3.12.3 CANopen Protocol
The interface is driven via the CANopen interface as defined in CIA DS301,
V4.0 (CAN in Automation e.V., Erlangen, Germany).
The protocols integrated into the device are described briefly below.

All CANopen nodes are in one of the following operating states: initialisation,
pre-operational, operational or stopped.
After power-up, the initialisation state is executed and entries in the object
index are set to their default values.
Either all communications-specific entries, or only those included in the
object index (1000
h
-1FFF
h
), can be reset to their default values at any time
with the help of the “reset node” and “reset communication” commands.
The device then enters the pre-operational state.
The device is switched to the operational state after issuing the “start remote
node” command.
The device can be switched to the stopped state through use of the “stop
remote node” command.
Return to the pre-operational state is made possible with the “enter pre-
operational state” command.
