I check with Task is Done successfully if a Task was already started for AI and DO tasks. However, an started AO task, without timing configuration returns immediately after start: task is done, despite the hardware is generating at that moment. A following start returns an error, since it is already running. Yes, what a beauty. Ok, how can I retrieve the running status without clearing errors?

AO Task is Done despite running generation

Thanks for your feedback. You are right, that this behaviour is not a show stopper at all and that there are ways around.

My point is, that it is reasonable to expect that one can query if one device is currently generating. NI backs this:

Using Is Task Done

You can use the Is Task Done function/VI for applications in which you need to monitor the progress of a task running in one section of your application from another section of your application.
