Robot Statistical States

Hi, I am working on a machine tending cell using two differente resources: A human and a Robot. I am using “Anna” and the VC Generic Robot. I want to obtain a statistic graphic of the states of the robot (No problem for Anna), but for the robot seems to be always 100%. I do not if I need to create these states first or how can I get the states from the statistics. When I say states I mean Idle, busy, or utilized.

Thanks.

Note: I am using version 4.1
