Table 15:
Structure of consumer heartbeat time entry (Unsigned16)
6.4.4 Object 1017
hex
Producer Heartbeat Time
A CANopen node uses heartbeat signals to tell all the other nodes on the
CANopen network that it is ready for operation, even if there have not been
any data transfers for an extended period of time.
Object 1017
hex
defines the interval (cycle time) for this heartbeat.
All nodes can register when a CANopen node drops out!
If the interval = 0, a heartbeat will not be used. The object's content is inter-
preted as a multiple of 1 ms.
A node cannot use the heartbeat function in combination with node guarding.
If the two monitoring mechanisms are enabled simultaneously, the node will
use the heartbeat protocol only.
