USING LOOPS This lesson presents the different ways that you can iteratively execute LabVIEW code and techniques for managing loop execution. In LabVIEW, VIs used within other VIs are called subVIs. You will learn how to build the icon and connector pane of a VI so that it can be used as a subVI. LabVIEW LabVIEW is systems engineering software for applications that require test, measurement, and control with rapid access to hardware and data insights. Required Software Download Academic Software , Learn About Software Licensing LabVIEW. This Express VI does not read ASCII files. Refer to Lesson 6, Managing File and Hardware Resources, for more No na information on reading data from a file. ti o Analyze Express VIs used for the Analyze Data task include the following—Amplitude and Level Measurements, Statistics, and Tone Measurements. Na Amplitude and Level Measurements The Amplitude and Level Measurements Express VI performs voltage measurements on a signal. These include DC, rms, maximum peak, minimum peak, peak to peak, cycle average, and cycle rms measurements.

This includes mean, sum, standard deviation, and extreme values. uti ts ri b e n Spectral Measurements on The Spectral Measurements Express VI performs spectral measurement on a waveform, such as magnitude and power spectral density. i st um Tone Measurements The Tone Measurements Express VI searches for a single tone with the highest frequency or r D str highest amplitude. It also finds the frequency and amplitude of a single tone. t fo l I n Filter The Filter Express VI processes a signal through filters and windows. Filters used include the following: Highpass, Lowpass, Bandpass, Bandstop, and Smoothing.

Windows used include Butterworth, Chebyshev, Inverse Chebyshev, Elliptical, and Bessel. No na Present ti o Present results by using Express VIs that perform a function, such as the Write to Measurement File Express VI, or indicators that present data on the front panel window. The most commonly used indicators for this task include the Waveform Chart, the Waveform Graph, and the XY Graph. Refer to Lesson 6, Managing File and Hardware Resources, for more information on writing to measurement files. uti ts ri b e n Build Text on The Build Text Express VI creates text, usually for displaying on the front panel window or exporting to a file or instrument. Refer to Lesson 6, Managing File and Hardware Resources, for i st um more information on creating strings. r D str Running a VI After you configure the Express VIs and wire them together, you can run the VI.

When you finish creating your VI, click the Run button on the toolbar to execute the VI. t fo l I n While the VI is running, the Run button icon changes to the figure shown below. After the execution completes, the Run button icon changes back to its original state, and the front panel indicators contain data. No na Run Button Errors ti o If a VI does not run, it is a broken, or nonexecutable, VI. The Run button appears broken when the VI you are creating or editing contains errors. Na If the button still appears broken when you finish wiring the block diagram, the VI is broken and cannot run. Generally, this means that a required input is not wired, or a wire is broken. Press the broken run button to access the Error list window. The Error list window lists each error and describes the problem. You can double-click an error to go directly to the error. Refer to Lesson 2, Troubleshooting and Debugging VIs, for more information on debugging VIs.

Sometimes a VI produces data or runs in a way you do not expect. You can use LabVIEW to configure how a VI runs and to identify problems with block diagram organization on or with the data passing through the block diagram. Correcting Broken VIs B. Debugging Techniques C. Undefined or Unexpected Data r D str D. Correcting Broken VIs If a VI does not run, it is a broken, or nonexecutable, VI. uti ts ri b e n If the button still appears broken when you finish wiring the block diagram, the VI is broken and cannot run. on Finding Causes for Broken VIs i st um Warnings do not prevent you from running a VI. They are designed to help you avoid potential problems in VIs. Errors, however, can break a VI.

You must resolve any errors before you can run the VI. Click the broken Run button or select View»Error List to find out why a VI is broken. The Error list window lists all the errors. The Items with errors section lists the names of all items in r D str memory, such as VIs and project libraries that have errors. If two or more items have the same name, this section shows the specific application instance for each item. The errors and warnings section lists the errors and warnings for the VI you select in the Items with errors section. The Details section describes the errors and in some cases recommends how to correct the errors.

