摘要:
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 organizational model of a hierarchical system can be distributed across various elements of an enterprise. Such elements include representations of the system that are maintained on higher-level business servers and other representations that serve control elements of the system such as programmable logic controllers and/or other industrial control components. In one aspect, an industrial automation system is provided. The system includes at least one controller to instantiate a portion of an organizational hierarchy. A communications component in the controller interacts with at least one other portion of the organizational hierarchy to facilitate data exchange and control between various components of an enterprise.

A serial optical data transmission system is provided. The serial optical data transmission system includes a displaceable optical pathway disposed adjacent to a slot configured to receive a first monitoring and/or control module. The optical pathway is biased towards a serial optical data bus position for transmission of optical data to or from at least one second monitoring and/or control module when the first monitoring and/or control module is removed from the slot. Further, the optical pathway is displaced from the serial optical data bus position when the first monitoring and/or control module is in the slot.
摘要:
A simulation environment for running a process simulation used to validate an industrial control program. The simulation environment exposes the I/O module configurations defined in the control program and retrieves module configuration information therefrom. This I/O module configuration information is combined with generic, module-specific I/O module profiles to create a pool of available controller I/O points, which can be selectively associated with I/O points in the simulation to create an I/O point mapping. During control program validation, simulated I/O data is exchanged between the process simulation and the I/O module instances in the controller in accordance with the I/O point mapping.

A new industrial control system and method are disclosed allowing for communication between multiple control devices of the system and remote devices via the Internet. The system includes a web access interface that is capable of being coupled to the remote devices via the Internet, and is coupled to the control devices by way of a network. A program executed by the interface receives an Internet signal having socket API data and formatted in accordance with the TCP/IP protocol, and extracts the data from the Internet signal. Another program executed by the interface receives the data and transmits a network signal, which includes the data but is not formatted in accordance with the TCP/IP protocol, to an appropriate one of the control devices, each of which has a respective web server program. The data is processed by the server program at the appropriate control device.

Systems and methods are provided for communicating with control objects according to a singular and unified address space. In one aspect, an industrial communications system is provided. The system includes a global address protocol that can be employed to communicate with local or remote networks. An industrial protocol is adapted to interface with the global address protocol, where a network component communicates with one or more control components via the industrial protocol and in accordance with an address supplied by the global address protocol.

Aspects describe creation of autonomous control for a composite curing process. Other aspects describe an intelligent industrial controller that can utilize a control model and a supervisory model to autonomously control the composite curing process. The control model can include intelligent agents corresponding to the physical elements of the composite curing process arranged in a hierarchical manner. For example, an autoclave agent can correspond to the autoclave, and the autoclave agent can be superior to a plurality of thermocouple agents corresponding to a plurality of thermocouples in a one-to-one fashion. The supervisory model can include diagnostic aspects for the composite curing process. For example, the supervisory model can be a finite element model of heat distribution on the surface of a composite material inside the autoclave. Based on a comparison between temperatures from the thermocouple agents and results of the supervisory mode, a malfunctioning thermocouple can be determined and eliminated.

The claimed subject matter provides a system and/or method that facilitates utilizing metadata appended to data related to an industrial automation environment with a controller that is associated with a hierarchically structured data model. An interface component can facilitate receipt of data associated with at least one of an instruction set, a configuration, and a collection. An append component can affix metadata to at least one of the instruction set, the configuration, and the collection, wherein the metadata conforms to a hierarchically structured data model.

An industrial control system includes a plurality of control devices providing control signals to direct an industrial process and a web access module including a web server, an Internet interface and a control network interface. Each of the control devices includes web page data concerning a respective web page associated with the respective control device. The Internet interface is couplable to a remote device via the Internet, and the control network interface is coupled to the control devices. The web access module is able to receive requests from the remote device to access the web pages associated with the control devices. In response to the requests, the web access module obtains the web page data concerning the web pages for which access has been requested, processes the data at the server, and sends data signals related to the data onto the Internet to be received by the remote device.
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.
