Property Description
<UCPTpointName>
Enter the <UCPTpointName> of the data point to be written to.
The name must begin with the following prefixes:
• NVL_ for an NVL data point
• NVC_ for an NVC data point
Note: The names assigned to NVL data points follow the
naming convention NVL_[NAME], where [NAME] represents
that progammatic name assigned to the NV when it was
created with L
ON
M
AKER
.
For example, if the progammatic name of the NV in L
ON
M
AKER
is nvo01Switch_001, the <UCPTpointName> would be
NVL_nvo01Switch. You can determine the progammatic name
of an NV in L
ON
M
AKER
by right-clicking it and selecting
Properties.
<UCPTfieldName>
Field name. This can be left empty if the data point is not a
structure, or if an entire structure is to be written to.
NOTE: If this property is defined, the <UCPTvalueDef>
property can only contain the actual value to be assigned to the
data point, and not a pre-defined value definition.
<UCPTvalueDef>
Enter either the value definition (if the <UCPTfieldName>
property is not filled in) or the actual value to be assigned to the
data point. The format of the value entered must match the
format type that the data point to be written to requires.
The value definition is a string representing a preset value.
This value must match the format type the data point requires.
You can create value definitions for a data point using the
i.
LON 100 Configuration Software
,
or the DataServerSet SOAP
function.
<UCPTpriority>
Enter the priority level to be assigned to the data point. The
priority level must be specified as an integer between 0 (highest
priority) and 255 (lowest priority). In order for your application
to update the value of a data point successfully, the priority
selected must be of equal or higher priority than that used by
the last application to write to the data point. If no priority level
is defined, the default value of 255 will be used.
For a more detailed description of priority levels, see the next
Data Point Values and Priority Levels on page 3-5.
