Re-Initialize after rerun the VI

[neiviv]

Hi Mike,

Sorry for lag of information again. What i mean is once i change the value from 5 to other value, lets say 8 and i stop the VI. When i rerun the VI, the value now stick to 8 and not 5. What i wish is that i hope the value will always be 5 even after i change the value.

Thanks for ur attention and sry for my mistake.

Hi neiviv,

ok, i think i understand you correct. I think thats exactly what happens in my last attached example. If you start the vi, both shift registers will set to 0 and this value will add to the control value. and now it is 5 again.

If you want to set the control value at startup everytime to 5, create a property of this control and set the value to 5 (see the attached example)

Hope this helps.

Hi Mike,

Its exactly wat i wan. Thanks for ur help.

Mind to help me for another problem? Is it possible for Labview to run a VI first(Same as the re-initialize all the value but it is use to initialize the hardware through controller) everytime we re-run a main VI without pressing any button or watever control.

For example, my VI containing 2 control values X and Y which represent the coordinate of my robot arm, after we rerun the robot(value changed b4), the vaue will return to the default value but my robot still at the previous location. Is it posible to return the robot to tat coordinate again without pressing any button(I have created a VI to return the robot to homing position, which is the default position, now i only need to run tat VI first everytime i rerun the main VI).

Thanks to you to Shoar.

Hi neiviv,

as i wrote before, you can use a state mashine. Use the example finder. Which communication way are you using to communicate with your robot (serial)? If you use a state mashine you can define one case for initialization (control, FP, Robot arm, ...) and another one your the main program.

State machine, i am not quite familiar with it using labview but i will try to test it out. I am using a USB port right now.

Thanks.

Here is how to do the VI reset programatically.

This will reset the VI to all the default values.
