The FInal Step, i have created a program to all my specifications and i am now ready to connect the hardware

I have created a program to all my specifications and i am now ready to connect the hardware.
My program was created to automate the cleaning process of an atmostpheric chamber. It controls two valves based on the pressure readings and time intervals. When creating this program i figured that if a could make a boolean turn on or off based on the pressure readings then it would be no problem somehow wiring it to send a signal to the hardware. I have reached that point and don't know how to proceed.  I was told that the first step is to figure out what kind of Card is being interfaced with the program. 

I have read up on this subject and it seems like there is many ways to do it.

All sugestions will be greatly appreciated

First open the Measurement&Automation Explorer (MAX) to find out which cards are available. Create a Task for digital output in MAX using the card and the port and line. Then open the Example Finder in LabVIEW and find the examples for hardware digital output. Look at the exapmles to learn who to use the task you generated in MAX.

I'm not sure how you can create the program without knowing what hardware you're going to be using. But...  What have you read up on? You will need to select your data acquisition hardware. What kind of signals do you have? What kind of transducers do you have? What kind of actuators do you have? You may want to start with:

EDIT: Re-reading your post and seeing Waldemar's response: Do you actually already have a card installed?
