IL•1F CANopen DS301

3.1.3Objects

All processes under CANopen are executed via objects. Objects carry out different tasks; they act as communication objects for data transport to the fieldbus, control the process of establishing a connection or mon- itor the network devices. If objects are directly linked to the device (de- vice-specific objects), the device functions can be used and changed via these objects.

Object dictionary The object dictionary of each network device allows for communication between the devices. Other devices find all objects with which they can communicate in this dictionary.

Figure 3.2 Device model with object dictionary

Objects for describing the data types and executing the communication tasks and device functions under CANopen are included in the object dictionary.

Object index Every object is addressed by means of a 16 bit index, which is repre- sented as a four-digit hexadecimal number. The objects are arranged in groups in the object dictionary.

Index (hex)	Object groups	Supported
		by the drive

0000h	Reserved	No
0001h-009Fh	Static and complex data types	No
00A0h-0FFFh	Reserved	No
1000h-1FFFh	Communication profile, standardized in DS 301	Yes
2000h-5FFFh	Manufacturer-specific device profiles	Yes
6000h-9FFFh	Standardized device profiles, e.g. in DSP 402	No
A000h-FFFFh	Reserved	No

Object group data types Data types are used so that the messages that are transmitted via the network as bit streams have the same meaning for the transmitting and
