The following table is an example of how to configure an Event Enrollment Object using the Floating Limit event type. In this example, the Event Enrollment object references the Present Value of an Analog Input Object. An alarm message is generated as defined by its Event Enable attribute when the value of the AI’s Present Value attribute exceeds the defined setpoint (ZNT-SP) plus the high or minus the low differential limit values for a time period longer than the defined Delay Time. For more information about this event type, see Event Type.
