(Windows Only) The following ranges of error codes are reserved for you to define custom error messages: -8999 through -8000 5000 through 9999 500,000 through 599,999 labview error handling best practices Complete the following steps to define custom error codes. Add the General Error

Handler VI to the block diagram. Right-click the [user-defined codes] input and select Create»Constant from the shortcut menu. An labview error handling tutorial array appears. Double-click the numeric constant and enter a number within the range of -8999 to -8000, 5000 to 9999, or 500,000 to 599,999 in the array. For example, enter 5008. automatic error handling labview Right-click the [user-defined descriptions] input and select Create»Constant from the shortcut menu. Another array appears. Double-click the string constant and enter a description in the user-defined description array. For example, enter Ignore this message. Right-click the error in input and select Create»Constant from the shortcut menu. A cluster appears that contains a Boolean constant, a numeric constant, and an array. Use the

Operating tool to set the Boolean control to TRUE. Double-click the numeric constant and enter the same number that appears in the [user-defined codes] constant. NoteAs an alternative to steps 6 through 8, you can wire a numeric constant with a value of 5008 to the Error Cluster From Error Code VI. Then wire the error out output of the Error Cluster From Error Code VI to the error in input of the General Error Handler VI. Run the VI. An error dialog appears and displays the customized error code and description. Click the Continue button in this error dialog. Double-click the General Error Handler subVI and view the front panel. Switch to the VI in which you defined your custom error code, and run the VI again. Notice that the message text box on the front panel of the General Error Handler VI displays the same customized error code and description as the error dialog. You also can define custom error codes by creating an XML-based text file and adding the error codes and messages to the text file. YourFeedback! Poor|Excellent Yes N

The LabVIEW built-in error codes ship with specific error code https://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/creating_user_defined_erro/ ranges. You can, however, define custom error codes using the following ranges: -8999 through -8000 5000 through 9999 500,000 through 599,999 You can define custom error codes in the following ways: To create multiple https://zone.ni.com/reference/en-XX/help/371361L-01/lvhowto/def_cust_errors/ error codes for use throughout your application and distribute them in built applications or shared libraries, use the Error Code Editor dialog box. To create custom error codes that do not need to be widely used in your application or distributed in built applications or shared libraries, use the General Error Handler VI. To create a single custom error code for one particular instance in your application, use the Error Ring. YourFeedback! Poor|Excellent Yes No Document Quality? Answered Your Question?

LabVIEW version: 2012 and newer.Installer: VIPM.Dependencies: None. Error & Warning 2014 toolset Setting, clearing, modifying, and inspecting errors and warnings in LabVIEW. Getting error information propagated through your application is probably one of the most universal tasks you encounter, and yet getting those error error handling messages formatted correctly is both quite complicated and takes up a lot of code space. Even though the error cluster and the error wire are some of the most widely recognized features of LabVIEW, they are quite frankly also all too often shrouded in misconception, inevitably leading to incorrectly formatted error messages or missed feature utilization. Set and clear errors and labview error handling warnings Set errors and warnings with the proper call chain. Optionally add custom reason descriptions and timestamp. Clear errors and warnings more efficiently than with the built-in functions. Filter errors Filter single or multiple error codes, or filter repeating or recurring errors without having to specify error code. Define global error descriptions at runtime LabVIEW lets you define custom error code descriptions statically by use of error code files, but there is no built-in functions to do it at runtime. This toolset provides a very easy way for defining custom error descriptions at runtime. You can append descriptions to existing error codes (useful if your application's error codes overlap the built-in set), and you can set error descriptions for user defined error codes.For error codes you define like this you don't have to supply any description at the error points in your code, unless you want to append an even more specific explanation. Using this feature each application can programmatically set all its own error code descriptions when it initializes for instance. Append errors LabVIEW has a built-in Merge Errors fu
