the device has not yet been commissioned.

11 Program ID mismatch. The ID of the program in the device does not

match the program ID in the network image.

12 Unable to verify domain/subnet/node configuration. Succeeded in

communicating with the device using Neuron ID addressing, but
could not communicate with the device using subnet/node
addressing. Because the device has authentication enabled, no
attempt is made to verify that the device has been configured with
the proper domain/subnet/node address because reading the
address would result in transmitting the key over the network.

13 Authentication configuration mismatch. Authentication is enabled in

the device, but disabled in the network image.

14 Authentication configuration mismatch. Authentication is disabled in

the device, but enabled in the network image.

15 Authentication key mismatch. The authentication key in the device

and the system’s authentication key do not match.


Note:
This test is only reliable if the device's network image is up to date.
For example, if you made changes to a device while Offnet and tested it
before going Onnet, the test may fail.

return only the first 95 characters of the description.

ASCII string. The string may not be meaningful in ASCII format, and if a
byte holds a zero value, the string will end there even if bytes that follow
have a non-zero value.

The value of the device’ s or router’s six byte location string as a hex string
of twelve characters.

The frequency with which a device is tested (pinged) by the LNS Server to
determine if it is still attached to the network. The values returned by this

2

Temporary device – 2 minute ping.

3

Stationary device – 15 minute ping.

4

Permanent device – no ping.

ServicePin.Count

R/W

Number of service pin messages received from the device.

Attachment.Found

R/W

Number of attachment events where the device was responding. Tallies
the number of times contact was restored with the device after previously
failing to respond to pings from the LNS Server. The Attachment.Found
value will be less than or equal to the Attachment.Lost value unless the
properties are written by the client application.

Attachment events are only generated for devices which are pinged by the
LNS Server.

Attachment.Lost

R/W

Number of attachment events where this device failed to respond. Tallies
the number of times contact was lost with the device after previously
succeeding.

Attachment events are only generated for devices which are pinged by the
LNS Server.

Attachment.IsAttached

True if the last attachment event for this device indicated the device was
responding, False if it did not respond.
