how to transfer a data gernerated from a VI to Simulink?

[jinxj]

Hi,

I am now using Labview and Simulink together to control Agilent 34980. Labview is th interface between Simulink and Agilent 34980.

I am now successfully to control 34980 from Simulink but when I want to transfer data get from 34980 to Simulink, a problem shows up.

Now let me simple the question.How to transfer a mid-data to Simulink? You may see the eg. below.

I want to tansfer Number and Number 3 which is the result of "Number + Number2" to Simulink. And they will be added in Simulink, the result will be transferred back to number 5.

Cause SIT only can transfer Control VI to Simulink ,so I use "local variable,局部变量".

But when the Labview run and when I change Number and Number2 in the front panel the Number3 changes soon, but the Number5 does not change,it seems I didn't transfer  Number3 to Simulink soon,Why?

I appreciate any reply, Thank you a lot~

Hi, Srikrishna!

Thank you very much for your reply.

But it seems that it can not solve my problem~

My question is how to pass a data generated in labview(not Contol) to a simulink model?

Do you have any good suggestion?

Thanks a lot~

I am having the exact same problem, I can transfer a Control to Sinulink, but i cannot pass a labview indicator (i.e. a result) to simulink. I have tried all sorts, including wiring the result to a property node box that sets the value of the control. The SIT toolbox seems to opperate at a higher level than the labview VI. This is evident becauce the controls that are been passed to simulink in the sine wave.vi example are not inside any sort of loop, yet the program will continuasly read from them as if they are!!! Any solutions please?

Hi Welsh Jack,

  I think you can work around this problem using property variables,frame structure and another hidden control.As shown in the above post,there are two variables x and y and sum is Z,now create a local variable or property value and wire to hidden control's local variable in one frame ..This way you can work around that problem..

Thanks and regards,
