1.15 What does network management (NMT service) mean?
Note
In the "Pre-operational" status, only SDO communication is possible; PDO communication is
inhibited.
In the "Operational" status, PDO communication also takes place.
The diagnostics LED -> green (CANopen RUN LED) indicates the status.

Services
After power-on, the Control Unit automatically switches to "Initialization".
After initialization, it switches to "Pre-Operational".
Start_Remote_Node command (CS = 128)
Enter_Pre-Operational_State command (CS = 128)
Stop_Remote_Node command (CS = 2)
Reset_Node command (CS = 129)
Reset_Communication command (CS = 130)
command for switching from the "Pre-Operational" communication status to
"Operational". The drive can only transmit and receive process data in the "Operational"
status.
command for switching from "Pre-Operational" to "Stopped" or from "Operational" to
"Stopped". The node can only process NMT commands in the "Stopped" status.
command for switching from "Operational" or "Stopped" to "Pre-Operational". In the "Pre-
Operational" status, the node cannot process any PDOs. It can, however, be
parameterized or operated via SDOs, which means that setpoints can also be specified.
command for switching from "Operational", "Pre-Operational", or "Stopped" to
"Initialization". When the Reset Node command is issued, all the objects (1000 hex -
9FFF hex) are reset to the status that was present after "Power On".
command for switching from "Operational", "Pre-Operational", or "Stopped" to
"Initialization". When the Reset Communication command is issued, all the
communication objects (1000 hex - 1FFF hex) are reset to their original status.