Click the Help button to display a topic in the LabVIEW Help that describes the error in detail and t fo l I n includes step-by-step instructions for correcting the error. Click the Show Error button or double-click the error description to highlight the area on the block diagram or front panel that contains the error. Example of the Error List Dialog Box No na ti o Na ni. Refer to the Correcting Broken VIs topic of the LabVIEW Help for information about correcting broken wires. Refer to the Using Wires to Link Block Diagram ri b e n Objects topic of the LabVIEW Help for information about setting required inputs and outputs. Refer to the Creating SubVIs topic of the LabVIEW Help for information about subVIs. These parameters detect errors encountered in each node on the block diagram and indicate if and where an error occurred. You also can use these parameters in the VIs you build. Determine the causes and correct them in t fo l I n the VI.

VIs and functions pass default values if recommended or optional inputs are No na unwired. For example, a Boolean input might be set to TRUE if unwired. Unlike unwired functions, unwired VIs do not always generate errors unless you configure an input to be required. If you mistakenly place an unwired subVI on the block diagram, it executes when the block diagram does. Consequently, the VI might perform extra actions. This feature allows you to easily check values of data that last passed through any wire. This often happens with numbers.

For example, at one point in the VI an operation could have divided a number by zero, uti ts thus returning Inf infinity , whereas subsequent functions or subVIs were expecting numbers. Also, close subVI front panels and block diagrams when you are not using them because open windows can affect execution speed. For i st um example, you might wire a bit integer to a function that only accepts 8-bit integers. This causes the function to convert the bit integer to an 8-bit representation, potentially causing a loss of data. LabVIEW detects data type and cluster size mismatches at edit time, but it does not detect mismatches of elements of the same type. You inadvertently might have hidden a subVI by placing one directly on top of another node or by decreasing the size of a structure without keeping the subVI in view.

Also open the VI Hierarchy window to see the subVIs for a VI. To help avoid incorrect results caused by hidden VIs, specify that inputs to VIs are required. ti o Execution Highlighting View an animation of the execution of the block diagram by clicking the Highlight Execution button. Na Execution highlighting shows the movement of data on the block diagram from one node to another using bubbles that move along the wires. Use execution highlighting in conjunction with single-stepping to see how data values move from node to node through a VI. uti ts Note Execution highlighting greatly reduces the speed at which the VI runs. Example of Execution Highlighting in Use ri b e n on i st um r D str t fo l I n Single-Stepping Single-step through a VI to view each action of the VI on the block diagram as the VI runs.

The single-stepping buttons, shown as follows, affect execution only in a VI or subVI in single-step mode. No na Enter single-step mode by clicking the Step Into or Step Over button on the block diagram toolbar. Move the cursor over the Step Into, Step Over, or Step Out button to view a tip strip that ti o describes the next step if you click that button. You can single-step through subVIs or run them normally. When you single-step through a VI, nodes blink to indicate they are ready to execute. If you single-step through a VI with execution highlighting on, an execution glyph appears on the icons Na of the subVIs that are currently running.

uti ts Use the Probe tool if you have a complicated block diagram with a series of operations, any one of ri b e n which might return incorrect data. Use the Probe tool with execution highlighting, single-stepping, and breakpoints to determine if and where data is incorrect. If data is available, the probe on immediately updates and displays the data in the Probe Watch Window during execution highlighting, single-stepping, or when you pause at a breakpoint. When execution pauses at a node because of single-stepping or a breakpoint, you also can probe the wire that just executed to see the i st um value that flowed through that wire. Tip If you want a probe to display the data that flowed through the wire during the last VI execution, click the Retain Wire Values button on the block diagram toolbar.

r D str Types of Probes You can check intermediate values on a wire when a VI runs by using a generic probe, by using an indicator on the Controls palette to view the data, by using a supplied probe, by using a customized supplied probe, or by creating a new probe. t fo l I n Note MathScript RT Module You can view the data in a script in a MathScript Node as a VI runs by using a LabVIEW MathScript probe. Generic No na Use the generic probe to view the data that passes through a wire. Right-click a wire and select Custom Probe»Generic Probe from the shortcut menu to use the generic probe. The generic probe displays the data. You cannot configure the generic probe to respond to the data. ti o LabVIEW displays the generic probe when you right-click a wire and select Probe, unless you already specified a custom or supplied probe for the data type.

