LabView 6i

Engineers can use the LabVIEW 6i development environment to take advantage of the Internet in their design processes. Its Player browser plug-in, measurement intelligence, and other features are crafted to increase productivity and enhance collaboration.Designers can share test results and measurement data with colleagues on site and around the world with LabVIEW 6i's built-in Internet tools. They can publish or subscribe to data with no programming. Additionally, they can continuously stream live data from any user interface control to the web or other applications just by clicking the mouse. This environment makes it easy to distribute measurement applications throughout an enterprise as well. Meanwhile, the LabVIEW Player browser plug-in lets users instantly access virtual instruments (VIs) from their web browser. Designers can create VIs and then distribute the applications to colleagues via the Internet. This plug-in is available for free from the company's web site. Also, LabVIEW 6i includes measurement intelligence, which is the integration of measurement hardware, sensors, and software to automatically recognize and configure available measurement components. This capability lets engineers build applications in fewer steps and with less programming, thereby decreasing development time. For instance, engineers can direct a remote computer to acquire data. Then, they can instruct a powerful workstation to analyze the results and publish the data anywhere.The measurement intelligence feature includes a comprehensive waveform data format that defines names, unit information, and frequency characteristics of measured signals. Users can employ it to integrate measurement data and hardware connectivity throughout many acquisition, analysis, and visualization functions. Single-icon measurement functions generate and manipulate waveforms. They also log waveforms to spreadsheet files and process measured signals. Compared to previous versions of the environment, LabVIEW 6i has improved execution, performance, memory usage, program load times, and file footprint size. Earlier editions computed a 10,000-point FFT in 693 ms, but 6i executes it in 25 ms. Many applications using 6i show a 20% decrease in application size and memory usage. Single-point data-acquisition rates are 4.7 times faster, too. Advanced computer graphics technology lets the environment deliver 3D user-interface controls for developing professional, easy-to-use measurement systems. Significant new graphic functions include multiaxis charts and graphs, along with a new digital I/O graph that represents timing data and digital patterns. Additional Windows-style controls include property pages, a multicolumn list box, and tip strips to describe user-interface objects. And, LabVIEW 6i boasts image-acquisition and motion-control libraries.LabVIEW 6i is available for Windows 2000/NT/9X, Mac OS, Linux, Solaris, and HP-UX. French, German, and Japanese versions also are available. Pricing starts at $995. Upgrade pricing starts at $395. National Instruments, 11500 N.

Accessing LabVIEW 6i Numbers from LabWindows/CVIThere are several different combinations for passing numbers in a LabVIEW function. LabWindows/CVI can access these methods similarly. The following Function Prototype has three numeric inputs and three numeric outputs. In/Out 1 are 32-bit integers, In/Out 2 are double-precision floating point numbers, and In/Out 3 are unsigned 8-bit integers. In1 and In3 are set up to be passed by value, while In2 is set up to be passed as a pointer to value. The three outputs must be passed as pointers to values.Note: You can use either Standard or C Calling Conventions if you are calling the DLLs that use numbers from LabWindows/CVI.To call the Numtest function, simply add the header (.h) file and library (.lib) file to your project. Also include the header file in your source code (#include ).The variables can be created in the code in the following manner:uInt8 in3 = 5;float64 in2 =3.68 ;int32 in1 = -100;uInt8 out3;float64 out2;int32 out1;The actual call to the function looks like this:Numtest(in3,&in2,in1,&out3,&out2,&out1);Notice that In2 and the three outputs need to take the address of their values since they were defined as being passed as pointers to values when the DLL was created. Accessing LabVIEW 6i Booleans from LabWindows/CVIWhen creating DLLs in LabVIEW 6i, you can only pass Boolean parameters as pointers to values. The following Function Prototype has one Boolean input and one Boolean output.Note: You can use either Standard or C Calling Conventions if you are calling the DLLs that use Booleans from LabWindows/CVI.To call the Booltest function, simply add the header (.h) file and library (.lib) file to your project. Also include the header file in your source code (#include ).The Boolean variables need to be created in the code in the following manner:LVBoolean in;LVBoolean out;The actual call to the function looks like this:Booltest(&out,∈);Notice the Boolean variables need to take the address of their values since they were defined as being passed as pointers to values when the DLL was created. Accessing LabVIEW 6i Arrays from LabWindows/CVIArray Data PointerWhen you pass an array as an Array Data Pointer, you must also pass a

