Abstract:
A function block used in another process control system is previously associated with an data item by taking the function block being as data on a same rank as the data item. A definition-information generating section previously generates definition information about the function block associated with the data item, depending upon OPC browse information. An information-processing executing section executes a predetermined information processing by use of the association and the definition information.
Abstract:
Example methods and apparatus to manage module run sequences in a process control environment are disclosed. A disclosed example method includes receiving a module including a plurality of function blocks, receiving an indication of a subset of the plurality of function blocks, and receiving an indication of a first sequence of execution for the subset, wherein the first sequence of execution is different than a second sequence of execution associated with the module. The example method also includes associating the subset with a run sequence identifier, and associating the run sequence identifier with a trigger condition.
Abstract:
A process control routine may include a first internal function block for executing a control operation based on an input signal and an information conduit communicatively connected to the first internal function block. The information conduit may have an output adapted to provide the input signal to the first internal function block. The process control routine may further include an external function block communicatively connected to the information conduit and adapted to generate the input signal such that the output signal is directly provided to the information conduit prior to the execution of the control operation.
Abstract:
System and method for distributed execution of a graphical program. A graphical program is displayed on a display of a computer system. Targeted execution of a first graphical program portion of the graphical program on an execution target is graphically specified. The graphical specification includes displaying a visual indication of the specified targeted execution on the display of the graphical program. During execution of the graphical program, the first graphical program portion executes on the specified execution target and a remainder of the graphical program executes on a default execution target.
Abstract:
System and method for distributed execution of a graphical program. First and second icons associated with respective execution targets are displayed on a display. Each icon has an interior and specifies execution of a respective graphical program portion positioned in the interior of the icon on the respective execution target. First and second graphical program portions are respectively displayed in the interiors of the first and second icons, where each graphical program portion comprises a respective one or more interconnected nodes that visually indicate functionality of the graphical program portion. One or more wires connecting the first graphical program portion and the second graphical program portion are display. During execution of the graphical program, the first and second graphical program portions execute respectively on the first and second execution targets, and the first graphical program portion and the second graphical program portion communicate as specified by the one or more wires.

Abstract:
An apparatus includes a memory capable of storing information defining multiple function block types. A combination of instances of one or more function block types is capable of implementing a control process in a controller within a process control system. The apparatus also includes a function block editor capable of allowing a user to dynamically create or modify one or more of the function block types using a graphical user interface. The function block editor is capable of allowing the user to define one or more parameters for a function block type being created or modified.
