ReturnThe Unit Test Framework may remove trailing zeros from fixed point numbers in the reports it generates. Workaround:Change the numeric representation of the number, or append a small value to the number so the zeros are displayed.
If you have this pattern and attempt to build an executable you could receive error 1502 Workaround: Don't use unreachable code Reported Version: 8.6.1 Resolved Version: 2011 32-bit Added: 04/20/2011308464 Return LabVIEW cannot build some large applications because it fills the image table. ...
This page’s default configuration will use the test bench defined previously to propose fixed-point ranges based on the data used. Click Analyze to run analysis using the test bench. After the analysis completes, click Validate Types to confirm the proposed data types. Review the selected data...
During a code review, ask and answer some of the following questions: • What happens if a specific VI or function returns an error? Are errors dealt with and/or reported correctly? • Are there any race conditions? An example of a race condition is a block diagram that reads from ...