To your project. Also include the header file in your source code (#include stringtest.h>).The variables can be created in the code in the following manner:char inputstring[5] = "hello";char outputstring[3];long inputlength = 3;long outputlength;The actual call to the function looks like this:Stringtest(inputstring, outputstring, inputlength, &outputlength);If this function simply output the same string that was input, it returns "hel" since the Input Length is 3. The value returned to the outputlength variable also is 3, because that is the number of characters that were output into the outputstring variable. Notice that outputstring is dereferenced since it is passed as a pointer to a value. Accessing LabVIEW 6i Clusters from LabWindows/CVIWhen creating DLLs in LabVIEW 6i, you can pass clusters of different types of variables easily as long as the elements are not strings or arrays. It becomes more complicated when strings and arrays are involved, so we recommend not using them. The function prototype below has one cluster input and one cluster output. The types of variables contained in the cluster depend on the types of controls and indicators that are contained in the cluster within the VI. The clusters are passed as pointers to structures.Note: You can use either Standard or C Calling Conventions if you are going to be calling the DLLs that use Clusters from LabWindows/CVI.LabVIEW 6i automatically creates a header (.h) file and library (.lib) file which you include in your LabWindows/CVI project. For clusters, the header file contains a type definition of a structure which contains the variables that are associated with the cluster. For instance, if the input cluster above contained a numeric control and a Boolean control then the following code is automatically generated in the header file (InNum is the name of the numeric control and InBool is the name of the Boolean control):typedef struct {float64 InNum;LVBoolean InBool;} TD1;The output cluster works in the same manner and the following code is generated:typedef struct {float64 OutNum;LVBoolean OutBool;} TD2;Note: The structure variables TD1 and TD2 correspond to the types passed in the Function Prototype above in the panel (void ClusterTest(TD1 *InCluster, TD2 *OutCluster)).Within the source file

Length Input which tells LabWindows how many elements are in the array. When you set up the parameter as an Array Data Pointer within the Define VI Prototype panel in LabVIEW, a Length Input parameter is automatically added to the function whether it is an input or output array. For an output array, you also have the option of using a Length Output parameter, which returns an integer that indicates the number of elements that were returned from the function into the associated output array. The Function Prototype for a VI that has an input array and output array with identical input lengths looks like the following:Note: You can use either Standard or C Calling Conventions if you are using LabWindows/CVI.To call the Arraytest function, simply add the header (.h) file and library (.lib) file to your project. Also include the header file in your source code (#include ).The variables can be created in the code in the following manner:double arrayinput[10];double arrayoutput[10];The actual call to the function looks like this:Arraytest(arrayinput, arrayoutput, 10);Accessing LabVIEW 6i Strings from LabWindows/CVIC String PointerWhen using LabWindows/CVI, we recommend using C String Pointers. For output strings, you also must pass a Length Input and Length Output. The Length Input tells LabWindows/CVI how many characters of the input string that you want to pass to the function. When you set up the parameter as an C String Pointer within the Define VI Prototype panel in LabVIEW, a Length Input parameter is automatically added to the function even if it is an output array. For an output array, you also have the option of using a Length Output parameter, which returns a pointer to an integer that indicates the number of characters that were returned from the function into the associated output array. The Function Prototype for a VI that has an input array and output array looks like the following:Note: You can use either Standard or C Calling Conventions if you are going to be calling the DLLs that use arrays from LabWindows/CVI.To call the Stringtest function, simply add the header (.h) file and library (.lib) file
