Description |

object |
An object expression that evaluates to an object in the Applies To list. |
Remarks
When using an expression such as AI1 > 55.0, the value of this expression is 0 when AI1 is less than or equal to 55.0. When AI1 exceeds 55.0 the value of the expression is 1. The OnTrue event is triggered when the value of the expression changes from 0 to 1. If the expression is a single tag, then the value of the tag is evaluated as either 0.0 or non-zero to determine whether to fire the event.
See the complete event firing event transition described in the DataChange event.
