Labview Error Cluster Warning
In LabVIEW, you can make these error handling decisions on the block diagram of the VI. Using While Loops for Error Handling Back to top You can wire an error cluster to the conditional terminal of a While Loop or to a For Loop with a conditional They are all compatible with the standard error-handling routines from National Instruments, so they integrate smoothly with your current code. niglobal 30,029 views 8:15 Errors Clusters and Handling for Lab View - Duration: 5:09. this contact form
To facilitate this, we have upgraded our workhorse Chained Find First Error.vi to accept the new error enums interchangeably with the old-fashioned error codes (by incorporating Variant to Error Code within Manual Error Handling Back to top You can choose other error handling methods.

If the error(s) come from subVIs or subsections of your VI, you can specify the origin(s) more precisely using the Subsources input to Chained Find First Error.
Those of you who have used them know that they use VIs nearly identical to those shown in Figure 1 and Figure 3 feeding the [user-defined codes] and [user-defined descriptions] inputs Add Comments 1 2 3 4 5 My Profile|Privacy|Legal|Contact NI© National Instruments Corporation.

You also know that they remember the type of dialog specified most recently, so that a dialog type could be set in one place and be effective for all instances of weblink Please try again later. Or you can fix the error programmatically and then erase the error by wiring the error-out output of the subVI or function to the error in input of the Clear Errors The new version of Chained Find First Error solves this problem.
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. Error Clusters Back to top Error handling in LabVIEW follows the dataflow model. Transcript The interactive transcript could not be loaded. navigate here Wouldnt it be nice if these enums could contain a few errors, e.g., file not found or timeout, with the error codes that NI assigns?
The shortcut menu includes an Explain Warning option if the VI contains warnings but no errors.
For example, if LabVIEW encounters an error, you can display the error message in a dialog box.

Examples for the two data sets presented in Figures 1 and 3 above are presented in Figure 8 below. As the VI runs, LabVIEW tests for errors at each execution node.
For example, if LabVIEW encounters an error, you can display the error message in different kinds of dialog boxes. Poor|Excellent Yes No Document Quality? Zero is LabVIEW's choice (and the choice of most other programming languages, as well) for the "no error" case. his comment is here Use error handling with the debugging tools to find and manage errors.
