Chapter 13. Node DS301 Command
Reference
This chapter describes the Maestro object Node DS301, its functionality and the
available CANopen objects.
Node DS301 – The CANopen device supports the CiA CAN DS301 protocol. The
Maestro device provides the ability to work with the Elmo Motion Axis, DS402 Motion
Axis, DS401 CAN I/O and simultaneously treat them as DS301 Node objects. To
access the Elmo Axis (or the DS402 Axis or the DS 401I/O) object via the CAN DS301
protocol, you must create a DS301 Node object for the same CAN ID.
The Maestro object supports the following CANopen services for Node DS301:
NMT Service
Sync and timestamp
Emergency handling
Send PDO (process data object)
Receive PDO (carried out by Callback Functions).
Download SDO (service data object)
Upload SDO
