The sequence File Page Setup Options directs you to pull down the File menu, select the Page Setup item, and select Options from the last dialog icon denotes a tip, which alerts you to advisory icon denotes a note, which alerts you to important text denotes items that you must select or click in the software, such as menu items and dialog box options. Bold text also denotes parameter names, controls and indicators on the front panel, dialog boxes, sections of dialog boxes, menu names, and palette text denotes variables, emphasis, a cross-reference, or an introduction to a key concept.

4 Italic text also denotes text that is a placeholder for a word or value that you must text denotes text or characters that you should enter from the keyboard, sections of code, programming examples, and syntax examples. This font is also used for the proper names of disk drives, paths, directories, programs, subprograms, subroutines, device names, functions, operations, variables, filenames, and boldBold text in this font denotes the messages and responses that the computer automatically prints to the screen. This font also emphasizes lines of code that are different from the other examples.

National Instruments Corporation5 Getting Started with CompactRIO and LabVIEWO verview of the Application in this TutorialIn this tutorial, you will create VIs that can be used in control and industrial applications where you need to measure an input and produce an output. The input and output can be analog or digital. You will configure the DO module for pulse-width modulation and the DI module for period measurement. You will configure the AI module to receive a voltage input from the AO tutorial shows how to create the VIs using both programming modes, Scan Interface mode and FPGA Interface Up the HardwareComplete the following steps to set up the hardware for the application in this the controller on the chassis if you are not using an integrated controller and chassis.

9 Refer to the controller operating instructions for information about installing the the DO module in slot 1 of the chassis, the DI module in slot 2, the AO module in slot 3, and the AI module in slot the modules as follows. DO0 on the DO module to DI0 on the DI an external power supply to the DO module if it requires one. Refer to the module operating instructions for information about power AO0 on the AO module to AI0 on the AI to the module operating instructions for information about wiring and for specifications. If the voltage ranges or other attributes of the inputs and outputs make the modules unsuitable for wiring together, skip the module wiring and go to step 4. You can still complete and learn from the tutorial, but you will not be able to test the VI as described in the Deploying, Testing, and Using the VI in Scan Interface Mode the controller to a power supply and an Ethernet network on the same subnet as the development computer.

10 Refer to the controller operating instructions for information about wiring the controller to the power supply and Ethernet Started with CompactRIO and Software on and Configuring the ControllerComplete the following steps to configure the controller and install software on Measurement & Automation Explorer (MAX) on the development the controller under Remote Systems in the Configuration pane. If you do not see the controller, you may need to disable the firewall on the development default network behavior of an unconfigured controller depends on the revision of the controller. Refer to the controller operating instructions for more information about network that the Serial Number in the Identification section matches the serial number on the you do not want to format the disk on the controller, eliminating all installed software and files, power on the controller and skip to step the Safe Mode switch on the controller to the On on the controller.
