6.1 Read/Write Service Data Object 

 

The transfer of the Service Data Object (SDO) is done by the CMS Multiplexed 
Domain protocol (CIA DS202/2). 
 
 
 

6.1.1 Read SDO: 

 
(Initiate Domain Upload) 
 
 

Request Protocol format: 
 
 

COB-Identifier = 600h + Node-ID

n = number of data bytes ( bytes 4-7) that does not contain data. 

 
 

If only 1 data byte (Data 0) contains data the value of byte 0 is "4FH". 

 
 

If byte 0 = 80h the transfer has been aborted.
