1. A system including an object entity within an object oriented programming environment for programming functionality including controlling a field device within a process plant and a display of the process plant, the system comprising:

  • a non-transitory computer readable memory; and

    a connection object stored on the non-transitory computer readable memory and executable on a processor, the connection object representing a physical connection entity of a plurality of connection entities that connects process entities within the process plant and including;

    a data portion that includes (i) connection parameter data related to a connection by the physical connection entity between process entities and (ii) one or more data inputs or outputs that communicate with other objects representing process entities connected to the physical connection entity to receive a representation of a stream of material from an upstream process entity and to provide a modified representation of the stream of material to a downstream process entity, the connection parameter data indicative of a connection type, a connection status, a type of flow through the physical connection entity, or a nature of the flow through the physical connection entity;

    a graphic representation for use in a control display, the graphic representation pictorially depicting the physical connection entity; and

    a method portion that includes one or more methods, which when executed on the processor, perform functions that represent material flow through the physical connection entity using at least one of the connection parameter data and the one or more data inputs or outputs for the physical connection entity corresponding to the connection object;

    wherein an instance of the connection object is included within the control display, the control display is communicatively coupled to a control module, the control module controls the field device associated with the physical connection entity.
