Events Model
Events are a fundamental part of production. The events model is used to map out the critical events that occur to control production. These events can be created within this application or from external systems, and can be used to control workflow execution.
Condition Events
Condition events are defined by logical expressions against variable values. When these components are set and enabled, they are monitored by the system. When expressions evaluate to true, the event occurs and subscribers to the event are notified.
Evaluation of Condition Expressions
The Trigger Settings tab allows you to determine when the configured condition expressions will be evaluated. The results of these evaluations determine whether or not the event can run.

      - Properties and Attributes of Condition Events
        The Details tab offers general information about the selected condition event.
      - Evaluation of Condition Expressions
        The Trigger Settings tab allows you to determine when the configured condition expressions will be evaluated. The results of these evaluations determine whether or not the event can run.
        Set a trigger for a conditional event
        Set up class-based events
        You can bind class properties to event variables so that an event can detect a property change in any equipment to which that class has been added.
        Create variables for a condition event
        Create an expression for a condition event
        Condition Event Expression Variables
        The Variables tab allows you to add, modify, and delete expression variables to use when building event expressions. You can define one or more variables, which can be a constant value bound to an attribute of the trigger event, or bound to external data.
        Condition Expressions
        The Condition Expressions tab allows you to create expressions using mathematical or Boolean logic.
        Event Sources
        Event sources are data items that you can subscribe to.
