RobotStudio event

configuration of IRBP B Manipulator

What is the correct way to confige an IRBP B manipulator?

If I build a system in robotstudio, with a irb 2600 and a irbp B manipulator, place a workobject on each plate, at 0,0,0, then the robot is only able to reach the workobject connected to the first plate.
When the interchange has turn 180 and I try to make the same movement on the second plate, the robot cannot reach. 
I found out, that the reason for this is that the 2 plates is not moved by the interchange, in the robot, so It thinks, that the plates are not moved.

a workaround would be to configure the 2 plates, to be placed in the same position, instead of where the actually are, when the interchange is at 0.
But is that the way to do it, or is there a more correct way, where the interchange is included in the position of the plates?
