Most LabVIEW applications run on a general-purpose operating system (OS) likeWindows, Linux, Solaris, or Mac OS. Some applications require deterministic real-time performance thatgeneral-purpose operating systems cannot guarantee. The LabVIEW Real-Time Module extends thecapabilities of LabVIEW to address the need for deterministic real-time performance.This course assumes you have a level of experience with LabVIEW equivalent to completing the materialin the LabVIEW Core 1 course. In addition, you should be familiar with the Windows operating system andcomputer components such as the mouse, keyboard, connection ports and plug-in slots, and have experiencewriting algorithms in the form of flowcharts or block diagrams. The course and exercise manuals are dividedinto lessons, described as follows.In the course manual, each lesson consists of the following: An introduction that describes the purpose of the lesson and what you will learn A description of the topics in the lesson A summary quiz that tests and reinforces important concepts and skills taught in the lessonIn the exercise manual, each lesson consists of the following: A set of exercises to reinforce topicsC. What You Need to Get StartedBefore you use this course manual, make sure you have the following items: Computer running Windows 7/Vista/XP/2000 LabVIEW Full Development System version 2010 or later LabVIEW Real-Time Module version 2010 or later Temperature Chamber including a 12 volt fan, lamp, and a J-type thermocoupleLabVIEW Real-Time 1 Exercisesvini.com
