application control

[Dennis_Knutson]

I've only had to time to briefly look at your program. I'm a bit confused as to why you're using the rendevous. It would also appear that it's the subVI that's trying to dynamically open another VI. I can't figure out how the main VI is supposed to show the front panel of the channel VIs either? I had to delete some stuff in order to get your main to run at all and I manually opened the channel VIs in order to see what was going on. Id did notice that the rendevous was timing out and I'm not sure if that's the intended bahavior. I don't know how much time I'll be able to spend looking at it but if you could explain the idea behind the main and the rendevous, it would help.

Hi ,

I have been trying to develop a labview program which could run 4 channels of a loadbox simultaneously. Here i am trying to route all the input/output commands of all the subvi's( about 5 programs per channel ) through the control panel to the instrument so as to minimize the memory usage. COuld u help me on this.

bye

Could not run the application due to missing VIs. First of all, I doubt the subVI called using VI server were actually running. Yes, they were loaded and displayed in edit mode, however, this does not neccessarily mean they are running. As others suggested, a case or event structure is more appropriate.

In labview, goto menu >> Help >> find examples, search for "state" or "state machine" for some examples.
