Refer to the specific RT target hardware documentation for information about which RTOS your RT target uses.•NI Linux Real-Time •Phar Lap ETS •VxWorksInstalling Japanese and Simplified Chinese Languages After you install the Real-Time Module on your development computer, you can complete the following steps to install and use Japanese and Simplified Chinese languages on an RT target:e the LabVIEW Real-Time Software Wizard in NI Measurement & AutomationExplorer (NI MAX) to install the Language Support for Japanese or Language Support for Simplified Chinese software component on the RT target. Refer to the Measurement & Automation Explorer Help for information about the LabVIEW Real-Time Software Wizard.2.Open the System Settings tab and select Japanese or Simplified Chinese as the Locale .Note You cannot use Japanese or Simplified Chinese characters in directory names or file names on the RT target.Activating the Real-Time ModuleThe Real-Time Module relies on licensing activation. When the evaluation period expires, you must activate a valid Real-Time Module license to continue using the Real-Time Module. You must create an User Profile to activate your software.You can use the NI License Manager, available by selecting Start»All Programs»National Instruments»NI License Manager , to activate National Instruments products. (Windows 8)Click NI Launcher and select NI License Manager in the window that appears. Refer to the National Instruments License Manager Help , available by selecting Help»Contents in the NI License Manager, for information about activating NI products.Configuring Real-Time TargetsUse NI MAX to configure RT targets and to install software and drivers on targets. You can install NI MAX from the LabVIEW Platform media.•Networked RT Targets —Refer to the MAX Remote Systems Help book in theMeasurement & Automation Explorer Help , available by selecting Help»MAX Help from MAX, for information about configuring networked RT targets.•Desktop PC Targets —Refer to the Using Desktop PCs as RT Targets with theLabVIEW Real-Time Module document for information about configuring a desktop PC as a networked RT target. Open the labview\manuals directory and double-click RT_Using_PC_as_RT_Target.pdfto open the document.Note If you install NI Web-based Configuration & Monitoring on an RT target, Array you can use a web browser to perform common monitoring and configuration taskson the target. Select Fundamentals»Working with Projects and Targets»How-To»Monitoring and Configuring a Remote Device from a Web Browseron the Contents tab in the LabVIEW Help for information about NI Web-basedConfiguration & Monitoring.New FeaturesThe LabVIEW 2014 Real-Time Module includes the following new features. Refer to theLabVIEW Help, available by selecting Help»LabVIEW Help, for more information about thesefeatures.Embedded User Interface on RT T argetsThe LabVIEW 2014 Real-Time Module includes support for an embedded UI on selectNI Linux Real-Time targets. The embedded UI provides a graphical working environment withadvanced display capabilities. For example, you can connect a display device to the RT targetusing a DisplayPort connection, and then display the front panel of a VI running on the RTtarget. In contrast, other RT targets run headless, with only a basic console output display. Real-Time T race ViewerThe LabVIEW 2014 Real-Time Module includes the Real-Time Trace Viewer. Prior releases ofthe LabVIEW Real-Time Module packaged the Real-Time Trace Viewer as a separate toolkit(Real-Time Execution Trace Toolkit). You can use the Real-Time Trace Viewer to capture thetiming and execution data of VI and thread events for applications running on an RT target. TheReal-Time Trace Viewer displays the timing and event data, or trace session, on the hostcomputer. In LabVIEW, select Tools»Real-Time Module»Trace Viewer to display theReal-Time Trace Viewer.Establishing Modbus Communication Using Modbus VIs The LabVIEW 2014 Real-Time Module includes the Modbus palette, available on the Data Communication palette. You can use the Modbus VIs to build control systems with specific performance and rate requirements. By using the Modbus VIs, you can control the requests that Modbus masters generate, determine when to send these requests, and operate on the responses that you receive from Modbus slaves.Ethernet over USBThe LabVIEW 2014 Real-Time Module includes support for connecting myRIO and selectNI Linux Real-Time targets to your host computer using a USB device connection. The USBconnection is an alternative to an Ethernet connection, allowing you to configure, develop for,and deploy to your RT target using a virtual Ethernet port over USB.4||LabVIEW Real-Time Module Release and Upgrade NotesUSB 3.0 SupportThe LabVIEW 2014 Real-Time Module includes support for USB 3.0 on select NI Linux Real-Time targets. You can connect compatible devices such as USB 3.0 cameras to your RT target to benefit from increased streaming speeds and higher simultaneous device connections. Intel® Atom™ Dual Core Processor Support on NI Linux Real-Time T argetsThe LabVIEW 2014 Real-Time Module includes support for new NI Linux Real-Time targets equipped with Intel x64 processors. These RT targets support the embedded UI and provide additional memory to better handle data-intensive applications.12-Core CPU Support on Phar Lap ETS T argetsThe LabVIEW 2014 Real-Time Module includes support for CPUs with up to 12 cores on Phar Lap ETS targets. Previously, these targets only supported CPUs with up to eight cores.

初识LabVIEW入门指南LabVIEW（Laboratory Virtual Instrument Engineering Workbench）是一款由美国国家仪器公司（National Instruments）推出的图形化编程环境和开发平台，为工程师和科学家提供了一个强大的工具，用于设计、控制和测量各种仪器和设备。

LabVIEW的独特之处在于其图形化编程语言，使得编程变得更加直观和易于理解。

本指南将介绍初学者如何入门LabVIEW，帮助读者快速上手和了解LabVIEW的基本概念和使用方法。

一、LabVIEW的界面和基本概念LabVIEW的界面分为两部分：前面板和代码编辑器。

前面板是用户与程序交互的界面，通过拖拽控件和指示器来搭建用户界面。

代码编辑器用于编写LabVIEW程序的代码，在代码编辑器中用户可以创建流程图、定义变量和函数等。

LabVIEW的基本概念包括虚拟仪器（Virtual Instrument）和数据流图（Dataflow Diagram）。

虚拟仪器是用来模拟实际仪器和设备的软件模块，包括输入控件、输出指示器和中间处理节点。

数据流图则是用于描述程序的执行流程，程序按照数据从一个节点流向另一个节点的方式来执行。

二、LabVIEW的数据类型和变量LabVIEW支持多种数据类型，包括数字、字符串、布尔值、数组等。

通过数据类型的选择，可以更好地处理和处理不同类型的数据。

在LabVIEW中，变量是用来存储和传递数据的载体，可以通过给变量赋值和读取变量的值来实现数据在程序中的传递和处理。

三、LabVIEW中的控制结构和函数模块LabVIEW提供了丰富的控制结构和函数模块，用于实现数据的处理和流程控制，如循环结构、条件结构、选择结构、函数节点等。

通过这些控制结构和函数模块，可以构建复杂的程序逻辑和算法。

四、LabVIEW的应用领域LabVIEW广泛应用于各个领域，包括自动化控制、测量与测试、数据采集与处理、图像处理、信号处理等。
