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 ...

Resamples a signal according to specific delay and sampling interval. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application reset A Boolean that specifies the initialization ...

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 ...

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. ...

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 ...

Computes the auto-correlation of a signal. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application Algorithm for Calculating the Auto-Correlation The auto-correlation ...

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 ...

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 ...

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 ...

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 ...

Select the section of code you want to reuse. Click EditCreate subVI from selection. This generates a new .gvi file in the project. You can open this file by double-clicking the corresponding subVI node ...

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 ...

By default, each call to the subVI is executed one after another. This may cause your application to execute slowly or have unexpected behavior. To allow multiple calls to a subVI to execute simultaneously, ...

Group data elements of the same type. An example of a simple array is a 1D text array that lists the eight planets of our solar system in order. Array elements are ordered. An array uses an index so you ...

Multiple programming languages are available to accommodate your programming needs. LanguageDescription G Dataflow (G) A graphical language in which data flows from left to right through wires and nodes. ...

Chart numeric data by displaying a history of values. How is Charting Different Than Plotting? Graphs and charts differ in the way they display and update data. VIs with a graph usually collect the data ...

Chart and plot data. What Is the Difference between Graphs and Charts? You can collect data, usually in an array, and then plot the data to a graph. This process is similar to a spreadsheet that first ...

Returns the sum of all of the elements in a numeric array. DAQExpress does not support FPGA devices Supported in VIs that run in a web application numeric array An array of any number of dimensions. This ...

Group elements of various data types as rows on a table. The data grid control is a 1D array of clusters. Each row of the table is one cluster, and each element in a cluster represents one column. You ...

Computes the logical AND of the inputs. If all inputs are True, this node returns True. Otherwise, it returns False. This node performs bitwise operations on numeric inputs. DAQExpress does not support ...

Returns the maximum and minimum values found in an array, along with the indexes for each value. DAQExpress does not support FPGA devices Supported in VIs that run in a web application array An n-dimensional ...

Group and organize controls and indicators. When Should I Use a Tab Control? Tab controls are useful when you have several panel objects that are used together or during a specific phase of operation. ...

Returns the number of elements in each dimension of an array. DAQExpress does not support FPGA devices Supported in VIs that run in a web application Diagram Panel Indicator Comments size(s) for 1D Array ...

Create a list that a user can cycle through to make selections. Types of Selector Controls Types of Selector Controls Control Description Ring A ring control is a numeric input that presents a set of choices ...

Create text entry boxes and labels or enter or return the location of a file or directory. Which Text Control Should I Use? Use Control Enter string data. String Control Display string data. String Indicator ...

The following image is an example of a one-dimensional numeric array control. Index display—Determines which element to display at the top of the array control. An array index is zero-based. Element display—Value ...
