Why Do I Get a 10409 Error (Specified Group in Use) Error When Using 653X Hardware: Digital I/O (DIO)>>High-Speed
Problem: The first time I ran my VI I got an error. 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 most well written programs with error cluster handling, the subsequent VIs following the error are not executed. One of the important VIs needed for DIO port writes and reads is the DIO Clear.vi 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.
