subVI error

[eymen]

I try to measure the vibration of the cutting tool in CNC turning machine but when I try to run my program in the labview an error occur. The error is: ( The subVI is not executable. You must fix all errors in the subVI before this VI can run.). How can I fix it?

Thank you

Without seeing the VI (attach the actual VI, not a picture of it), we cannot tell you how to fix it.  If you have many VIs, and especially if you have them all as part of a LabVIEW Project file (.lvproj), you should compress the folder that contains all of them and attach the resulting .zip file.  Also, please tell us the name of the sub-VI that is generating the error.

"DAQ assistant" is typically an express VI that is part of DAQmx so it looks like something is corrupt. We probably need a bit of backstory.

• Who wrote the program?
• Are you running this in the development environment or as a standalone executable?
• Was it ever working before?
• What changed since the last time it worked (new LabVIEW or driver version, new computer, new configuration, new CNC machine, windows update, etc.)
