Embodiment Construction
[0034] Various aspects of the disclosure now are described more fully hereinafter with reference to the accompanying drawings, in which certain embodiments of the invention are shown.
[0035] These aspects may, however, be presented in many different forms and should not be construed as limiting; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of all aspects of the invention to Those skilled in the art. Throughout the specification, the same reference numerals denote the same elements.
[0036] in such as figure 1 In the architecture of the network-centric process control system 100 shown in the logical topology of FIG. Engineering tools for IO and device configuration deploy configuration data to IO and devices without touching the controller. The controller is focused on the execution of control logic and has access to IO signals from any IO or device in the system. The netwo...

The invention relates to 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, wherein 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 systemby 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.
Description
technical field [0001] The present disclosure relates to a method for heterogeneous execution, a network-centric process control system, a computer program, and a computer program product. Background technique [0002] Process controllers today typically only execute control logic and control logic libraries developed for that particular controller type. Each controller type has a specific control engine, the type used to execute its control logic. [0003] Data exchange between different types of controllers (for example, access to IO data connected to another controller) requires engineering of controller-to-controller communication. This is only possible if both controllers support the communication protocol. The setup of controller-to-controller communication has costs in terms of additional engineering work. Contents of the invention [0004] One object is to enable a reduction of engineering effort in the process control system. [0005] According to a first aspe...
