A multi-platform industrial search system facilitates indexing and searching of plant-wide data residing on multiple different data platforms. The industrial search system automatically inventories industrial devices and other data sources located throughout a plant, and identifies available data items on each data source. The search system indexes the discovered data items in a federated data model that can subsequently be searched to locate data items or tags of interest. The federated data model records references to data items found on different types of data sources, including but not limited to industrial controller programs, human-machine interface applications, data historians, device documentation stores, inventory tracking systems, and other such data sources. The search system can also initiate automated searches of the federated data model in response to detected performance issues and deliver notifications and contextual information to plant personnel.

Systems, methods and apparatus for bidirectional network geography delivery are disclosed. The methods include receiving a reference subnet network geography from a main network device, storing the received reference subnet network geography, retrieving an actual subnet network geography of a subnet network, comparing the reference subnet network geography to the actual subnet network geography and determining if they are compatible, and commissioning the subnet network based on the received reference subnet network geography when the received reference subnet network geography is compatible with the actual subnet network geography of the subnet network. The methods also include retrieving an actual subnet network geography of a subnet and sending it a main network device, causing it to become a new reference subnet network geography and sending the new reference subnet network geography to a main network device.

This invention relates to an apparatus and method for output current control in an Industrial Process Control System. The output module comprises two management units each of which calculates the current demand for the module independently from one another. One management unit controls an output current controller whilst the other unit monitors the current produced by the output current controller against an independently calculated demand. The output module has multiple output modules. However rather than one module providing a backup for the other modules, or alternating between use of each module, in normal operation, each module provides a portion of the required output current, the total output current being equal to the sum of the currents output by each module. In the event of failure on one of the modules, the other module or modules switch to providing the total current required and the failed module is switched to a fail safe mode by using an isolation circuit to switch off the output current from that module.

Cloud-based data processing services facilitate collection and processing of industrial data in a cloud platform. On-premise data collection agents collect and pre-process industrial data from one or more data sources, including industrial devices, historians, etc. The agents apply a header to the data defining a hierarchical, customer-specific data model that can be leveraged in the cloud platform to suitably process the data. Cloud-side data process services receive the resulting data packets, assign the data to one or more priority queues, and invoke a manifest assembly corresponding to the data model defined by the header. The manifest assembly defines one or more operations to be performed on the received data, including specifying a final storage destination for the data, determining one or more metrics for an industrial system or process based on the received data, or other such operations.

A cloud gateway device facilitates collection of industrial data from one or more data sources on the plant floor and migration of the collected data to a cloud platform for storage and processing. The cloud gateway device collects historical, live, and/or alarm data directly from industrial devices networked to the gateway device, formats and encapsulates the data with customer-specific header information, and sends the resulting data packets to a cloud platform for processing by cloud-level analytics services. To keep local memory requirements low, the cloud gateway device supports store-and-forward functionality in the event of a communication loss to the cloud platform, whereby the collected industrial data is redirected to an external data storage repository until communication to the cloud platform is reestablished.

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.
