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.
