionary entry description (Object Code RECORD)
TOBJECT RecObj_ODEntryDesc = {0x7000, {DEFTYPE_RECORD, 4 | (OBJCODE_REC <<
8)}, RecObjEntryDesc, RecObjName, &RecObj, NULL, NULL, 0x0000 };
7.6 Index Ranges
The index ranges depends on the used EtherCAT profile. See Ref.[5] for further information.
The Basic index ranges used in the SSC are listed in Table 6: Basic object index ranges.
