4.8.8 Request

NMT

This object indicates at the NMT Master the current NMT state of a unique CANopen

device in the

network. The sub-index corresponds to the node-ID of the CANopen

devices in the network. The

sub-index 80

represents all nodes. Only the NMT Master is allowed to send NMT node control mes-

sages.

A NMT message can be requested by using the SDO write access in the NMT master. Please consider
to use this carefully, because if the request is a

Stop

Pre-Operational

request, the NMT start-up mas-

ter will not set the target node back to

Operational

automatically until the next restart.

Object 1F82

to 80

: Request NMT

NOTE

If a node for heartbeat consuming is activated and a boot-up message is received from this node,
the NMT state

Pre-operational

will be displayed for this node until the next heartbeat is received

for this node.
A read access is possible by using the buffer memory (refer to section 3.5.16).
