    摘要: Techniques for physically removing and replacing a simplex I/O component include plant personnel placing the component into a “REPLACEABLE” state via a user interface of the component. In response, the simplex I/O component informs the I/O subsystem thereof. The I/O subsystem stores a record of the component's REPLACEABLE state and begins to hold data values (e.g., field device values) most recently received from the component. When the I/O subsystem detects that the simplex I/O component is uncommunicative (e.g., due to being removed and replaced), based on the stored record of the “REPLACEABLE” state, the I/O subsystem retrieves the most recently received held data value and transmits it to a controller, thereby maintaining controlled (e.g., non-disruptive) execution of a control loop. When the replacement simplex I/O component initializes to an “IN-SERVICE” state, the I/O subsystem updates its state record accordingly, and resumes forwarding live field data values to the controller.

    摘要: A highly versatile process control or factory automation field device is configured with an interface and communication connection structure and security features that enable the field device to operate as a data server that communicates with and supports multiple different applications or clients, either directly or indirectly, while simultaneously performing standard process and factory automation control functions in a highly secure manner. The security features include a root of trust component, a secure boot component, secure memory components, secure communication components, security audit components, secure provisioning components and endpoint identity components, making the field device communications and operations secure and trustworthy. Moreover, various different process control and factory automation network architectures and, in particular, communication architectures, support the versatile field device to enable the versatile field device to simultaneously communicate with multiple different client devices or applications (each associated with a different system) via a common communication network infrastructure in a very secure manner, using the same or different communication protocols.

    摘要: 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.). The platform simultaneously supports simulation and run-time operations and interactions/intersections therebetween.

    摘要: A set of discrete input/output (I/O) channels for one or more field devices may be grouped, organized, and connected to a field module device, which may connect to an electronic marshalling apparatus in a marshalling cabinet via an I/O channel. The field module acts as an intermediary, decoding messages received via the I/O channel to identify commands for discrete output (DO) channels that are then forwarded appropriately. The field module may also receive variable values carried by signals on discrete input (DI) channels and encode the values to a message that may be transmitted to the marshalling apparatus and controller, thus making the variable values on the DI channels available to the controller. The field module may store a profile including information that facilitates various smart commissioning techniques, including autosensing of tags, automatic tag binding, and automatic configuration of a control element corresponding to the field module.

    摘要: A method and system for publish-subscribe communication architecture for highly-versatile (HV) field devices in control and automation system implements reception at an HV field device, from a client device or application, of a message indicating a selection of one of a plurality of publish categories. The publish category corresponds to a type of information desired by the client device or application. The field device transmits to the client device or application an identification of each of a plurality of publish lists corresponding to the selected publish category, which publish lists are each stored on the field device and each include a set of parameters associated with the field device. The field device receives, from the client device or application, a selection of one of the publish lists identified by the field device, and transmits to the client device or application the set of parameters associated with the selected publish list.