You can debug a custom probe similar to a VI. However, a probe cannot probe its own block diagram, nor the block diagram of any of its subVIs. When debugging probes, use the generic Na probe. Using Indicators to View Data You also can use an indicator to view the data that passes through a wire. For example, if you view numeric data, you can use a chart within the probe to view the data. Right-click a wire, select Custom Probe»Controls from the shortcut menu, and select the indicator you want to use. You also can click the Select a Control icon on the Controls palette and select any custom control or ni. LabVIEW treats type definitions as custom controls when you use them to view probed data. If the data type of the indicator you select does not match the data type of the wire you uti ts right-clicked, LabVIEW does not place the indicator on the wire.

Supplied ri b e n Supplied probes are VIs that display comprehensive information about the data that passes through a wire. For example, the VI Refnum Probe returns information about the VI name, the VI path, and on the hex value of the reference. You also can use a supplied probe to respond based on the data that flows through the wire. For example, use an Error probe on an error cluster to receive the status, code, source, and description of the error and specify if you want to set a conditional breakpoint if i st um an error or warning occurs. The supplied probes appear at the top of the Custom Probe shortcut menu. Right-click a wire and select Custom Probe from the shortcut menu to select a supplied probe. Only probes that match the data type of the wire you right-click appear on the shortcut menu. llb for an example of using supplied probes. Custom t fo l I n Use the Create New Probe dialog box to create a probe based on an existing probe or to create a new probe.

Right-click a wire and select Custom Probe»New from the shortcut menu to display the Create New Probe dialog box. Create a probe when you want to have more control over how LabVIEW probes the data that flows through a wire. When you create a new probe, the data type of the probe matches the data type of the wire you right-clicked. If you want to edit the probe you No na created, you must open it from the directory where you saved it. After you select a probe from the Custom Probe shortcut menu, navigate to it using the Select a Control palette option, or create a new probe using the Create New Probe dialog box, that probe becomes the default probe for that data type, and LabVIEW loads that probe when you right-click ti o a wire and select Probe from the shortcut menu.

LabVIEW only loads probes that exactly match the data type of the wire you right-click. That is, a double precision floating-point numeric probe cannot probe a bit unsigned integer wire even though LabVIEW can convert the data. Na Note If you want a custom probe to be the default probe for a particular data type, save the probe in the user. Do not save probes in the vi. uti ts ri b e n When you set a breakpoint on a wire, execution pauses after data passes through the wire and the Pause button appears red. Place a breakpoint on the block diagram to pause execution after all on nodes on the block diagram execute.

The block diagram border appears red and blinks to reflect the placement of a breakpoint. i st um When a VI pauses at a breakpoint, LabVIEW brings the block diagram to the front and uses a marquee to highlight the node, wire, or line of script that contains the breakpoint. When you move the cursor over an existing breakpoint, the black area of the Breakpoint tool cursor appears white. When you reach a breakpoint during execution, the VI pauses and the Pause button appears red. Suspending Execution Suspend execution of a subVI to edit values of controls and indicators, to control the number of No na times the subVI runs before returning to the caller, or to go back to the beginning of the execution of the subVI.

You can cause all calls to a subVI to start with execution suspended, or you can suspend a specific call to a subVI. ti o To suspend all calls to a subVI, open the subVI and select Operate»Suspend when Called. The subVI automatically suspends when another VI calls it. If you select this menu item when single-stepping, the subVI does not suspend immediately. The subVI suspends when it is called. To suspend a specific subVI call, right-click the subVI node on the block diagram and select SubVI Na Node Setup from the shortcut menu. Place a checkmark in the Suspend when called checkbox to suspend execution only at that instance of the subVI.

