摘要:
Aspects describe an apparatus, method and system for constructing an application in an industrial automation system. An identification component can receive at least one requirement of the application. Based upon the at least one requirement, the identification component can select at least one service that satisfies the at least one requirement. The at least one service can be associated with at least one operational requirement. The identification component can match at least one host to the at least one service by matching the at least one operational requirement with at least one capability of the at least one service.

An industrial control configuration can be a dynamic entity where different controllers are added, are subtracted, fail, etc. When dynamic functions occur, bindings of the configuration can benefit from a modification. Therefore, automatic adjustment of bindings can occur to facilitate improved operation. Automatic adjustment can be practiced when the industrial control configuration is a distributed control configuration without reliance upon a central database.

Methods and apparatus for redundancy in machine or process control systems provide redundant communication adapters located with the groups of I/O modules, so that if the first communication adapter faults or becomes unavailable, a second communication adapter will perform all of the necessary functions of the first adapter. The adapters are connected to a multiplexing module for communicating input data from the I/O modules to the communication adapters, for exchanging initialization data with the first communication adapter and the second communication adapter to initialize the redundant mode of operation and for monitoring communication of the first communication adapter and the second communication adapter on the network to start up the second adapter as the primary adapter for communicating both input data and output data with the I/O modules.
摘要:
Systems and methods that vary multiple data sampling rates, to collect sets of data with different levels of granularity for an industrial system. The data for such industrial system includes sets of data from the “internal” data stream(s) (e.g., history data collected from an industrial unit) and sets of data from an “external” (e.g., traffic data on network services) data stream(s), based in part on the criticality/importance criteria assigned to each collection stage. Each set of data can be assigned its own unique data collection rate. For example, a higher sample rate can be employed when collecting data from the network during an operation stage that is deemed more critical (e.g., dynamic attribution of predetermined importance factors) than the rest of the operation.

Systems and methods that manage resources and distribution thereof within an industrial system. Such an automated and dynamic allocation service can allocate resources from pools of resources available to the industrial system, and hence supply an efficient operation (e.g., adding/subtracting resources dynamically based on usage). A plurality of allocation rules and/or algorithms for resource types can be predetermined, and/or dynamically trained by the allocation service. The data employed for the industrial system includes sets of data from the “internal” data stream(s) (e.g., history data collected from an industrial unit) and sets of data from an “external” (e.g., traffic data on network services) data stream(s), based in part on the criticality/importance criteria assigned to each collection stage.
摘要:
Systems and methods that correlate among disparate pieces of synchronized data, collected from an “internal” data stream (e.g., history data collected from an industrial unit) and an “external” data stream (e.g., traffic data on network services). A process trend component that determines/predicts an outcome of an industrial process and facilitates diagnostics/prognostics of an industrial system. Accordingly, relations among various parameters can be discovered (e.g., dynamically) and proper corrective adjustments supplied to the industrial process. Such enables a tight control and short reaction time to process parameters, and for a modification thereof.
摘要:
A microelectromechanical systems (MEMS) Device manufactured on a microscopic scale using integrated circuit techniques provides a sensitive magnetic field sensor by detecting motion caused by the Lorentz force produced by a current through a MEMS conductor. The resulting MEMS may be used as a component in a variety of devices including current sensors and proximity sensors.
摘要:
A microelectricalmechanical system (MEMS) digital isolator may be created in which an actuator such as an electrostatic motor drives a beam against a predefined force set, for example, by another electrostatic motor. When the threshold of the opposing force is overcome, motion of the beam may be sensed by a sensor also attached to the beam. The beam itself is electrically isolated between the locations of the actuator and the sensor. The structure may be incorporated into integrated circuits to provide on-chip isolation.
摘要:
A method is presented for fabricating an electrically isolated MEMS device having a conductive outer MEMS element, and an inner movable MEMS element spaced apart from the conductive outer MEMS element. The inner element includes a nonconductive base having a plurality of conductive structures extending therefrom. The conductive components are formed by plating a conductive material into a pre-formed mold which defines the shape of the conductor.
摘要:
Low voltage logic circuitry is used to permit an entire subsystem of an industrial controller to be placed within a hazardous environment to receive a high speed serial link and undertake the control of multiple control points without expensive and awkward long cable runs and electrically isolating circuits for each cable run. Energy and bandwidth limiting on the high speed link allows power levels commensurate with high data rates yet intrinsic safety of the media allowing it to freely pass in and out of the hazardous area. A mixture of intrinsically safe and non-intrinsically safe equipment on the same logical rack is allowed through a bus isolator providing isolated data communication in backplane fashion between modules while wholly isolating power transmission along the backplane.
