Benefits of technology

[0012] In accordance with the present invention, method is disclosed for creating, within a control program development graphical editor facility, a connection between an I/O attribute of a control object graphically represented on a first control strategy canvas and a second control strategy located outside the first control strategy. Such connections are supports by a declaration which acts as a connector between attributes otherwise embedded within two distinct control strategies.
[0013] In accordance with the present invention a method of designating and defining a declaration and its associated connected attributes is accomplished by initially specifying a name for the declaration within a declarat

Problems solved by technology

Automated control systems for typical industrial processes are often complex.
Developing customized control programs for such automated control systems is, of course, a complex and time-consuming task.
The template-based control development toolkit approach to developing automated control programs does not eliminate low-level programming altogether.

Embodiment Construction

[0033] A graphical user interface-based editor facility for defining control programs (e.g., control strategies described herein below) for processes is described herein below by reference to figures illustratively depicting an exemplary embodiment of the invention. In accordance with the illustrative embodiment, the editor facility provides graphical user interface-driven functionality including, among other things: supporting a set of appearance objects defining a variety of depictions for a single control object (e.g. a control block object, a control strategy object, etc.), connecting input and output attributes of control objects through graphical user interface object manipulations (e.g., drag and drop actions), establishing execution order of control objects through graphical user interface selection, designating distinct visual appearances for different types of connections, and automatically resizing attribute display elements in response to relocation of the element within...

Abstract

Enhancements to a strategy object editor for creating and modifying control strategies for process control systems (both distributed and discrete) is described. The improvements include: supporting a set of graphical depictions for individual control object (modified by an appearance object editor), drag and drop connections for declarations that connect control strategies to other control strategies, GUI-based designation of object execution order, automatically applied line styles based upon connection data type, and automatic modification of elements within an appearance object to accommodate a moved attribute.
