<strong>CANopen</strong>-<strong>Slave</strong><br />
Dictionary entries of the data type OBJ_ARRAY and OBJ_RECORD store the<br />
number of sub-entries in the format UNSIGNED8 as an RO entry at subindex 0.<br />
For arrays this entry is created automatically. For records this isn’t the case for<br />
historical reasons, which means the application has to define the entry at subindex<br />
0 as TYP_UINT8 in the descriptor string to be compatible with the current<br />
revision of the specification /1/.<br />
Example for a single value or array descriptor of data type INTEGER32:<br />
const char *DescrSimple[] = {TYP_INT32, 0};<br />
Example for a record descriptor of a INTEGER32 at sub-index 1 and an<br />
INTEGER16 at sub-index 2. The UNSIGNED8 entry at sub-index 0 is also<br />
defined:<br />
const char *DescrComplex[] = {TYP_UINT8, TYP_INT32, TYP_INT16, 0}<br />
Return: 0 or an error code described in the appendix.<br />
