摘要:
In an industrial control system, a relatively large number of bindings can permeate between different controllers. As a modification is made in a primary binding, supplemental bindings can be impacted and can become erroneous. The supplemental bindings can be automatically resolved such that they are no longer erroneous. Resolution can take place through access of a distributed directory that holds information related to the different controllers. To lower a likelihood of control system error or failure, the primary binding and supplemental binding can be placed online in synchronization.

The subject invention relates to systems and methods that distribute electronic data, such as Electronic Product Code (EPC) data, obtained from RFID tags by Radio Frequency Identification (RFID) readers and/or servers to agents within an agent-based control system. The systems and methods employ a component that collects, filters, processes, and stores electronic product data. The component collects electronic product data through corresponding reader and/or server interfaces. This data can be filtered to accept particular electronic product data, processed to a format suitable to the agents, and stored. Such storage can include delineating the electronic product data across rows of a table by electronic product code and across columns of the table by various types of data. Upon receiving a subscription and/or request from an agent for electronic product data, the component can obtain and convey the information to the agent.

An industrial field device comprises an alarm generator component that creates an alarm relating to the industrial field device and a buffering component that selectively caches the alarm within a data repository. The field device can be an industrial controller or a network infrastructure device. The alarm created by the alarm generator component can be customized according to user information, including user preferences.

An alarm generation system within an industrial automation environment comprises a packaging component that packages contextual data together with an alarm. A provision component relays the packaged contextual data and the alarm to an appropriate device. Thus, customized alarms can be provided for certain recipients given particular situations.

A highly reliable industrial control system provides for the processing of redundant control signals on as little as a single serial network without overloading the network by preprocessing input signals for coincidence and sending only the coincidence signal either periodically or on a change of state. Further compression of sent data is realized by extracting a reduced subset of transmission states from the input signals and transmitting only the transmission states.

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.

The subject disclosure pertains to transparent communications in an industrial automation environment amongst automation system components and IT systems. Systems and methods are provided that send and receive data to, from and amongst automation devices and transactional based IT systems. The system is viewed as a control system to the automation device and as a transactional system to the IT system. Accordingly, it is not necessary to provide a custom interface between automation devices and the IT systems.

A configuration tool provides a user interface that interacts with a gateway to remotely configure and/or monitor automation devices in an automation network. The configuration tool employs a self-contained software application (e.g., applet) that can be utilized for presentation and configuration interactions within a common web browser. The configuration tool can be based on open standards and implemented with small devices and/or with heterogeneous automation networks. The configuration tool can provide a list of automation devices to a system engineer via a workstation and standard software (e.g., a PC with a browser). The configuration tool interacts with automation devices to obtain their configurable parameters and/or send configuration commands. In one instance, the configuration tool and the automation network devices are based on Java and IEC 61499, respectively.
摘要:
An industrial controller module (13a) is provided with a routine of program instructions (29a) for storing a log of I/O table state changes (31) in a defined portion of memory (23). Upon the occurrence of a trigger event, a file of the state changes (37) is saved in the memory (23). Each entry (32) in the log of I/O table state changes (31) includes a timestamp (33) and values of each word of I/O state data (36) that changed at a time of the timestamp. Logs of state change data (16a), including timestamp data, can also be saved for intelligent sensors and actuators (16) and uploaded with the log of controller processor state data (31) to a computer (20) with a diagnostic program (21a) for playing back the state changes and synchronizing changes of the intelligent sensors and actuators (16) with changes of the controller processor module (13a).
