10 Using the NodeBuilder FX/PL Example
Testing the I/O Devices on the Gizmo 4 I/O Board
You can use the I/O devices on the Gizmo 4 I/O Board to observe how network variable connections
enable devices to exchange data. You can use a switch device to control a lamp device on the Gizmo 4
I/O Board. You can then set an alarm condition, trigger the alarm and activate the piezo buzzer and an
LED on the Gizmo 4 I/O Board, and then use a switch device on the Gizmo 4 I/O Board to
acknowledge the alarm and turn off the buzzer and LED.
A connection may be between a single output network variable and a compatible (same type) input
network variable, or it may be between a single output or input network variable and multiple
compatible input or output network variables, respectively. Once you create a connection, the input
network variables will receive all updates from the output network variables in the connection.
Testing Switch and Lamp Devices
To test the network variable connection between switch and lamp devices on the Gizmo 4 I/O Board,
follow these steps:
1. In the Miscellaneous Digital Equipment box, right-click the connector shape between Button 2
and LED2, and click Monitor Output Value on the shortcut menu. Right-click the connector
shape again and click Monitor Input Value on the shortcut menu.
