3.4.3. Service data communication 

The service data objects comply with the CiA standards.  An object can be accessed via an index and 
subindex.  The data can be requested or, if necessary, written to the object.

Data 0  Data 1  Data 2  Data 3 

 
An SDO 

COB-ID

 consists of the following: 

Master -> Encoder 

: 600h + Node-ID 

Encoder -> Master 

: 580h + Node-ID 

 

DLC

 (data length code) designates the length of the telegram.  This consists of the following: 

1 byte c 2 bytes 1 byte su number of data bytes (0 - 4). 
 
The 

command byte

 specifies whether data are read or set and how many data bytes are concerned:

Abort Message 

- 

Encoder signals error code to Master 

 
An 

abort message

 indicates an error in the CAN communication.  The SDO command byte is 80h.  The 

object and the subindex are those of the desired object.  The error code is present in byte 5 - 8.
