Without a mechanism to check for errors, you know only that the VI does not work properly. We do it in a single VI, but then also make a subVI of the new code and create an error handler. In reality, these and other device specific files should more probably be in the appropriate device folder in the instr.lib folder. Rating is available when the video has been rented.

In most cases, a selection of well-named and well-described errors is probably the more convenient approach, however.)

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 These values should be brief but intelligible. (The Dipix names were longer than we would have liked, but we kept them as is to facilitate comparing LabVIEW and C code. Different projects use different equipment. http://softacoustik.com/labview-error/labview-error-cluster-to-string.php 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

In fact, if customized, detailed, individual comments were used religiously, only a single, generic error with no explanation at all would be perfectly suitable. If the first value is defined as zero, then why not use the string entry for that value to indicate an offset to apply to all other values to put them This is a perfect application for an enumerated type def., but we'd like an enumerated variable whose values are in the User Error Range and not simply a continuous positive progression http://softacoustik.com/labview-error/labview-error-cluster-for-loop.php 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.
The first time in any session that one of these error definition VIs is called, it parses the information into forms more useful to the computer (Figure 4). Sorry!) Conclusion Isn't this the way the error package should work? The text table is fine for the human interface, but the computer prefers different formats.
