How Can I define rigid plane? I want to pour cubes which are in the image. However when I animate blender p plane passing through to the cubes. How can I solve this problem? I just want to pour cubes and observe falling of cubes when I animate.Can you Help me? 
Thank you...
[Final Edit now I think I understand the problem better]

OK, so I have the same behavior as you if I use your AN setup. Blender expects the passive to not be moving, or you to be explicit about it if it's moving.

So my solution:

Select cube, go to physics, add rigid body, select type active.
Select plane, go to physics, add rigid body, select type passive. Under settings, tick Animated.
Play animation.

It should work.
