Why Do I Get a 10409 Error (Specified Group in Use) Error When Using NI 6533 and 6534Hardware: Digital I/O (DIO)>>High-Speed
Problem: I didn't get an error the first time I ran my VI. However, when I run my VI again, the DIO Config VI gives a 10409 error (specified group in use) and occurs every time I run the VI after that. Why is this happening? Solution: When an error occurs in a program that uses error cluster handling, the VIs following that error are not executed. One of the important VIs needed for DIO port writes and reads is the DIO Clear VI, which is used to clear the device of its current configuration. If this VI does not execute, you will get a 10409 error whenever you try to access a port that has been previously configured. The solution is to place a Reset Device VI before the DIO Config VI. NOTE: Make sure the reset occurs before the configuration. A flat sequence structure, containing the reset and passing out the device number, is a good way to guarantee that this will happen.
