A system of communicating data over a high availability industrial control system is disclosed. The industrial control system includes a first data producer, a second data producer in communicative connection with the first data producer, a first data consumer, and a second data consumer in communicative connection with the first data consumer. The system further includes the first producer communicating the data over multiple connection paths from the first producer to the first consumer and the second consumer through intermediate modules, and the second producer communicating the data over multiple connection paths from the second producer to the first consumer and the second consumer through intermediate modules. Also disclosed is a method of communicating data over the high availability industrial control system.

System and method of communicating data over high availability industrial control systems

Secure data transmission between an input device and both industrial controllers in a high-availability system utilizes a secure connection established between the primary industrial controller and the input device. Data required to establish the secure connection is stored on the primary controller as part of the connection data corresponding to the secure connection. The input device transmits data to the primary controller over the secure connection according to the desired level of security. The primary controller transmits the connection data defining the secure connection to the secondary controller. If a failure occurs in the primary controller, the secondary controller establishes a connection to the input device using the connection data for the secure connection, such that the secondary controller may assume responsibility for the controller end of the secure connection. The primary controller transmits the input signals to the secondary controller via the dedicated connection between controllers.

A method and system for interacting with data frames passing through a module connected to an industrial network is disclosed. Each module includes an aggregation unit located on the network interface above the physical layer. To transmit data, the aggregation unit reads a header from a dynamic data packet to determine if the module is a participant module for the packet. If so, the aggregation unit inserts data from the module into the data packet and transmits the packet to another module. To receive data, the aggregation unit reads a header from the data packet to determine whether the data packet includes data for the module. If so, the aggregation unit reads the data and passes the data packet to another module. If the aggregation unit determines that a data packet is not intended for the module, the data packet is passed to another module with no further interaction.

Method and system for data aggregation in an industrial communication protocol

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.

Correlation of non-times series events in industrial systems

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.

Adjustment of data collection rate based on anomaly detection

An interface between a network communication card and an industrial controller allows rapid asynchronous buffering using two buffers and two associated registers for each data direction. A reading of the buffers is proceeded by an attempt to copy from the write designation register to the read designation register checking the equality of the register values and then reading from the buffer designated by their common value. Conclusion of the reading sets the write destination register to zero. Writing of the buffers is proceeded by a checking of the read designation register for zero value and then writing to other than the last buffer indicated by the write designation register. If the read designation register is non-zero, then the writing occurs to the opposite buffer of that in the read designation register. The write designation register is then updated to indicate the buffer written to.

High aspect ratio filaments of magnetic material are randomly dispersed in a non-magnetic matrix such as paper or plastic for part of a critical component of a manufactured product to permit remote sensing of the manufactured product by the application of an external oscillating magnetic field and the detection of the resulting induced magnetization. The material may be incorporated into a wide variety of products that must be remotely sensed.
