182 Monitoring and Controlling Networks
Using Data Point SmartShapes
You can use a Data Point SmartShape in an OpenLNS CT drawing to monitor the value of any
network variable configuration property, or functional block state (enabled or in override). You can
also use a Data Point SmartShape to update the value of an input network variable or configuration
property. You can use Data Point SmartShapes to create simple human-machine interface (HMI)
applications within your OpenLNS CT drawing.
Adding and Monitoring a Data Point SmartShape
You can add a Data Point SmartShape to your OpenLNS CT drawing, and use it to monitor a network
variable configuration property, or functional block state. To add a Data Point SmartShape to your
OpenLNS CT drawing, follow these steps:
1. Drag a Data Point SmartShape ( ) from the OpenLNS CT Basic Shapes stencil to your
OpenLNS CT drawing. The Data Point Shape dialog box opens.
This dialog provides a hierarchal view of your OpenLNS CT network, listing the objects in your
network in the order of subsystems, devices, functional blocks, functional block states, network
variables, and then configuration properties.
2. Select the network variable, configuration property, or functional block state to monitor by
browsing through the network hierarchy. You can also right-click a subsystem and click Expand
from the network navigator to display all the objects in that subsystem, including any nested
subsystems and their objects.
3. Optionally, you can select the following basic attributes for the selected data point.
Enable Monitoring Enables monitoring for the selected data point. Creates a monitor
set and monitor point for a network variable data point if one is
selected. All network variable Data Point SmartShapes and
monitored network variable connections in the same subsystem are
placed in one OpenLNS monitor set.

Subsystem Path Controls how OpenLNS CT interprets a new Data Point
SmartShape created from a copy (an existing Data Point
SmartShape or a master SmartShape). This check box is cleared by
