Configure a truth table animation to use element styles

You can configure an element or a group of elements with a Truth Table animation that can select multiple Element Styles based on a set of evaluated values or expressions.

Truth Table animation is typically used to set Element Styles for the different states of an object. For example, you can set Truth Table conditions to show different Element Styles that represent the following alarm conditions:

• When the attribute TankLevel_001.PV is 0 then no Element Style is applied.

• When the attribute TankLevel_001.PV is less than 20, then the Element Style is Alarm_Minor_Dev.

• When the attribute TankLevel_001.PV is greater than the attribute Standards.TankMax then the Element Style is Alarm_Major_Dev.
