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 H80
represents all nodes. Only the NMT Master is allowed to send NMT node control messages.
The NMT state is shown in BFM #601 to #727.
At the NMT Master, an NMT message can be requested can be via an SDO write access. Consider using this
carefully because the NMT Startup Master will not set the Target Node automatically back to Operational
until the next reset if the request is a Stop or Pre-Operational request!
→
For the BFM assignment corresponding to the NMT state of each node, refer to Section 6.22
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.
