Abstract: A method for heterogeneous execution engines in a network centric process control system. The network centric process control system includes a plurality of nodes and each node includes one or more control service components, a middleware service component, a middleware API subcomponent, an address space subcomponent, and a communication component, where each control service component, middleware service component, and communication component is a separate executable running in a separate operating system process as provided by a real time operating system of each node. The method is performed by the network centric process control system, and includes identifying, by the communication component, a component of a node of the network centric process control system by an indication of a namespace ID of the component, forwarding, by the communication component, a request to the address space subcomponent of the identified component, wherein an item ID for runtime data of the identified component indicates an entity in the address space corresponding to the runtime data, and sending, by the communication component, an entity value, wherein the entity value corresponds to the requested runtime data. A network centric process control system, a computer program, and a computer program product for heterogeneous execution engines are also presented.

Abstract: A method for controlling an industrial process includes providing process data of the industrial process to an active instance of a control software as input, based on this input, updating an internal state of the active instance of the control software that is characterized by a set of internal variables of this active instance; based on this updated internal state, determining an output signal and outputting this output signal to at least one piece of equipment that is configured to alter a state, and/or a behavior, of the industrial process. The method further includes providing a prioritized subset of the internal variables that characterize the state of the active instance to at least one further instance of a control software that is configured to take over control of the industrial process in case of a failure and/or malfunction of the active instance.

Abstract: A method performed by a deploy service for coordinated deploy to RT services in an automation system. The method includes, from each of a plurality of engineering services, obtaining at least one configuration collection, each configuration collection being addressed to a specific one of the RT services. The method also includes forwarding each of the obtained configuration collections to the RT service to which it is addressed. The method also includes, for each of the configuration collections, in response to the forwarding thereof, receiving an acknowledgement from the RT service to which it was forwarded, indicating that the RT service is able to apply the configuration collection. The method also includes, in response to receiving the acknowledgements for all of the configuration collections, instructing each of the RT services from which the acknowledgements were received to apply the configuration collections.

Abstract: A method for dynamic load balancing between nodes in a network centric process control system. The network centric process control system includes a plurality of nodes and each node includes control service components, where each control service component is a separate executable running in a separate operating system process as provided by a real time operating system of each node. The method is performed by a node manager of a node, and the method includes negotiating a load balancing master role between the plurality of nodes, wherein the negotiating is based on an indication of the plurality of nodes representing load balancing cluster nodes, subscribing, in the negotiated load balancing master role, to a load balancing information from nodes of the load balancing cluster nodes, and reallocating, in the negotiated load balancing master role, one or more control logic tasks from one node to another node of the plurality of nodes based on the subscribed load balancing information. A node manager, a computer program, and a computer program product thereof are also presented.

Abstract: A provided mechanism for online firmware upgrade of a node in a process control system. The node includes components. Each component is a separate executable running in a separate operating system process as provided by a real time operating system of the node. A method is performed by a node manager of the node to be upgraded. The method includes creating a new component for each of the at least one of the components to be upgraded such that each new component is implementing a part of the firmware upgrade corresponding to its component to be upgraded, and where each new component is a separate executable running in a separate operating system process. The method includes synchronizing runtime data in each new component with runtime data of its corresponding component to be upgraded. The method includes replacing the at least one component to be upgraded with its new component and thereby upgrading the node.
