LabVIEW Core II : 2 days

Day 1

Planning LabVIEW Applications
This lesson describes some of the issues involved when developing LabVIEW applications, including the design process, the organization of subVI components, and the process of combining those components to create a complete application. This lesson also describes common LabVIEW programming architectures along with some tools to help you build VIs. Topics include:

• Design process overview and implementing large LabVIEW applications
• Choosing the right programming architecture for your application
• Creating menus with Boolean clusters
• Creating VIs from templates 

VI Design Techniques
This lesson describes good techniques for designing and building VIs. The techniques discussed include an overview of user interface design issues, good block diagram construction and wiring techniques, error handling, and an overview of LabVIEW run-time menus. All these techniques are important as you design and build more involved and complex VIs. Topics include

• Basics of user interface design
• Good programming techniques when creating modular, reusable block diagrams
• Using proper documentation conventions
• Implementing error handling in LabVIEW
• Learning how to organize development files in an easy to use hierarchy
• Using Sequence Structures to control program execution
• Learning how to develop an application that uses Run-Time Menus 

Object Properties
This lesson describes the use of object properties to modify front panel objects. Properties you can modify include color, size, position, behavior, and more. The first part of the lesson focuses on properties for simple front panel objects. The second part of the lesson describes properties associated with graphs and charts. Finally, this lesson describes control references and their advantages in modifying properties from subVIs. Topics include:

• Programmatically controlling the user interface with property nodes
• Customizing charts and graphs with property nodes
• Using control references to change properties from subVIs
• Using Type Definitions to create data types that can be easily modified and reused

 

Local and Global Variables
This lesson describes techniques for passing data without the use of wires. This concept is powerful and must be used carefully in VIs. The first section of this lesson discusses data management. Local variables are then introduced, followed by global variables. The end of the lesson describes when variables should and should not be used in VIs. Topics include:

• Implementing local and global variables to pass data within a VI and between VIs
• Understanding when variables are appropriate for use in a VI 

Advanced File I/O Techniques
In the LabVIEW Basics I course you learned the fundamentals of file I/O. This lesson describes advanced file I/O techniques. For example, one data format may have advantages over a different data format for your application. In addition, you may need to optimize the speed of your file I/O operations. Both the data format and the structure of your file I/O routines affect speed, so careful planning may be required. This lesson provides the in-depth understanding required for effective, flexible file I/O operations. Topics include:

• Understanding byte stream file types
• Storing data in binary file formats
• Retrieving data in a random access file format
• Creating your own file formats with Datalog type file input/output 

Project Management
This lesson describes some of the issues involved when building larger LabVIEW projects, including the design process, the organization of subVI components, and the process of creating a complete application. Topics include:

• Assembling your LabVIEW application
• Using the project management features built into LabVIEW 

Remote Data Management
This lesson describes the capabilities built into LabVIEW that allow you to easily work with networks. You can pass data between LabVIEW VIs on interconnected computers, and control VIs running on one computer from another computer. LabVIEW provides the high-level tools needed to make these interconnections so you can acquire, analyze, and present data from anywhere in your business. Topics include:

• Transferring data over networks using DataSocket technology
• Using the LabVIEW Web Server to display information remotely
• Viewing and controlling a running LabVIEW application remotely from LabVIEW and a Web browser.
