LabVIEW Fundamentals: Key Concepts

• Maintenance

  Maintenance is the ongoing process of resolving programming errors. Maintenance is defined as continuing to resolve issues as they arise.

• Testing

  Make sure to test your implementation with data that is both logical and illogical for the solution you created. Testing logical data verifies that the inputs produce the expected result. By testing illogical data, you can test to see if the code has effective error handling.

• Problem Solving

  Problem-solving skills are essential to creating solutions in LabVIEW. Making a program is usually about solving a problem. If the programmer has sub-par problem-solving skills, they will have a difficult time creating efficient code.

• Flow Charts and Decisions

  Which flow chart block is associated with a decision: an action or process, start and end, or data?

• State Transition Diagrams

  A state transition diagram is a specific type of flowchart that is commonly used when creating LabVIEW state machines.

• Design Process Steps

  Which of the following is not a step in the design process? Define the problem. Defining the problem is listed as a part of the software development method, not the design process. All other options are defined in the manual as being parts of the design process.

• Karaoke User Interface

  A karaoke user interface is developed that lets a user add their name and the song they want to sing to a queue. The interface displays the singer and song that is next in line. Identify the inputs: The inputs to this system are the name of the user and their song. Identify the outputs: The output of the system is the next singer and their song.

• Inputs

  The inputs indicate the raw data you want to process during the problem-solving process.

• Outputs

  The outputs represent the result of the calculation, processing, or other condition that the problem-solving procedure implements.

• Implementation Stage

  In the implementation stage, you create code for your algorithm. Displaying an algorithm as a flowchart is a good way to translate an algorithm into code. During implementation, you translate an algorithm into code. Because LabVIEW is a graphical programming language, working from a flowchart is a good way to translate an algorithm into LabVIEW code.

• State Transition Diagram Implementation

  The implementation of a state transition diagram requires which of the following: converting states and transitions to code, breaking down each state into its elements.

• Alarm System Example

  An alarm system measures wind speed and direction every 30 seconds and gives a signal indicating when the wind speed from the north is above 30 miles per hour. When are the inputs to this alarm system? The inputs are the wind speed, direction, and the alarm limit. What are the outputs to this system? The expected output is the alarm signal. Other potential answers may include the wind speed and direction, if additional processing of the wind speed and direction occurs elsewhere. What is the relationship between the inputs and outputs of this system? The signal output will be true when the wind speed and direction are above 30MPH and northerly, respectively. This signal will be processed every 30 seconds.

• Curing Material in a Furnace

  Assume you must cure a material at a certain temperature for a set amount of time in a furnace. The exact temperature will be recorded along with the exact amount of time the metal remains in the furnace. The elements of the problem are only the cure time and temperature.

• Software Development Steps

  Defining the problem, designing the algorithm, implementing the design, testing and verifying the implementation, maintaining and updating the implementation.

• LabVIEW Definition

  LabVIEW: Laboratory Virtual Instrumentation Engineering Workbench

• What is a VI?

  What is a VI and what does it mean with respect to LabVIEW? VI stands for Virtual Instrumentation. Computers can simulate the functionality of instruments virtually via software, using LabVIEW.

• Parts of a LabVIEW VI

  Front Panel, Block Diagram, and Icon/Connector Pane are the three parts of a LabVIEW VI.
