9.1.8 Monitoring activity via Heartbeat
By means of the
function the activity of a device in the CANopen network can be monitored
by the master. The device regularly sends a Heartbeat message containing the device status.
The Heartbeat function is activated by entering a value greater than "0" into the Heartbeat interval time
object (OV index 0x1017). The value indicates the time between two Heartbeat signals in milliseconds.
The Heartbeat function is deactivated with the value "0".
9.1.9 Change objects
in the object directory are applied at once. The changes will get lost by a reset.
To prevent this the objects have to be saved in the internal permanent memory (flash). All the objects
marked in the object directory with "Save object value: yes" are permanently stored in the flash of the
device. By writing the command "Save" (65766173h) to save the objects (OV index 1010h/01h) all
current objects of the object directory are transferred to the flash memory.
The objects can be reset to factory setting by writing the signature "Load" (64616F6Ch) to the OV
index 1011h/01h. After a reset the changes are applied.
Depending on the architecture of the CANopen network the objects can also be stored centrally in a
CANopen master. In this case the objects are transferred to the device when the system is started and
the locally stored values are overwritten.
Special features of the objects
(OV index 0x20F0 and 0x20F1) and the bit rate (OV
index 0x20F2 and 0x20F3):

Changes of the objects are only applied after a reset.

The objects cannot be transferred to the flash via the OV index 1010h/01h.

The objects cannot be reset to the factory setting via the OV index 1011h/01h.
