How to stop my program after a runtime of 30 seconds? My stop event is in an event structure.
Gerd seems to be better at reading between the lines, but it is really impossible to tell what you are actually doing, so start with attaching your VI so we can offer suggestions. There are many red flags in your description.
- Run continuously is a debugging tool, not a way to run a VI. (It can e.g. be used for quick standalone testing of a subVI that does not have a toplevel loop)
- An event structure cannot test devices. It is a structure. You did not even describe what triggers the event.
- What exactly is the program state after 30 seconds?
- You cannot "physically" press a virtual button.
- What is your program architecture (if any!). Where is the event structure? What are the event cases? What else is there? What is inside or outside the cases? (e.g. a test that takes 30 seconds should never be inside an event case)
- What is a cycle? (repeat same? new device? New settings?)
- What determines the 30 second runtime (timer polling? natural duration for the test to complete?)
One way to implement what you are trying to do, is to use a function to get time . Use it 2 times one BEFORE the start of the loop and one inside the loop, and measure the difference of both times, when the diffference is bigger than 30 seconds, then the loop stops.
As it has been shared, don't use continuous buttons, preferably learn the basics of state machine and implement it on the code.
