Echelon LNS DDE Server - Manual (Page 107)

Point.InError R Number of points that cannot be read in the network.
Point.WriteCount R Number of write requests issued for this point.
The number of writes issued may not exactly match the aggregate count of updates issued
by all clients for a point. The server will fold together all currently queued write requests for
a single point. This also means that if two separate fields in a point are updated at nearly
the same time, there is a good chance that the server will only need to issue one write
request to update both fields.
Point.WriteErrors R Number of times a write operation has failed.
This count only applies to errors that occur after the server has accepted and queued an
update request. An update with a value that the server immediately recognizes as invalid, is
not counted.
Point.UpdateErrors R Number of times the LNS Server has reported an error when attempting to poll a network
variable, or when some other problem occurred when trying to start polling a network
variable or reading a configuration property.
CP.RefreshRate R/W This is the update interval for configuration properties as well as some system, device, and
point properties.
Changing this value will only affect points that are accessed after the change, not points that
are currently being accessed.
ServicePin.Count R/W Number of service pin messages received.
ServicePin.Handle R/W Handle for the device that last issued a service pin message.
ServicePin.NeuronId R/W Neuron ID for the device that last issued a service pin message. A string of twelve
characters with the hexadecimal value of the Neuron ID of the device that issued the service
pin message.
ServicePin.ProgramId R/W Program ID for the device that last issued a service pin message, represented as a
hexadecimal string.
ServicePin.Location R/W Location string for the device that last issued a service pin message, represented as a
hexadecimal string.
Attachment.Found R/W Number of attachment events for found devices. Tallies the number of devices that were
found on the network after failing previously when pinged by 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 for lost devices. Tallies the number of devices that fail to
respond to ping messages from the LNS Server.
Attachment events are only generated for devices which are pinged by the LNS Server.
Device and Router Properties
Application device and router properties provide access to values and functions for
individual devices on a network. Although the properties available for these two
types of devices overlap to some extent, there are differences.
The list of supported properties below has been partitioned into three parts; common
properties, application device only properties, and router only properties.
Some properties are stored in the LNS database, while others require the
information to be fetched from the device. In case the server can’t read a specific
property from the device, the property is set to zero.
Note: It is possible to have application devices and routers with the same name, in the
same subsystem. When attempting to read a router property, and an application
