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 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 diagra
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. When you perform any kind of input and output (I/O), consider the possibility that errors might occur. Almost all I/O functions return error information. Include error checking in VIs, especially for I/O operations (file, serial, instrumentation, data acquisition, and communication), and provide a mechanism to handle https://www.ni.com/getting-started/labview-basics/handling-errors errors appropriately. 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 http://zone.ni.com/reference/en-XX/help/371361K-01/lvconcepts/error_checking_and_error_handling/ 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 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 & 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 nu

Δημοσιεύτηκε στις 7 Μαρ 2013In this episode, we see how to conditionally execute code based on an error. We do it in a single VI, but then also make a subVI of the new code and create an error handler. We see how native LabVIEW VIs and f
