Activate switch issue

[Gagan21J]

Hello,

I'm using Matrix module in my test setup.

Trying to switch signal_x to 24V using Matrix card c1->r0 and then after certain delay of 1 sec, would like to enable signal_y to 24V (c2->r0). when I perform second signal enabling both signal_x and signal_y should be at 24V.

But I'm facing a issue that the signal_x will be disconnected when I try to switch signal_y.

Can some one help, how can I program them so that both signal will be enabled with a delay as explained above.

c1=signal_x

c2=signal_y

c3=signal_z

r0=24V

You need to post some code.

What you explained might make sense to you, but not to us. At least not enough to know what is wrong or what you try to do.

What is "Matrix module"?  Is this a piece of hardware (and if so, what, specifically)?  Is this the mathematical 2D array of numbers we fondly remember from Linear Algebra?  Are these the "matrix" functions (related to the previous question) found in LabVIEW?  What do voltages have to do with anything?  What are you trying to do?  Where is your VI (no pictures, please) with which you need help?

In our application we are using NI module to test the hardware functionality of the Board.

We are using two switch modules in two sub VI's where the following three functions are performed namely 1) switch initialization 2) Switch connect and 3) switch close .

The working procedure is divided in two stages where  in stage 1 ( in 1st sub VI),The two columns c1 and c2 ( Switches ) are shorted and connected to row r0 where r0 is connected to 24 V supply. As r0 connected to c1 and c2, these switches goes to 24 V and after 100 ms time dealy that is in stage 2 the same r0 is connected to c3, now c3 goes to 24 V that is high but at this stage c1 and c2 is going to 0V which should not happen and it should be in 24 V itself as we are not disconnecting c1 and c2 these are connected in matrix form.

Find the attached Block diagram for reference.

 Can any one help me why these switches c1 and c2 is going to 0V at stage 2 even though we are not disconnecting .

Thanks in advance.

Hi Neen,

why don't you team up with your team member before creating duplicate threads for the very same topic?

As has been said before: please name the hardware and which driver you are using!

And post some code.

You're just telling us what you want and that it doesn't work. How should we know why it isn't working?
