Value passed to the Task/Channels In control is invalid

May I assume I am getting this error because my application is looking for non-existent clone names when it runs? Any workarounds for this problem? I'm using 8.6 and Windows XP Pro.

Hi PaulG.,


You are probably referencing a task that does not exist, or has errors. There is a KnowledgeBase article on common DAQmx error codes that may help, as well as an article on error -200428 with DAQmx Base more specifically.
