A system and method for programming a plurality of agents onto a distributed control system are disclosed. The system includes a terminal that displays a graphical user interface having a plurality of images. The plurality of images includes a first image showing a plurality of selectable templates and at least a first mechanism by which first user input signals can be received concerning the templates, where the templates include agent-type programming, and a second image showing a representation of controllable devices and at least a second mechanism by which second user input signals can be received concerning associations between the templates and the representation. The system further includes a processing device that generates executable programming to be performed by the distributed control system based upon the templates and the associations, where the executable programming at least partly governs agent-type behavior of the distributed control system.

In an industrial control setting, different components can have information that can be valuable to various entities, such as other components, technicians, and the like. A decision can be made as to what information should be available to entities and a determination can be made if the information should be published in a directory or be discoverable. Security can be taken into account in determining if information should be published and decision making can employ adaptive learning, such that a publish and/or discovery decision criterion can be modified based on the learning.

The claimed subject matter provides a system and/or method that facilitates employing safety within an industrial environment. An enhancing component can implement at least one of a security level, authentication, authorization, or an access right to a validated action to at least one of the controller or the controller engine instance. The enhancing component can further separate two or more entities within the industrial environment, the first entity related to process control and the second entity related to process safety. Additionally, the enhancing component can employ at least one of a backup controller or a backup controller engine instance in the event of at least one of a software error or a hardware error within the industrial environment.

A system for troubleshooting control programs employs an event log that captures the values of inputs to outputs from the control program only at event times determined by changes in input or output data. The program allows the event log to be reviewed in jumps to only events which cause a change in output value of an instruction or particular change in output value of a particular instruction, greatly simplifying the troubleshooting process. The event log records a particular instruction instance associated with the event permitting the operation of the program to be studied in reverse order. The event log may also record a timestamp of the event allowing time stamped data from different devices to be synchronized with the review of the events.

Various amounts of information can be beneficial to different controllers configured upon an industrial control system. Information can be retained in a distributed directory such that controllers quickly learn information concerning other controllers. The distributed directory can be automatically constructed and populated with information from different controllers. When a module enters an industrial control system, information can automatically advertise to other units through use of the distributed directory.

The subject matter disclosed herein describes a method to allocate and prioritize data communications on an industrial control network. A transmission schedule including multiple priority windows and multiple queues is established. Each queue is assigned to at least one priority window, and each priority window may have multiple queues assigned thereto. A control device communicating on the control network transmits data packets according to the transmission schedule. Within each priority window, data packets corresponding to one of the queues assigned to the priority window may be transmitted. The data packets may be transmitted at any point during the priority window, but will only be transmitted if no data packet from a higher queue is waiting to be transmitted.

An alarm provision system comprises a recognizer component that receives an alarm/event and recognizes the alarm/event. A provision component analyzes hierarchical relationships associated with an industrial environment and automatically provides a subscribing entity with the alarm/event and at least one other alarm/event that is related to the received alarm/event, the provision of the at least one other alarm/event is based at least in part upon the analysis of the hierarchical relationships.

Systems and methods that efficiently simulate controlled systems are presented. A simulation management component (SMC) controls simulation of a controlled system by controlling a desired number of nodes, each comprising a controller (e.g., soft controller) and a simulated component or process, which are part of the controlled system. The simulation can be performed in a step-wise manner, wherein the simulation can comprise a desired number of steps of respectively desired lengths of time. For each step, the SMC dynamically selects a desired clock (e.g., currently identified slowest clock) as a master clock for the next step. The SMC predicts a length of time of the next step to facilitate setting a desired length of time for the next step based in part on the predicted length of time. As part of each step, components can synchronously exchange data via intra-node or inter-node connections to facilitate simulation.

An industrial control system and method of controlling an industrial process are disclosed herein. In at least one embodiment, the control system includes an order system configured to receive an order from an external source and process the order to generate an order instance in accordance with an order ontology, at least one database storing a plurality of selectable generalized production plans and information identifying capabilities of a plurality of control entities, and a product agent in at least indirect communication with the order system, the at least one database and the control entities. The product agent receives at least one portion of the order instance, selects at least one of the generalized production plans, and communicates with the control entities so as to determine a production plan instance suitable for governing at least one aspect of an industrial process in order to satisfy at least one portion of the received order corresponding to the at least one portion of the order instance.
摘要:
An improved industrial automation system and communication system for implementation therein, and related methods of operation, are described herein. In at least some embodiments, the improved communication system allows communication in the form of messages between modules in different control or enterprise domains. Further, in at least some embodiments, such communications are achieved by providing a communication system including a manufacturing service bus having two internal service busses with a bridge between the internal busses. Also, in at least some embodiments, a methodology of synchronous messaging is employed.
