IObjectDictionary.RaiseReadObject (METH) ¶ METHOD RaiseReadObject : ABORT_CODE Used to raise a read object event. All IODCallback instances (also associated CANopen stack) will be informed. Returns ABORT_CODE.SUCCESSFUL if reading is permitted else error reason.

Needed for IODCallback handlers to do range checks. udiSize UDINT Size of Bytes to be written

IObjectDictionary.ReadObject (METH) ¶ METHOD ReadObject : ABORT_CODE Used to read an object of the local object dictionary. If ABORT_CODE.SUCCESSFUL is returned pbyData contains the read data. If error occured the corresponding abort code is returned. Difference to IObjectDictionary.ReadObjectByAddress : Better performance because itfObject is an input variable => no internal binary search necessary.

Reading a writeonly object will fail. FALSE : Ignore access rights and force reading. xDataInBusOrder BOOL Specifies in which Byte Order data should be read; TRUE : Data should be read in CANopen Byteorder (Little Endian), FALSE : Data should be read in Host Byte Order pbyData POINTER TO BYTE Pointer to data where the object value should be copied to. Inout udiSize UDINT VAR IN: Size of memory pbyData points to; VAR OUT: Size of object

IObjectDictionary.ReadObjectByAddress (METH) ¶ METHOD ReadObjectByAddress : ABORT_CODE Used to read an object of the local object dictionary. If ABORT_CODE.SUCCESSFUL is returned pbyData contains the read data. If error occured the corresponding abort code is returned. InOut: Scope Name Type Initial Comment Return ReadObjectByAddress ABORT_CODE ABORT_CODE.SUCCESSFUL : Reading successful, pbyData contains data; ELSE: Reading not permitted Input wIndex WORD Index of object which should be read bySubIndex BYTE Subindex of object xCheckAccess BOOL TRUE TRUE : Access rights should be checked. Reading a writeonly object will fail.

Inout udiSize UDINT VAR IN: Size of memory pbyData points to; VAR OUT: Size of Object

IObjectDictionary.GetObject (METH) ¶ METHOD GetObject : IODObject Used to get an object with a specific index. InOut: Scope Name Type Comment Return GetObject IODObject Object with given Index or 0 if no such object Input wIndex WORD Index of object

IObjectDictionary.GetObjectToWrite (METH) ¶ METHOD GetObjectToWrite : ABORT_CODE Used to search for an object and checking general write permission (access rights and data size). Returns ABORT_CODE.SUCCESSFUL if writing is allowed. Only needed if writing permission should be checked without writing immediately to the object. InOut: Scope Name Type Initial Comment Return GetObjectToWrite ABORT_CODE ABORT_CODE.SUCCESSFUL : Object writing permitted; ELSE: Writing not permitted Input wIndex WORD Index of object which should be written bySubIndex BYTE Subindex of object xCheckAccess BOOL TRUE TRUE : Check access rights, FALSE : do not check access rights udiSize UDINT size of data to be written Output itfObject IODObject requested object itfSubObject IODSubObject requested subobject

IObjectDictionary.WriteObject (METH) ¶ METHOD WriteObject : ABORT_CODE Used to write an object in the local object dictionary. If ABORT_CODE.SUCCESSFUL is returned data in pbyData was copied to the object. If error occured the corresponding abort code is returned. Difference to IObjectDictionary.WriteObjectByAddress : Better performance because itfObject is an input variable => no internal binary search necessary. InOut: Scope Name Type Initial Comment Return WriteObject ABORT_CODE ABORT_CODE.SUCCESSFUL : Writing successful, object value was changed according to pbyData; ELSE: Writing not permitted Input itfObject IODObject Object which should be written. bySubIndex BYTE Subindex of object xCheckAccess BOOL TRUE TRUE : Access rights should be checked. Write on readonly object will fail. FALSE : Ignore access rights and force writing. xDataInBusOrder BOOL Specifies Byte Order of data pbyData points to; TRUE : Data in CANopen Byteorder (Little Endian), FALSE : Data in Host Byte Order pbyData POINTER TO BYTE Pointer to data which should be written to the object Inout udiSize UDINT VAR IN: Size of memory pbyData points to; VAR OUT: Size of Object

IObjectDictionary.WriteObjectByAddress (METH) ¶ METHOD WriteObjectByAddress : ABORT_CODE Used to write an object in the local object dictionary. If ABORT_CODE.SUCCESSFUL is returned data in pbyData was copied to the object. If error occured the corresponding abort code is returned. InOut: Scope Name Type Initial Comment Return WriteObjectByAddress ABORT_CODE ABORT_CODE.SUCCESSFUL : Writing successful, object value was changed according to pbyData; ELSE: Writing not permitted. Input wIndex WORD Index of object which should be written bySubIndex BYTE Subindex of object xCheckAccess BOOL TRUE TRUE: Access rights should be checked. Write on readonly object will fail. FALSE: Ignore access rights and force writing. xDataInBusOrder BOOL Specifies Byte Order of data pbyData points to; TRUE: Data in CANopen Byteorder (Little Endian), FALSE: Data in Host Byte Order pbyData POINTER TO BYTE Pointer to data which should be written to the object Inout udiSize UDINT VAR IN: Size of memory pbyData points to; VAR OUT: Size of Object

ObjectIterator.MoveNext (METH) ¶ METHOD MoveNext : BOOL Sets the iterator to the next object. This object can be retrieved afterwards by property |ObjectIterator.Current|. Method returns ``TRUE` if iterator was successfully moved. Method returns FALSE e.g. if end of list. InOut: Scope Name Type Comment Return MoveNext BOOL TRUE : Current points to the next object, FALSE : MoveNext failed, e.g. if end of list.

ObjectIterator.ObjectDictionary (PROP) ¶ PROPERTY ObjectDictionary : IObjectDictionary IObjectDictionary where the iterator is connected to. Iterator will be automatically resetted if ObjectDictionary will be set.
