[BFM #601 to #727] NMT State

This BFM displays the NMT status of the CANopen
®
CANopen Object Dictionary). Use the SDO Command in the CIF to set the NMT state of the whole network
or of one specific node. For NMT Slaves, the NMT Status is only displayed for Nodes for which Heartbeat
Consuming is configured.
If the NMT Master is using Heartbeat Consuming or Node Guarding, the current NMT State of an NMT Slave
will display its actual NMT State as long as error control messages are received. For Nodes for which no error
control service is configured, the NMT Master will display the NMT state from the last request.
Note
• If a NMT state request is made to all nodes, all BFM displays will change.
To activate the display of a missing mandatory device, configure the Boot time out (refer to Object
Dictionary Index H1F89) and set this Node-Id as a mandatory CANopen
Index H1F81).
• If no error control service is configured or if error control messages are missing, it is possible that an NMT
state other than the actual remote NMT state will displayed. Use these BFMs and BFM #900 to #963 NMT
Error Control Status and BFM #29 to detect error control service failures.
