How to take Control Action

[Government]

Hi

I have already developed an application using Measurement studion component works CWAI Activex under Visual Baisc with three VXI-MIO-64E1 modules. We are acquiring data from VXIDAQ modules contineuousely and writing in binary data file in hard disk.

Now I want to set alaram on all my analog input channels. When input voltage crosses preset value then digital output has to be generated. In parallel i don't want to disturb my contineouse data acquisition.

If i wait till CWAI ActiveX fire Acquisition events and compare for each data point in buffer with alarm, it takes time.

Is there any best way to implement my application ???.

regards

Gaurav

Hello;

Since that board of yours only supports unstrobred digital operations, meaning that you need a Software call to update the digital line; the only way to update the digital line on that board, is by doing what you are doing now.
