Refer to the KnowledgeBase for more information about correcting errors in LabVIEW. 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 occurre and displaying an error dialog box.

To disable automatic error handling for the current VI, select . I do not want to contact National Instruments Support every time I receive these errors , so where can I find descriptions of the error codes?

This document contains tables listing all the numeric error codes for LabVIEW. You can get this error both in the LabVIEW Development Environment as well as from a built executable. It indicates that LabVIEW could not take control of the Serial Port. The following are the possible causes as well as the solutions to these errors : Another program has control over the serial port. The static method is supposed to give me an instance of the object.

I have tried: – assembly is in the same directory as the calling vi. If the VIs do not return a description, the error code text files might have been move delete or corrupted.

This problem usually occurs when you use user- defined error codes, applications or shared libraries, or drivers released before LabVIEW 6. You often can solve the problem by taking the following actions. Write To Spreadsheet File (DBL). Possible reason(s): LabVIEW : Unexpected file type. I am outputting a sequence of characters from a third party device at a fixed interval and reading it using a VISA Read VI. This module teaches you how to identify and troubleshoot both types of errors.

If LabVIEW cannot run your VI, it informs you by changing the run arrow to a broken icon, and the Error List window lists the specific reasons why the VI is broken. The second type of bug is typically harder to track down, but LabVIEW has several . This book includes tables of numeric error codes and the descriptions for these errors. VIs and functions in LabVIEW can return numeric error codes.

The error code tables are arranged in ascending order, from. This example converts a single error to a string or an array of errors while only writing errors that have occurred. I have some fairly complex code that I have written that does Bit Error Rate testing using multiple launches of asyncronous writers and readers, and. Users can encounter errors in even the most reliable VIs.

Without a mechanism to check for errors , you can only know that a VI does not work properly. Error checking identifies why and where errors occur in your VI.

For example, one common situation in which you can encounter errors occurs when you perform any kind of . Requires: Base Development System. Converts an error or warning code to an error cluster. This VI is useful when you receive a return value from a shared library call or when you return user-defined error codes. Use the Error Ring to quickly select and pass NI or custom error codes throughout your VI.

You can configure the ring to return a built-in error message or you can create a custom error message for a one-time use.
