I was wondering if there is any method to use single camera multiple times in the same VBAI program with different exposure settings?
I am working on one application where it is require to use different exposure times with same program.
Thanks and Regrads,

If you're using a GigE, USB camera, use the Read/Write Camera Attributes step to change the exposure time. If you're using a NI Smart Camera, the last tab of attributes allows you to select the exposure time and associate it with a previous measurement, or you can have multiple acquisition steps that use different exposure times.
Hope this helps,
In addition to what Brad's answer, I will say you should be careful about how you set up the acquisition : for instance, if your acquisition step mode is set to "immediate" or "every buffer", you may sometimes get an image that has been acquired prior to the exposure time change.
Also, the exposure time change in the camera may not occur "immediately", depending on the camera for example, it may be applied 1 image after the camera receives the command.
