112 Designing Networks
4. Right-click the subsystem and click Expand from the network navigator. All devices, functional
blocks, and available network variables in the network hierarchy will be displayed. Select one or
more network variables to be supernodes. To select all the available network variables, click
Select All from the network navigator.
5. Click OK. Shapes for the selected network variables appear on the subsystem shape.
Tips: You can connect supernodes just as you would use network variables on a functional block. See
Creating Connections in this chapter for more information on connecting network variables.
You should limit the number of network variables on a single supernode to 30. Having more than 30
network variables will degrade your network’s performance.
Re-Naming and Deleting a Supernode Network Variable
You can change the name or delete an unconnected supernode network variable shape. Changing the
name of or deleting a supernode network variable shape will not affect the naming or presence of the
source network variable.
To change the name of a supernode network variable, click the subsystem shape and click the network
variable shape you want to rename. Right-click the selected network variable shape, select Properties
from the shortcut menu, and enter a new name in Exported Name box in the Network Variables
Properties dialog box.
To delete a network variable from a supernode, click the subsystem shape and click the network
variable shape you want to delete. Right-click the selected network variable shape and select Delete
from the shortcut menu.
Copying a Subsystem or Supernode
You can copy a subsystem or supernode to create a new subsystem or supernode with the same
devices, functional blocks, connections, and configuration as the original, including any nested
subsystems and supernodes.
To copy a subsystem or supernode, follow these steps:
1. Right-click the subsystem or supernode shape to be copied and click Copy on the shortcut menu.
2. Right-click anywhere in the LonMaker drawing, in the same or in a different subsystem, and click
Paste on the shortcut menu. The New Subsystem Wizard appears.
