Creating and Using a Custom Data Point Master SmartShape
You can create a custom data point master SmartShape from an existing Data Point SmartShape, and
you can include a Data Point SmartShape with other SmartShapes in a custom OpenLNS CT master
SmartShape. All the properties of the Data Point SmartShape—including the selected data point, label,
fonts, and colors—are saved in the custom master SmartShape. You can then re-use the custom data
point master SmartShape to add new Data Point SmartShapes to your OpenLNS CT drawing.
Creating a Custom Data Point Master SmartShape
To create a custom functional block master SmartShape, drag the desired Data Point SmartShape or a
set of SmartShapes that includes a Data Point SmartShape onto an OpenLNS CT stencil to which you
have write access.
If the Use Subsystem Absolute Path check box in the Data Point Shape dialog box is selected when
you create the custom data point master SmartShape, the monitored data point will be the same as the
one in the original Data Point SmartShape when you drag the master SmartShape to your drawing.
If this option is cleared, OpenLNS CT will store a relative reference in the custom data point master
SmartShape of the subsystem path from the location of the original (source) Data Point SmartShape to
that of the monitored object. OpenLNS CT will then use this information to determine the data point
to be monitored when you create a new Data Point SmartShape from the custom master SmartShape.
Using a Custom Data Point Master SmartShape
You can create a custom Data Point SmartShape by dragging a custom Data Point master SmartShape
from an OpenLNS CT stencil to your drawing. The custom Data Point SmartShape has the same
properties as the original Data Point SmartShape that you used to create the master SmartShape. To
create a new Data Point SmartShape from a master SmartShape, follow these steps:
1. Drag the custom data point master SmartShape from its stencil to your OpenLNS CT drawing.
The Data Point Shape dialog box opens with a default data point selected.
2. The default data point depends on whether the Use Subsystem Absolute Path option was selected
in the original Data Point SmartShape. If this option was selected, the default data point is the
same as the one in the original Data Point SmartShape. If this option was cleared, OpenLNS CT
will try to identify the appropriate default data point based on the subsystem in which the new
Data Point SmartShape was created and the relative path to the original Data Point SmartShape.
3. Accept the default data point or select a different data point to be monitored in the new Data Point
SmartShape.
4. Click OK. The Data Point SmartShape is added to your OpenLNS CT drawing.
If you drag a custom OpenLNS CT master SmartShape that includes a Data Point SmartShape to your
OpenLNS CT drawing, the new Data Point SmartShape will be created without the Data Point Shape
dialog opening.
Note: If the Use Subsystem Absolute Path option was cleared, and you change the name of any of
the objects (subsystem, device, functional block, or the data point object) referenced by the master
SmartShape, and you drag the master SmartShape to a different subsystem, OpenLNS CT may not be
able to determine the appropriate data point for the new Data Point SmartShape. If OpenLNS CT
cannot determine the data point, the new Data Point SmartShape will be outlined red (the default style
for Connection Unbound).
Example: A subsystem named “Subsystem 1,Building1.Floor1.Room1” contains a Data Point
SmartShape, and the Use Subsystem Absolute Path check box for the Data Point SmartShape is
cleared. The Data Point SmartShape references a data point on a functional block in the “Subsystem
1.Building1.Floor2.Room10” subsystem. The subsystem path stored in the Data Point SmartShape is
therefore “^.^.Floor2.Room10”. This indicates that when the custom Data Point master SmartShape is
added to a drawing, OpenLNS CT is to attempt to locate the monitored object by moving two
