FieldPoint devices and LabVIEW program for educational project

[stn]

I use LabVIEW 7.1 and NI FieldPoint devices (FP-1000) for educational
purposes. I want to control a automation unit which has got 6 digital
input(DI) and 5 digital output(DO). I used the sequence structure, but
actually I am not sure the solution whether true or not.

Working principle of my system:

If "Channel 1" DI is ON, DO Channel 10 must be "ON"(turn table motor
Start)

If Channel 2 DI is ON, DO Channel 10 must be "OFF"(turn table motor
Stop) and DO Channel 11 must be "ON" (drill motor Start) and after a
delay time DO Channel 12 will ON (drill motor down)

If Channel 3 DI is ON, DO Channel 12 will OFF, a bit of delay time DO
Channel 13 ON ( drill motor up)

If Channel 4 DI is ON, DO Channel 13 and Channel 11 will be OFF (drill
motor stop) and then DO Channel 10 must be activated.(turn table again
Start)

If Channel 2 is ON again DO Channel 10 will OFF and check cyclindir
control Channel 14 will ON, after a delay Channel 14 will OFF

If Channel 5 DI is ON, DO Channel 10 will ON again while DI Channel 2
is ON.

How can I project the system with LabVIEW 7.1?

Thanks, stn

Your description is not particularly clear.

For example, what happens if DI 1 and 2 are True at the same time? Is DO 10 T or F?
What's the difference between the DI 2 at the beginning and at the end?
And so on...

As a start, I suggest you try searching this site and google for LabVIEW tutorials. Here, here, here and here are a few you can start with and here are some tutorial videos. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

To get more details about might be relevant for this case, try searching for "state machine" and look at the examples in the File>>New dialog.

Other than using the state machine template in LabVIEW, be sure to have a look at the NI LabVIEW State Diagram Toolkit.

This is a pneumatic technical experiment set. Your suggestions okey
but I have already studied these subjects.I have tested a solution for
the system using the sequence structues in the LabVIEW. But if you
sent to me an example vi, I will understand the solution way.Thanks.

Working principle of my system as a summary:


Step 1: When DI 1 is ON, DO 1 must be "ON"(turn table motor
Start) while DI 2 is ON. In this case DO 2 must be "ON" (drill motor
Start) and after a bit
time delay DO 3 will ON (drill motor down),

Step 2 : when DI 3 is ON,(drill bottom level), DO 3 will OFF, after
that DO 4 will ON ( drill motor upper position) in this case DI 4 is
ON, after that DO 1 again ON while DI 2 is ON (like step 1)

I really still don't understand what you're trying to do, but here's some example code. Maybe it will help you. This is not how my code would look, but I have no idea what your code is supposed to do, so I can't give any real advice.
