Equipment KPIs
In Data Acquisition, a bar shown at the bottom of each primary equipment tile provides a visual indication of the key performance indicators (KPIs) configured for that type of equipment. When you hover the mouse over a button on the KPI bar, the details of the KPI are shown.

A red button on the KPI bar indicates the fact that the equipment unit is under-performing. In other words, the key performance indicator (Production Rate for example) has fallen short of target.
For any KPI on the KPI bar, you can click the mouse to select the KPI and display a graph which shows a history of KPIs for that equipment unit.
