Abstract

Management systems, methods, and mediums are provided. A method includes monitoring a value of a data point associated with a device in an automation system using a set of pairs of event enrollment objects and notification class objects configured to generate and communicate an alarm according to a first protocol. Each of the pairs of objects corresponds to one of a set of offsets defined according to a second protocol. The method also includes writing property values of the pairs of objects for different alarm monitoring modes using a set of command objects. Additionally, the method includes generating and communicating, in response to detecting the value for the data point meeting conditions in at least one of the event enrollment objects, an alarm according to a notification class object paired with the at least one event enrollment object.
