Updating an Enumerated Data Point
To set the value of an enumerated data point, follow these steps:
1. If OpenLNS CT SmartShape menus are not enabled, click Add-ins, click OpenLNS CT, and then
select Use OpenLNS CT Shape Menus.
2. If updates are not enabled, right-click the Data Point SmartShape, select Properties on the
shortcut menu, and then select the Enable Value Updates check box in the Data Point Shape
dialog. Click OK.
3. Right-click the enumerated data point and point to Set Value on the shortcut menu. A list of all

Getting a Data Point Value
You can get the value of any data point by double-clicking the Data Point SmartShape or right-clicking
the Data Point SmartShape and clicking Get Value on the shortcut menu. The Data Point SmartShape
value is updated with the current value of the data point. OpenLNS CT must be attached to the
network to use this option.
If monitoring on the Data Point SmartShape is disabled, the value displayed in the Data Point
SmartShape will be cleared in n seconds, where n is the value set in the ‘Get Value’ Display Duration
box in the Network Properties: NV Browser/Monitoring options category. By default, the value is
15 seconds. You can disable the clearing of the Data Point SmartShape by setting this value to 0. To
set this value in the OpenLNS drawing, click Add-ins, click OpenLNS CT, click OpenLNS CT
Options, then select NV Browser/Monitoring from the Options Category list. See NV
Browser/Monitoring Options in Appendix A for more information on setting this value.
