Query regarding event structure

[archit0392]

I have created a program as follows.

For the 2nd event I just need to replace the data in the array which is attached to VISA write.

My question is do I need to create a event again and again or is there another way out.

I am new to LABView.

Please Help.

What is your second event?

What do you mean by "create an event again and again"?

[archit0392]

I mean that for the second case which i need to create I just need to change the data in Array attached to VISA write.

And i need to make mutiple cases like this.How do i do it.

You can create an event for each new front panel control you add. No different than the way you created the event for the button you have now.

P.S. Your array should be changed to a U8.

Actually for the new control that i want to add, I need just the same structure on block diagram as for the previous case with the change only in data in array.

So is there a way ( like copy+ paste in word) to make this possible because i have to make 3 cases like this.

Thanks

If all of your event cases will be the same except for the array constant, turn all of that inside a subVI and put it outside of your event structure.  The idea here is that the event structure just passes out the data to send.

Is it possible in event structure to execute multiple cases sequentially from a single control on front panel..?

Sure.  Create a Queued State Machine.  Have your "Next" button send the "Next" State to the State machine, which you've programmed to generate the "Next" State (whatever that means).  So if you have Step 1, Step 2, Step 3, Step 1, Step 2, ..., set up your State Machine with these states + Next.  You need a Shift Register to hold Step 1, 2, or 3, then Next simply increments the Shift Register circularly and then queues up the resulting new State.  [It's much easier to "draw a picture" = write the VI than to say in words, but you'll want to have the fun of doing it yourself ...]

You can right click on the event structure and click "Duplicate Event Case...". This will duplicate any controls you have inside the event as well, but you can rename those if you'd like.
