Property Description
<UCPTvalueDef>
The value definition being used by the data point. If the data point is not using a
value definition, or if you defined the <UCPTfieldName> property in the input you
supplied to the function, this field will appear blank.
Value definitions are user-defined strings that represent preset values the data
point can be updated to. For example, the value assigned to a value definition
called ON for a SNVT_switch data point might be “100.0 1.” You can create value
definitions for a data point with the DataServerSet function, or with the
i.
LON 100
Configuration Software.
<UCPTunit>
Unit type of the data point. This property is configured based on the network
variable type of the data point.
<UCPTpointStatus>
The current status of the data point. This property is updated in real time by the
Data Server, and can be used when setting up Alarm Generators and Alarm
Notifiers with the
i.
LON 100. You can create Alarm Generators and Alarm
Notifiers with the
i.
LON 100 Configuration Software, or with the SOAP interface.
For information on using the SOAP interface to create Alarm Generators and
Alarm Notifiers, see Chapters 7 and 8 of this document.
<UCPTpriority>
The priority level currently assigned to the data point. You can set the priority
level of a data point with the DataPointWrite or DataPointResetPriority functions.
For more information on priority levels, see Data Point Values and Priority Levels
on page 3-5.
<UCPTformatDescription>
The format description of the data point. This determines many factors about the
data point, including the type of values it takes, and its base type. This could be
any standard (SNVT) format type included in the
i.
LON 100 resource files, or any
user-defined (UNVT) format type included in resource files uploaded to the
i.
LON
100. For more information on the
i.
Files on page 4-8.
The SNVT format types included in the
i.
LON 100 resource files are also listed and
described in the SNVT Master List, which can be downloaded as a PDF by
selecting the Documentation link on Echelon’s Support Web site:
<UCPTbaseType>
This read-only property is assigned to the data point automatically based on the
data point’s <UCPTformatDescription>. It defines the base type of the data point,
as defined in the base_type_t enumeration in the BAS_Controller resource files for
the
i.
LON 100.
