2. Following steps 3–6 in Creating Dynamic Network Variables Using Network Variable
SmartShapes, change the default name, if desired, enter the number of new dynamic network
variable(s) you are creating, and set the poll attributes and the message service type and options.
3. Click OK to add the dynamic network variable to the functional block.
Changing a Network Variable Name
You can change the network variable name on a functional block. OpenLNS CT will record the
change in the OpenLNS CT drawing and in the OpenLNS network database. To change the name of a
network variable, click its functional block and then click the network variable SmartShape.
Right-click the network variable SmartShape, click Properties on the shortcut menu, and then enter
the new name in the Name box. OpenLNS CT only requires that network variable names be unique
within a functional block; therefore, if you list all the network variables in a device, some may have
duplicate names.
Changing Network Variable Position
Once a functional block has a network variable SmartShape placed on it, the network variable
SmartShape becomes part of the functional block SmartShape. If you move the functional block
within the drawing or from one subsystem to another, the network variable will remain in the same
position on the functional block.
You can change where a network variable SmartShape is positioned on a functional block. To change
the location of a network variable SmartShape, click its functional block, click the network variable
SmartShape, right-click the network variable SmartShape, and then clear Automatic Positioning if it
is currently selected. You can then move the selected network variable SmartShape up or down on the
functional block.
Deleting a Network Variable SmartShape
You can remove unconnected network variable SmartShapes from one or more functional blocks.
To delete a network variable SmartShape from a single functional block, follow these steps:
1. Click the functional block with the network variable you want to remove.
2. Click the network variable SmartShape.
3. Right-click the network variable SmartShape.
4. Click Delete on the shortcut menu.
To delete a network variable SmartShape from multiple functional blocks, follow these steps:
1. Delete any connections to the network variable on all the functional blocks. You cannot remove a
connected network variable from a functional block.
2. Right-click the functional block.
3. Click Delete NVs and MTs on the shortcut menu. The Delete Network Variable/Message Tag
dialog box opens.
