HELP!!! I can't initialize my VI after stopping it!

[student1981]

Hi all,

really need some help here.. The problem is that firstly, when i stop the vi from running, and try to run it again, it doesn't initialize to the original values, instead, I have to make some kind of change to the block diagram( by changing some constant values for example), and den when i run it again, it is able to work fine. Any clues on how to fix this?

Of course it doesn't initialize after stopping. You have not written any code to do so. To do it manually, all you had to do was to select Edit>Initialize to Default Values. You also seem to have been running the program with the run continuous button . DO NOT USE THIS. You need a while loop around your case statement and then initializing it is simple.

See the attached modification. I also cleaned up some of the unnecessary code.

Your first problem is that it doesn't "run" at all.  You've written it in such a way as you need to "run continuously".  Put your block diagram into a While Loop (and add a Stop button) and you'll fix that and be on your way to fixing your other problem.  I'm not sure I understand what you mean about initializing to "the original values", but take a read into Shift Registers and see if that's what you're looking for.

Student-

Simple answer- you have an uninitialized shift register in your for loop.

Look into Functional Globals, shift registers, and action engines.  You will learn in time
