Help - University project

[Isabela / Eduardo Scarabelli]

Dear all,

We have been preparing a university project using Labview software. We
need to prepare a labview program to set three pneumatic valves, that
this 3 valves will be responsable to set three pistons in a wooden
table. Could you please help me with this program?

We would like to send you an appendix with the diagram of this idea
but unfortunatly it is not possible to appendix a document here.
Because of this we will try to explain the situation below:

Imagine that these pistons are settled in a wooden table and each one
is responsable for one work.
1. One piston will be responsible for vertical movement (15
centimeters) during 60 seconds.
2. Other piston will be responsible for horizontal movement.
The wood board dimensions are: Lenght: 40 cm, Width: 20 cm, Thickness:
1,5 cm.
This piston movement will be each 7 cm, cosidering 60 seconds for each
work.
3. The third piston need is responsible to another work, he needs to
recieve a signal to make a movement of 15 centimeters.

We are looking for your help as soon as possible.
If possible, send us an email that we can send you a picture of the
system.

Thank you very much, kind regards,

Isabela / Eduardo

That sounds like a very interesting project, except you have not told us a single thing that could help you.

What is controlling the pistons?
I'm assuming each piston has a motor. How does the motor communicate with the computer?
GPIB, serial, USB, etc.

You can work with VISA tasks to create digital signals.

Could you please provide some more information.

And, it is certainly possible to attach files to a post. Simply use the 'Add Attachments' below the message body. Of course, there are restrictions on the types of files you are allowed to attach. For example, you are not allowed to attach a bmp file.

You also might want to add which version of labview you are using.

And, you should note down an email address somewhere as well if you want us to send you one.

Wouldn't it be better to ask your professor for some help?

Hi Isabela,

I have used  pneumatic valves with LabVIEW.

they are generally controlled by solenoids,

which could be activated by a simple DIO card itself.

Or even one could stick on parallel port with proper

interface maintaining the correct voltage-current

levels .

Sundar.
