Loop timing refers to how long a loop takes to execute a single iteration. The amount and type of code a loop contains affects its execution speed. By default, each loop iteration executes as quickly as ...

What to Use Open/Create/Replace File A read or write node from the Storage palette category Close File What to Do Create the following diagram to programmatically open, write to, and close a text file. ...

Instead of creating the same code on a diagram multiple times, you can write code in a single location and use a For Loop to programmatically repeat it. For example, you might want to read a specific number ...

While working with an array of data, you might want to access individual elements within the array. Although you can use a combination of Array nodes to accomplish this task, the For Loop includes an auto-indexing ...

You can save and analyze the data that a device or code generates in a variety of ways. Viewing data in different formats can provide insight into trends or outliers in the data. What to Use An application ...

Executes its subdiagram n times. The iteration terminal provides the current loop iteration count, which ranges from 0 to n-1. DAQExpress does not support FPGA devices Supported in VIs that run in a web ...

Repeats the code on its subdiagram until a specific condition occurs. A While Loop always executes at least one time. A While Loop behaves similarly to a do while loop in other programming languages. DAQExpress ...

To develop an API to distribute to other users that is consistent with NI style recommendations for G content, refer to the following best practice guidelines: File Organization and Node Naming Component ...

In some situations, you might know that you want to repeat an operation, but you do not know exactly how many times you want to repeat that operation. Instead, you know only that the operation should repeat ...

By default, each loop iteration executes as quickly as possible based on the code inside the loop. However, consider a program that includes multiple loops that contain code requiring different amounts ...

Compare elements when you want to compare the individual corresponding elements of the input arrays or clusters. Compare aggregates when you want to compare the input arrays or clusters in their entirety. ...

By default, each loop iteration executes as quickly as possible based on the code inside the loop. However, you might want to control the rate at which a loop executes in order to specify a fixed time ...

To turn an existing VI into a subVI, use the icon editor to assign input and output terminals and to customize the appearance of the subVI node. What to Do Select EditIcon and connector pane to display ...

Hyperbolic Trigonometry Nodes (G Dataflow) DAQExpress 1.0 DAQExpress 2.0 DAQExpress 2.1 DAQExpress 3.0 DAQExpress 3.1 DAQExpress 3.3 DAQExpress 4.0 DAQExpress 4.1 DAQExpress 5.0 DAQExpress 5.1 Hyperbolic ...

Computes the cross correlation of two signals. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application Algorithm for Calculating the Cross Correlation The cross correlation ...

Performs statistical calculations on a signal. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application signal The input signal. This input supports the following data ...

Generates a signal containing a sine wave. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application Algorithm for Simulating a Sine Wave If sequence Y represents a sine ...

G Dataflow (G) is a graphical programming language in which nodes on a diagram execute when data is available for all required inputs. A node in G Dataflow executes only when it receives data for all wired ...

A state machine has four components on the diagram: a While Loop, a Case Structure, an Enum constant, and a shift register. While Loop—Sets the outer boundary for the state machine code and facilitates ...

Use a Case Structure to incorporate decision logic into your program. A Case Structure contains one or more subdiagrams, or cases, exactly one of which executes when the structure executes. Case Structures ...

Group data elements of a mixed type that logically belong together. What Is a Cluster? Clusters group data elements of mixed types. A cluster is similar to a record or a struct in text-based programming ...

A loop is a programming element that executes the same code multiple times, or iterations. Types of Loops Loop Behavior Example Diagram For Loop Repeats the code inside the loop for a set number of iterations. ...

Parsing a string into smaller pieces allows you to perform operations on individual words or groups of characters in the string. These words or groups of characters are often referred to as tokens. A token ...

A shift register passes values from one loop iteration to the next, but sometimes you need to access values from more than just the previous iteration. You can use stacked shift registers to store values ...

When you design a state machine, create a distinct initialize state and shutdown state for the program. You can also add a specific state to handle user input or provide custom error handling, depending ...

To keep track of every state and interaction in your program, design a state diagram of your state machine before you start programming. A state diagram is an illustration of all the states in a state ...

You can use the state machine design pattern to implement decision making algorithms where a set of distinguishable states exists. These states, or subdiagrams of code, carry out specific operations within ...

Factors like inefficient memory use, poorly designed panels, and too many I/O calls can negatively affect the execution speed of your VI. However, there are several strategies you can use to ensure that ...