The VI Hierarchy window, which you display by selecting View»VI Hierarchy, indicates whether a VI is paused or suspended. An arrow glyph indicates a VI that is running regularly or single-stepping. ri b e n An exclamation point glyph indicates that the subVI is suspended. on i st um Note A VI can be suspended and paused at the same time. Determining the Current Instance of a SubVI When you pause a subVI, the Call list pull-down menu on the toolbar lists the chain of callers from r D str the top-level VI down to the subVI. Use the Call list menu to determine the current instance of the subVI if the block diagram contains more than one instance. When you select a VI from the Call list menu, its block diagram opens and LabVIEW highlights the current instance of the subVI.

t fo l I n You also can use the Call Chain function to view the chain of callers from the current VI to the top-level VI. Undefined or Unexpected Data No na Undefined data, which are NaN not a number or Inf infinity , invalidate all subsequent operations. LabVIEW does not check for overflow or underflow conditions on integer values. Overflow and Na underflow for floating-point numbers is in accordance with IEEE , Standard for Binary Floating-Point Arithmetic. Floating-point operations propagate NaN and Inf reliably. When you explicitly or implicitly convert NaN or Inf to integers or Boolean values, the values become meaningless. For example, dividing 1 by zero produces Inf. Converting Inf to a bit integer produces the value 32,, which appears to be a normal value. function to the value you suspect is invalid. uti ts Do not rely on special values such as NaN, Inf, or empty arrays to determine if a VI produces undefined data.

Instead, confirm that the VI produces defined data by making the VI report an error if it encounters a situation that is likely to produce undefined data. ri b e n For example, if you create a VI that uses an incoming array to auto-index a For Loop, determine what you want the VI to do when the input array is empty. Either produce an output error code, on substitute defined data for the value that the loop creates, or use a Case structure that does not execute the For Loop if the array is empty. Error Handling No matter how confident you are in the VI you create, you cannot predict every problem a user can encounter.

Without a mechanism to check for errors, you know only that the VI does not work properly. Error checking tells you why and where errors occur. r D str Error handling is the mechanism for anticipation, detection, and resolution of warnings and errors. Error handling is an essential component in your LabVIEW application development. With error handling you quickly pinpoint the source of programming errors. Without it, you might observe t fo l I n unexpected behavior but struggle to find the source of the problem. Error handling is also extremely valuable when you test your application to ensure that your error reporting is meaningful and that the error handling code safely stops your application when an error occurs. For example, during stress testing you are setting values or conditions that are beyond the normal operational capacity of your application which often result in errors.

When such errors occur, you want to ensure proper shutdown of your application. No na Error handling continues to be important after an application is deployed. Error handling can help detect system and environment differences—such as differences in file systems, memory, and disk resources. National Instruments strongly recommends using error handling. ti o Automatic Error Handling By default, LabVIEW automatically handles any error when a VI runs by suspending execution, highlighting the subVI or function where the error occurred, and displaying an error dialog box. In Na the error dialog box, each error has a numeric code to identify it and a corresponding error message to display to the user. To disable automatic error handling for the current VI, select File»VI Properties and select Execution from the Category pull-down menu. To disable automatic error handling for any new, blank VIs you create, select Tools»Options and select Block Diagram from the Category list. To disable automatic error handling for a subVI or function within a VI, wire its error out parameter to the error in parameter of another subVI or function or to an error out indicator.

You also might want the VI to retry for a certain period of time. For example, if LabVIEW encounters an error, you can display the on error message in different kinds of dialog boxes. For example, when an error is detected you can fix the error programmatically and then wire the error out output of the VI or function to the error in input of the Clear Errors VI. Tip Use error handling in conjunction with the debugging tools to find and manage errors. r D str Error Clusters VIs and functions return errors in one of two ways—with numeric error codes or with an error cluster.

Typically, functions use numeric error codes, and VIs use an error cluster, usually with error t fo l I n inputs and outputs. Use the error cluster controls and indicators to create error inputs and outputs in subVIs. Tip All error clusters on a block diagram typically provide the same standard error in and standard error out functionality. A nonzero error code ti o coupled with a status of FALSE signals a warning rather than a error. Errors Na An error is defined as an error cluster with a status value of TRUE, regardless of the code value. If LabVIEW detects an error, the node passes the error to the next node without executing that part of the code.

Although most errors have negative code values and warnings have positive code values, this is not universally true. Therefore you should rely on both the status value and the code value to detect uti ts errors and warnings. Warnings are typically considered less severe than errors. Some APIs and functions, such as the ri b e n Match Regular Expression function, only report errors. However, other APIs, such as the VISA API for controlling stand-alone instruments, often reports warnings. on Unlike when an error occurs, nodes execute normally when LabVIEW detects a warning. Even though code executes normally, it is important that you monitor warnings during development to i st um ensure proper behavior of your application. Explain Error Dialog Box When an error occurs, right-click within the cluster border and select Explain Error from the shortcut menu to open the Explain Error dialog box.

