Abstract: To provide search capabilities in a process control system, a contextual knowledge repository is generated that organizes process plant-related data according to semantic relations between the process plant-related data and the process plant entities. When a user submits a process plant search query related to process plant entities within a process plant, search results are obtained by identifying a data set from the contextual knowledge repository which is responsive to the process plant search query. The search results are then presented on a user interface device based on the identified data set. To allow for searches to be performed by user interface devices external to the process plant, a data diode is disposed between a field-facing component and an edge-facing component of the process plant so that data flows from the field-facing component to the edge-facing component without flowing from the edge-facing component to the field-facing component.

Abstract: A Multi-Purpose Dynamic Simulation and run-time Control platform includes a virtual process environment coupled to a physical process environment, where components/nodes of the virtual and physical process environments cooperate to dynamically perform run-time process control of an industrial process plant and/or simulations thereof. Virtual components may include virtual run-time nodes and/or simulated nodes. The MPDSC includes an I/O Switch which delivers I/O data between virtual and/or physical nodes, e.g., by using publish/subscribe mechanisms, thereby virtualizing physical I/O process data delivery. Nodes serviced by the I/O Switch may include respective component behavior modules that are unaware as to whether or not they are being utilized on a virtual or physical node. Simulations may be performed in real-time and even in conjunction with run-time operations of the plant, and/or simulations may be manipulated as desired (speed, values, administration, etc.).

Abstract: An edge gateway system securely delivers and exposes data generated by and/or related to a process plant for consumption by external systems, and includes a field-facing component that sends, to an edge-facing component of the system, a collection of data types defined based on configurations of the process plant and represented using a syntax that is native to the one or more external systems. The field-facing component streams process plant-related content data indicated by one or more interest lists to the edge-facing component, where the streamed data is expressed using the collection of data types. Each interest list may include multiple types of data (e.g., control, I/O, diagnostic, device, historical, etc.) that collectively represent a particular named entity of the plant. Accordingly, the streamed data is securely delivered and exposed, via the edge-facing component, to the external systems.

Abstract: Process control systems for operating process plants are disclosed herein. The process control systems include control modules that are decoupled from the I/O architecture of the process plants using signal objects or generic shadow blocks. This decoupling is effected by using the signal objects or generic shadow blocks to manage at least part of the communication between the control modules and the field devices. Signal objects may convert between protocols used by control modules and field devices, thus decoupling the control modules from the I/O architecture. Generic shadow blocks may be automatically configured to mimic the operation of field devices within a controller executing the control modules, thus partially decoupling the control modules from the I/O architecture by using the shadow blocks to manage communication between the control modules and the field devices.

Abstract: A digital safety lock of a field device or other process plant equipment activates in response to receiving a request from a locking party, thereby placing the device into a locked mode. While the device is in the locked mode, only the locking party may perform maintenance activities on, or otherwise functionally control, the device. While locked, the device may provide an indication of the locking party to any other device or application attempting to access or control the locked device. Other devices, applications, and users may communicate with the locking party or locking party device to request that the device be unlocked and/or to request the corresponding digital safety lock key. Upon the device receiving the correct digital safety lock key, the digital safety lock may be deactivated, and the device may enter into an unlocked state if no other digital safety locks remain activated for the device.

Abstract: Graphical user interface (GUI) based systems and methods are disclosed for regionizing full-size process plant displays for rendering on mobile user interface devices. A regionizer application receives a full-size process plant display that graphically represents at least a portion of a process plant that includes graphic representations of a plurality of process plant entities. The regionizer app determines display region(s) of the full-size process plant display that define corresponding view portions of the full-size process plant display. The display regions are transmitted to a mobile user interface device for rendering by a mobile display navigation app. The GUI based systems and methods can also automatically detect graphical process control loop display portions within full-size process plant displays for rendering on mobile user interface devices.

Abstract: A system and method of performing communications over a communications network that uses a communication protocol having multiple different versions, provides for backwards compatibility when devices that support a higher or more secure version of the communication protocol are added to a network having devices that only support a lower or less secure version of the communication protocol. The system and method includes a technique of negotiating and establishing security procedures to be implemented in a communication connection between two devices on the network based on initial session request messages that indicate the version of the communication protocol supported by one or both of the devices. This system and method enable higher and lower protocol version devices (i.e.

Abstract: User interface sessions in a user interface device are initiated or resumed according to stored state data. A session request is received from a first client device. A user profile associated with the session request is identified and a determination made as to whether a previous session exists. If no previous session exists, a new session is instantiated using a default session configuration. If a previous session exists, a new session is instantiated according to the previous session.

Abstract: A gateway system securely delivers and exposes data generated by and/or related to a process plant for consumption by external systems, and includes an edge-facing component that receives process plant-related data from a process plant via a field-facing component of the system. The received data may comport with an exposable data type system utilizing a syntax known to the external systems. The edge-facing component stores the received data in a data lake, and mines the data lake to thereby discover relationships between stored data points. Indications of the received data and the discovered interrelationships are stored in a contextualized process plant knowledge repository, such as a graph database, that is accessible to the external systems and other systems and applications via one or more access mechanisms, which may include utilities, services, servers, and/or applications. Some of the access mechanisms allow external applications to be installed at the edge-facing component.

Abstract: An I/O server service interacts with multiple containerized controller services each implementing the same control routine to control the same portion of the same plant. The I/O server service may provide the same controller inputs to each of the containerized controller services (e.g., representing measurements obtained by field devices and transmitted by the field devices to the I/O server service). Each containerized controller service executes the same control routine to generate a set of controller outputs. The I/O server service receives each set of controller outputs and forwards an “active” set to the appropriate field devices. The I/O server service and other services, such as an orchestrator service, may continuously evaluate performance and resource utilization in the control system, and may dynamically activate and deactivate controller services as appropriate.
