Abstract: An industrial control and automation human machine interface (HMI) technology is disclosed that includes a centralized definition of data quality and status behaviors for graphical elements. The centralized definition is thereafter applied to every graphical element that is linked to a data value for which status is maintained/provided. Centrally configured data quality and status indication behaviors are incorporated across entire HMI applications and even sets of HMI applications in a system to inform an operator of the data quality and/or status of read/written data through globally defined data status animation behavior. The centrally defined behaviors are distributed to all nodes on a system and incorporated in live applications without shutting down the applications to update their behavior definition. A status graphic element type. The status graphical element examines a designated data variable and displays a picture or icon indicating the quality or status of the data.

Abstract: An industrial control and automation human machine interface (HMI) technology migration scheme is embodied in object management, graphics technologies, and namespace handlers for HMI applications. New features of the second technology are supported for HMI graphics while retaining the functionality of systems embodying the first technology, including the ability to export to the first technology, graphics developed and/or managed in the second technology. A combination of facilities is provided to accommodate both the first and second HMI graphics technologies: name space integration, graphics rendering integration, and HMI application management integration.

Abstract: The present invention provides central management of custom properties, including graphic facets, for an industrial control system. Standards for the custom properties are centrally developed and are then propagated to projects. Even after one or more projects have been developed, the custom property can be centrally changed, and the change can be propagated to all existing projects to override previous properties in the projects. With central management of the graphic, the inner functionality can be abstracted from the location where the graphic will be used. In some embodiments, a custom property is given a default value. That default value may be overridden in a particular project or at particular time, but the property can always revert back to the set default. Some custom properties may be “locked” to prevent user modification, and some properties may be set to be invisible to the end user.
