Property Description
represents the time of day the configuration of the Data Point
was last updated, in UTC (Coordinated Universal Time).
UTC is the current term for what was commonly referred to as
Greenwich Meridian Time (GMT). Zero (0) hours UTC is
midnight in Greenwich England, which lies on the zero
longitudinal meridian. Universal time is based on a 24 hour
clock; therefore, an afternoon hour such as 4 pm UTC would be
expressed as 16:00 UTC. The Z appended to the timestamp
indicates that it is in UTC. It can be left out.
For example, 2002-08-15T10:13:13Z indicates a UTC time of
10:13:13 AM on August 15, 2002.
If it is not UTC, time shift has to be defined:
2008-02-28T09:59:53.660+01:00
A user-defined description of the device. This can be a
maximum of 201 characters long.

device. This property is
always LON_Device_Cfg.htm.
The handle of the device assigned by the LNS server. When
you use the Set function to modify the configuration of an
existing device, you must specify the device’s handle. If you do
not specify the handle, a new device is created. You cannot use
the Set function to modify the handle assigned to the device.
The current Neuron ID of the device. The Neuron ID is a
unique 48-bit number that is burnt into the Neuron chip of an
external device or assigned to one of the SmartServer's 16
internal devices.
The program ID of the device as a set of hex digits. The
program ID uniquely defines the static portion of the device
interface. It is hard coded into an external device (in the
EEPROM of the device’s Neuron Chip), and it is assigned the
16 internal devices on the SmartServer. You should not change
this property for external or internal devices.
The waypoint of the device. A waypoint is a set of coordinates
(latitude and longitude) that identifies the device’s location in
physical space. Typically, waypoints are acquired with a GPS
and then uploaded to the SmartServer using SOAP/HTTP
messages over the console port.
The 6-byte hexadecimal location string that documents the
device’s location within the network.
The maximum number of dynamic functional blocks that you
can add to the device.
A dynamic functional block is a functional block that is not
