Take multiple inputs from BNC2120

[hanut]

I have a BNC2120 board.

I need to take inputs from two channels and display the outputs on separate waveform graphs.

My current VI takes two inputs from channel A2 and A6 and the data is sent to waveform graph 1 and 2 thorugh a signal splitter.

I however see the same signal on both the graphs.

I am a beginner with LabView and need the solution asap!

Thanks

Don't yell at us, then 

Why don't you show us your code so we can see what you have tried?

[Dennis_Knutson]

The BNC-2120 is just a dumb terminal block so you won't get any signal at all from it. What is your actual DAQ device? As mentioned, also need your code.

Not shouting! 😄 

Secondly, i just have that one so can't do anything about that!

I am attaching the VI. Its a pretty basic one.Do check it out!

[PeterFoerster]

So, I just did do check it out and don't immediately see an error.

Here are a few remarks:

• You wrote AI2 and AI6 in your inital post, but the VI acquires from AI2 and AI4
• Where is the "signal splitter" you wrote about?
• Where are the separate Waveform graphs?

Sorry.. I accidentally uploaded the other VI i was working on. So here's the one i described to you earlier.
My board is PCIe-6323.

So what happens, when you connect another graph directly to the output of the express VI? Do you see two identical graphs,too?

What happens if you use index array to access the values?

What happens in either case, when you simply disconnect the cable?

(I'm not normally not one to bash the use of express VIs just because, but I just remembered what a nightmare the dynamic datatype is)

When i connect the graph directly, i see two graphs on my screen, with different colors (they can be defined in properties). The same problem however, they follow each other with a little gap on the Y- axis.
When i disconnect the cable, i see just the connected signal on my graph. and everything runs normally.

I haven't tried index array yet due to the simple reason that i don't know how to. 😄

If there is a possibility that it solves my problem, do you mind explaining to me or pointing to a source that can help me implement it.?

and yes i have seen dynamic datatype and as a beginner, i could'nt even start understanding what was going on there! 😄

I have plans to learn it in future but for now, i would like to stick express VIs! 😄
