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 ...

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. ...

A red coercion dot appears on the node input where the coercion takes place. In the following diagram, a red coercion dot appears on the Add node because the node expects two inputs of matching numeric ...

Select the section of code you want to reuse. Click EditCreate subVI from selection to generate a new .gvi file in the project. To open this file, double-click the corresponding subVI node that contains ...

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, ...

Calculates single-shot AC, DC, and RMS values of a signal. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application reset A Boolean that specifies whether to reset the ...

Performs peak amplitude measurement. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application signal Input signal. This input accepts the following data types: waveform ...

Filters a signal using a Butterworth bandpass filter. Bandpass filters pass a certain band of frequencies. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application reset ...

Finds the continuous histogram of a signal. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application The following illustration shows the waveform of an input signal. ...

Subtracts 1 from the input value. DAQExpress does not support FPGA devices Supported in VIs that run in a web application Behavior for Enum Data All arithmetic functions except Increment and Decrement ...

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 ...

Adds 1 to the input value. DAQExpress does not support FPGA devices Supported in VIs that run in a web application Behavior for Enum Data All arithmetic functions except Increment and Decrement treat enum ...

Searches a string for the next token, where a token is defined as either the next set of characters that appears before a specified delimiter or as one of a specified set of operators. DAQExpress does ...

Returns one of two specified values depending on a Boolean value. DAQExpress does not support FPGA devices Supported in VIs that run in a web application true value Value that this node returns if selector ...

Waits until the value of the operating system's timer becomes a multiple of a specified amount of time. Use this node to synchronize activities.

You can use a duplicated output terminal to write to an indicator at multiple places on the diagram. You can also use a duplicated input terminal to read from a control at multiple places on the diagram. ...

Data in a control flows from the panel to the diagram through a corresponding input terminal. Data in an output terminal flows from the diagram to the panel through a corresponding indicator. The following ...

Terminals transfer data between the diagram and other VIs via subVIs. The following image shows the flow of data between terminals of the calling VI and a subVI. The calling VI passes data to the Percentage ...

Terminals transfer data between the diagram and panel, between the diagram and other nodes, or between duplicates of the same terminal on the diagram. As the following example shows, the color and symbol ...

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 ...

Locate or place one of the following analysis nodes on the diagram of a VI. Analysis FunctionDescription Amplitude Measurements Performs peak amplitude measurement. Curve Fit Finds the line that best represents ...

When looking for a problem in your code, you may have an idea of the general area where the problem exists. To help focus on this area, you can use a breakpoint to pause the VI at a specified point in ...

When the results of your application are not what you expect, you can use a set of tools to determine where errors occur within your code. Although errors are often detected automatically, sometimes your ...

After a loop completes a single iteration, sometimes you want to use the value of one of its calculations in the next loop iteration. You can use a shift register to pass data from the most recent iteration ...

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 ...

On the Document tab, in the Behavior section, click Properties to access VI Reentrancy options for your subVI. In the resulting dialog box, select the Execution tab. Choose one of the following options: ...

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 ...
