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.
