Multi Channel Data Acquisition using PXI-6143

Hi all

I can acquire one channel data and am trying multi channel data acquisition using PXI-6143.

And I made attached code.

But in this code, the signal in ch1 is acquired and in ch2 is not acquired. Why?

FrontPanel.pdf is the front panel of this code during operating.

AI1 and AI2 are input same signal 1Hz sine function.

I'm grad if you teach me the solution.
