b. Under the Device box, select OpenLNS Network Interface from the Name list.
c. Under the Functional Block box, select Virtual Functional Block from the Name list.
d. Enter the name of the Virtual Functional Block in the New FB Name box.
2. Drag an Input Network Variable SmartShape from the IzoT Commissioning Tool Basic Stencil to
the virtual functional block. The Choose a Network Variable dialog opens.
3. Click Create NV. Create a dynamic network variable, as described in Adding Network Variables
to a Functional Block in Chapter 4, Designing Networks. Select a network variable type that is
compatible with the network variable you are binding to your compute.
4. Connect the input dynamic network variable you added to the virtual functional block to the
output network variable that you want your computer to monitor.
Updating Network Variable and Configuration Property Values
You can control the values of input network variables and writeable configuration properties for the
devices in your network. You cannot change output network variable values and read-only
configuration properties.
Setting Values
To set the value of an input network variable or writeable configuration property, follow these steps:
1. Click anywhere in the row containing the input network variable (colored blue) or writeable
configuration property (green).
2. Enter a valid value in the Value box on the Browser toolbar, or choose a value from the
drop-down list if you are changing an enumerated value.
3. Click the Set Value button ( ) on the Browser toolbar, or right-click the object you are changing
and then click Set Value on the shortcut menu. The value is updated in the Value column. If you
have entered an invalid value, an error message is displayed in a Display Message dialog.
Setting Values for Structured Objects
You can use the Set Network Variable/Set Configuration Property dialog to set the value of one or
more of the fields of a structured input network variable or writeable configuration property (structured
means that the object has multiple fields).
To open the Set Network Variable/Set Configuration Property dialog, right-click the object and
click Details on the shortcut menu.
This dialog displays the name, units, and maximum and minimum values for each of the fields. For
example, a network variable with a SNVT_switch data type opens in the Value field in the Browser
with a value of 100.0 1. If you are not familiar with this network variable and try to set it in the Value
box, you may enter an invalid value or enter a value that causes a device to behave in an undesired
manner. If you open the Set Network Variable Property dialog box, you can see that this network
variable has value and state fields and view the minimum and maximum values for each of these
fields.
