Ramp up, Hold, Ramp Down

[LDA]

Very new to Labview, this is my first "task".

I need a specified voltage to ramp up with an input ramp time, then hold for an input time, then ramp down with the same time scheme as the ramp up.  I'm about half way there, or so I think. 

Any help would be appreciated, thanks in advance.

I added a very simple state machine to your program. I am sure that everyone will tell you that using the local variables is bad. There are better ways to handle that data but I did not want to spend all day giving you and example to work with. I added a Strict type def for your states. I added along with the new program.

I appreciate the response but I'm unable to open either attachments. 

I have an older version of Labview (8.5), is it possible to send again as an previous version?

Thanks

8.5 here you go

[LDA]

Again, I appreciate the support however this solution seems a bit complex for the level I'm at, at this time.  

Is there a simpler method or any tips I can play around with?

This is really a simple solution. What are you finding hard to understand? I would be happy to explain anything that you are not grasping.

Like I said I'm really new to the Labview, like I just cracked the book open last week new...  I made my way through many examples, however I think I've gone about as far as I can go at this point.  Thinkin I've bit off more than I can chew, maybe it's time to take a few more tutorials.

aestet, I'll take your help if you're still offering it, just trying to ramp down after the hold.  

Thanks

Here is an update of your code that works. Let me know if you do not understand something. It is about as simple as it gets.

Hmm... Doesn't seem to be working for me.

Sorry, I made one change before I sent it to you and it made a big difference I guess. : )
