Chapter 10 CANopen Function and Operation
10.4.4 Example of Sending SDO through the Ladder Diagram
The following uses DVP-ES3 as a demonstration example. For EX3/SV3/SX3, the operations are all the
same.
1. Control Requirement:
Read the value of P0-09 from the servo through SDO.
2. Hardware Connection:
3. The Corresponding Relation between Slave Parameter and Index/Subindex
The index_subindex corresponding to P0-09 in servo is 2009_0. In the CANopen Builder network
configuration software, right click the servo icon, and then click Parameter Edit. In the Parameter Edit
dialog box, you can see the index_subindex corresponding to the servo parameter.
For more details on how to operate the network configuration interface, refer to Section 11.1.1 in the
