Each column (B.01, B.10, B.60) represents the amount that a particular component was working during the past minute (B.01), past 10 minutes (B.10) or past 60 minutes (B.60).
For example, if the B.60 column shows 100 for V11#WP001 this means that it was working the entire last 60 minutes. It does not mean that it has reached the performance limitation. It is simply a notification that the WP was running.
These numbers are meant to provide information about how active the AE system has been. It is not meant to indicate the Automation Engines system performance either long-term or short-term.
