Custom Error Codes Labview
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. Poor|Excellent Yes No Document Quality? 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. If you have several error wires and you want to retain the information from all of them your only built-in option is to build an array of error clusters to transport http://swirlvision.com/custom-error/custom-error-labview.html

To relieve you of the need to explicitly convert things to variant type, I incorporate a red dot in VI icons at variant terminals.

Anything can be automatically converted to a variant, so wiring either an enum or an I32 to Chained Find First Error will result in a coercion dot. weblink LV looks up in this database when handling error lookup. 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.
