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.

Description

Technical field [0001] Generally speaking, the present invention relates to the field of networked computerized industrial control and automation systems. More precisely, the present invention relates to a human-machine interface (HMI) used in association with industrial control and automation systems to facilitate observation of the status and operation of physical equipment and related information at the supervisory level. The HMI is usually connected to a lower-level control unit, such as a programmable logic controller or a distributed control system (DCS). Such a system is also used to collect and manage historical information related to such processes and their associated outputs. Background technique [0002] Industry is increasingly relying on highly automated data acquisition and control systems to ensure that industrial processes operate efficiently and reliably, while reducing their overall production costs. Data collection begins when many sensors measure several cond...
