8.9.9 Types of SDO
Service Data Objects (SDOs) allow a device‘s data to be accessed by using
explicit requests� The SDO service is available if the device is in the "Operational"
or "Pre-Operational" state�
There are two types of SDOs
– Read SDOs (Download SDOs)
– Write SDOs (Upload SDOs)
The SDO protocol is based on a Client/Server model
Download SDO The client sends a request indicating the object to be read� The server returns
the data contained within the object�
Upload SDO The client sends a request indicating the object to be written to with the required
value� After the object has been updated, the server returns a confirmation
message�
Unprocessed SDO The server returns an error code (80) in both cases if an SDO could not be
processed�
