8. Change network variable and configuration property values and confirm that the device hardware

works as designed. For example, toggle a hardware input and observe the value of the
corresponding output network variable change. You can then change the value of an input
network variable and observe the hardware output change based on the value you entered.

For more information on using the LonMaker Browser, see Chapter 6 of the LonMaker User’s Guide.

Note: If these steps do not generate the expected result, open the NodeBuilder tool and check your
code. You can also use the NodeBuilder Debugger to help troubleshoot problems (for more
information, see Chapter 10, Debugging a Neuron C Application).

Connecting NodeBuilder Devices

Once you determine that your device is functioning as desired, you can test it as part of a network.
You can use the LonMaker tool to connect your development devices to other devices and verify their
operation within a network. This entails creating functional blocks, connecting the network variables
within the functional blocks, and verifying that the network variable values are updated appropriately
when you use the I/O devices on your device hardware.

Note: You can connect an output network variable of a device to one or more compatible input
network variables on the same device. These connections are referred to as turnaround connections.

To connect your NodeBuilder device, follow these steps:

1. Open the LonMaker drawing that contains the NodeBuilder device. The device must be built and

it must be associated with the appropriate LNS device template.

2. Drag a Functional Block shape from the NodeBuilder Basic Shapes 4.00 stencil or the

LonMaker Basic Shapes stencil on the left of the LonMaker window to the drawing.

3. The Functional Block wizard opens. You will use this wizard to associate the new functional

block shape with your NodeBuilder device and the desired functional block.

4. In the Functional Block wizard, do the following:

a. In the Name property under Device, select your NodeBuilder device.

b. In the Name property under Functional Block, select a functional block from those defined

in the device interface.