The Explain Error dialog box contains r D str information about the error. The shortcut menu includes an Explain Warning option if the VI contains warnings but no errors. You also can access the Explain Error dialog box from the Help»Explain Error menu. t fo l I n Detect and Report Errors Error handling in LabVIEW follows the dataflow model. Just as data values flow through a VI, so can error information. To implement good error handling, you must determine the actions to take when an error occurs at No na any point in your application. To begin with, you must utilize the error terminals on functions and VIs. Since the error cluster is implemented as a flow-through parameter, you should propagate errors by wiring the error out cluster of the first node you want to execute to the error in cluster of the next node you want to execute. You must continue to do this for sequences of nodes. ti o As the VI runs, LabVIEW tests for errors at each node.

If LabVIEW does not find any errors, the node executes normally. If LabVIEW detects an error or warning, the node passes the error to the next node. Any subVIs that you create should also implement this flow-through behavior. Refer to Figure for proper use of the shift-register to propagate errors and uti ts warnings to successive loop iterations. Use Shift Registers to Propagate Errors and Warnings ri b e n on i st um Merging Errors and Warnings Use the Merge Error function to merge the error out cluster values from parallel sequences. Refer to Figure for an example of merging error information from parallel node sequences. r D str Figure Merge Errors From Multiple Sources t fo l I n No na At the end of your application after all error sources are merged into one error cluster, you must report errors to the user using the Simple Error Handler VI or another error reporting mechanism.

Simple Error Handler VI ti o By default, the Simple Error Handler VI displays a dialog with a description of any errors that occurred and does not report warnings. However, the Simple Error Handler VI can be configured for other error handling behavior. This is useful if you want to have programmatic control Na over handling errors. After the user acknowledges the dialog box, the VI returns control to the main VI. If the user selects Stop, the VI calls the Stop function to halt execution. If the user selects Stop, the VI calls the Stop function to uti ts halt execution. Ranges of Error Codes ri b e n VIs and functions in LabVIEW can return numeric error codes.

Each product or group of VIs on defines a range of error codes. Refer to the Ranges of LabVIEW Error Codes topic of the LabVIEW Help for error code tables listing the numeric error codes and descriptions for each product and VI grouping. i st um In addition to defining error code ranges, LabVIEW reserves some error code ranges for you to use in your application. You can define custom error codes in the range of — through —, through , or , through , Some numeric error codes are used by more than one group of VIs and functions. For example, r D str error 65 is both a serial error code, indicating a serial port timeout, and a networking error code, indicating that a network connection is already established. Which of the following will result in a broken run arrow? uti ts a. A subVI is broken b. The diagram includes a divide by zero c. A required subVI input is unwired ri b e n d. A Boolean terminal is wired to a numeric indicator on i st um 2.

All errors have negative error codes and all warnings have positive error codes. True b. False No na 4. Merge Errors function concatenates error information from multiple sources. Which of the following are the contents of the error cluster? These skills include designing a user ri b e n interface, choosing a data type, documenting your code, using looping structures such as While Loops and For Loops, adding software timing to your code, displaying your data as a plot, and on making decisions in your code using a Case structure.

Front Panel Basics In the design phase of the software development method, you identify the inputs and outputs of the problem. This identification leads directly to the design of the front panel window. You can display the outputs of the problem with indicators, such as graphs, charts, or LEDs, or log the outputs to a file. You also can output data to a device using signal generation. Designing Controls and Indicators r D str When choosing controls and indicators, make sure that they are appropriate for the task you want to perform. For example, when you want to determine the frequency of a sine wave, choose a dial control, or when you want to display temperature, choose a thermometer indicator. t fo l I n Labels Make sure to label controls and indicators clearly.

