Heartbeat message
The heartbeat mechanism for a CANopen device is established by cyclically transmitting the
heartbeat
message by the heartbeat producer. One or more CANopen devices in the network are
aware of this
heartbeat message. If the heartbeat cycle fails for the heartbeat producer the local
application on the
heartbeat consumer will be informed about that event.
If a CANopen device starts with a value for the heartbeat producer time unequal to 0 the
boot-up message is regarded as first heartbeat message.
