in the Section Automatic Error Handling Manual Error Handling Error Clusters Explain Error Using While Loops for 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. Automatic Error Handling labview error handling tutorial Back to top Each error has a numeric code and a corresponding error message. 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. 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. Manual Error Handling Back to top You can choose other error handling methods. For example, if an I/O VI on the block diagram times out, you might not want the entire application to stop and display an error dialog box. You also might want the VI to retry for a certain period of time. In LabVIEW, you can make these error handling decisions on the block diagram of the VI. Use the LabVIEW error handling VIs and functions on the Dialog & Us
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 error handler labview properly. Error checking tells you why and where errors occur. When you perform any labview simple error handler kind of input and output (I/O), consider the possibility that errors might occur. Almost all I/O functions return error information. labview visa error -1073807339 Include error checking in VIs, especially for I/O operations (file, serial, instrumentation, data acquisition, and communication), and provide a mechanism to handle errors appropriately.

You also might want the VI to retry for a certain period of time. In LabVIEW, you can make these error handling decisions on the block diagram of the VI. Use the LabVIEW error handling VIs and functions on the Dialog & User Interface palette and the error in and error out parameters of most VIs and functions to manage errors. For example, if LabVIEW encounters an error, you can display the error message in different kinds of dialog boxes. Use error handling in conjunction with the debugging tools to find and manage errors. 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 inputs and outputs. Error clusters typically provide the same standard error in and standard error

Sometimes we see beginning developers not using the error cluster because they just have no idea how it works. Let's take a look at what's in the cluster, the difference between manual and automatic error handling, and the behavior of standard LabVIEW VIs and functions when labview error handling they see an incoming error. This sets us up for a good discussion on error handling.For full video transcript, visit: http://blog.sixclear.com/post/4430929...For more on programming in LabVIEW, check out the Sixclear Lucid LabVIEW Fundamentals Training (previously Sixclear LabVIEW Fundamentals) course at http://sixclear.com/labviewtraining.You can also keep up with us at:http://facebook.com/sixclearhttp://twitter.com/#!/sixclearhttp://gplus.to/SixclearExperience level: Basic Category Education License Standard YouTube License Show more Show less Loading...

It's annoying when doing initial testing. However, very occasionally it finds an error cluster which I forgot to wire, sometimes in the middle of a crowded diagram, and that makes it worth it.

I second that. The main reason for this is that I like to manage error dialogs my self. /J Share this post Link to post Share on other sites LAVA 1.0 Content 1