These labels help users identify the purpose of each control and indicator. Also, clear labeling helps you document your code on the block diagram. Control and indicator labels correspond to the names of terminals on the block diagram, as shown in Figure No na Figure Front Panel Controls and Indicators Appear on Block Diagram ti o Na 1 Front Panel Window 2 Block Diagram ni. Figure shows the Upper Temperature control with a default value of 35 °C. By setting a default value, you can assume a reasonable value for a VI if the user does not set another value during run-time. uti ts Complete the following steps to set the default value of a control or indicator: 1. Enter the desired value. Right-click the control or indicator and select Data Operations»Make Current Value Default from the shortcut menu. Setting Default Values i st um r D str t fo l I n No na Tip You can also reinitialize values to their default values.

ti o Tip To initialize or re-initialize all controls and indicators on the front panel at the same time, select Edit»Make Current Values Default or Edit»Reinitialize to Default Values from the LabVIEW menu. LabVIEW Data Types Many different data types exist for data. You already learned about numeric, Boolean, and string data types in Lesson 1, Navigating LabVIEW. Other data types include the enumerated data type, dynamic data, and others. Even within numeric data types, there are different data types, such as whole numbers or fractional numbers. For example, in Figure , Height cm is a double-precision, floating-point numeric. This is indicated by the color of the terminal, orange, and by the text shown uti ts on the terminal, DBL. Terminal Data Type Example ri b e n on i st um Tip Terminal names correspond to the labels of the controls and indicators on the front panel.

Right-click a terminal and select Find control or Find indicator from the shortcut r D strmenu to locate the control or indicator on the front panel. Shortcut Menus All LabVIEW objects have associated shortcut menus, also known as context menus, pop-up menus, and right-click menus. As you create a VI, use the shortcut menu items to change the t fo l I n appearance or behavior of front panel and block diagram objects. To access the shortcut menu, right-click the object. Figure shows a shortcut menu for a control and terminal. Shortcut Menus for Front Panel and Block Diagram Objects No na ti o Na ni. Right-click an object and select Properties from the shortcut menu to access the property dialog box for an object. Figure shows the property dialog box for the Height cm terminal uti ts shown in Figure The options available on the property dialog box for an object are similar to the options available on the shortcut menu for that object.

Property Dialog Box for a Numeric Terminal on i st um r D str t fo l I n No na You can select multiple objects on the front panel or the block diagram and edit any properties the objects share. Right-click an object from the selection and select Properties from the shortcut menu to display the Properties dialog box. The Properties dialog box only displays tabs and properties that the objects you select share. Select similar objects to display more tabs and properties. If you select objects that do not share any common properties, the Properties dialog box does not display any Na tabs or properties. To change the representation type of a number, right-click the control, indicator, or constant, and select Representation, as shown in Figure Numeric Representation ri b e n on i st um r D str t fo l I n No na ti o When you wire two or more numeric inputs of different representations to a function, the function usually returns the data in the larger, or wider, representation.

The functions coerce the smaller representations to the widest representation before execution. LabVIEW places a coercion dot on the terminal where the conversion takes place. Refer to Numeric Conversion for more information. Na The numeric data type includes the following subcategories of representation—floating-point numbers, signed integers, unsigned integers, and complex numbers. In LabVIEW, floating-point numbers are represented with the color orange. uti ts Single-precision SGL —Single-precision, floating-point numbers have bit IEEE single-precision format. Use single-precision, floating-point numbers when memory savings are important and you will not overflow the range of the numbers ri b e n Double-precision DBL —Double-precision, floating-point numbers have bit IEEE on double-precision format.

Double-precision is the default format for numeric objects. For most situations, use double-precision, floating-point numbers i st um Extended-precision EXT —When you save extended-precision numbers to disk, LabVIEW stores them in a platform-independent bit format. In memory, the size and precision vary depending on the platform. Use extended-precision, floating-point numbers only when necessary. The performance of extended-precision arithmetic vary among platforms. r D str Fixed-Point Data Type The fixed-point data type is a numeric data type that represents a set of rational numbers using binary digits, or bits. Unlike the floating-point data type, which allows the total number of bits LabVIEW uses to represent numbers to vary, you can configure fixed-point numbers to always use t fo l I n a specific number of bits.

Hardware and targets that only can store and process data with a limited or fixed number of bits then can store and process the numbers. You can specify the range and precision of fixed-point numbers. Note To represent a rational number using the fixed-point data type, the denominator of the rational number must be a power of 2, because the binary number system is a No na base-2 number system. and other countries.
