5. Applications

5.1. Setting and reading objects

To overwrite or read an object (SDO), two telegrams are always sent.
Set object
First the Master sends the value to be set. Then the encoder sends the confirmation.
Value (ba) is sent:
COB-ID
DLC Command
600h+Node-ID
8
Confirmation:
COB-ID
DLC Command
580h+Node-ID
8
Read object
First the Master sends a request for the desired object. Then the encoder sends the requested value.
Request from Master:
COB-ID
DLC Command
600h+Node-ID
8
Response (dcba) of encoder to the request:
COB-ID
DLC Command
580h+Node-ID
8
Commissioning
When the encoder is connected to the bus, it reports with a BootUp message. Now the encoder must be
adapted to its environment and configured.
Change Node-ID and baud rate with LSS
The Node-ID and baud rate can be changed without having to address the encoder via these. With the LSS
service the sensors are addressed and configured via ProductCode, RevisionNo, VendorID and
SerialNumber.
Change Node-ID (Node No.)
The Node-ID can be changed in Object 2101h between 1 and 127. Then a save should be carried out with
Object 1010h. During the next initialization the encoder then reports with the new Node-ID.
