A tracing apparatus that is connected to a PLC for inputting and outputting signals based on a ladder program includes: a ladder program analysis unit that analyzes an order in which nets in the ladder program are arranged so as to produce an execution order signal table indicating an order in which the nets are executed; a trace target setting unit that sets one or more nets to be traced; a trace data acquisition unit that acquires trace data in a predetermined sampling cycle; a compensation determination unit that determines, based on the table, whether or not the state (reference signal) of a signal at a contact included in a ladder circuit to be traced needs to be compensated for; and an output unit that outputs a ladder diagram of a trace result which has been compensated for based on the result of the determination of the compensation determination unit.

A control system for a technical plant includes an operator station server and one operator station client, wherein a data model is implemented on the operator station server and the operator station client has display and control units, where the operator station server transmits visualization information representing the data model to the display unit that generates a graphical presentation of the received visualization information for an operator of the control system, receives commands relating to the data model from the operator and forwards them to the control unit, and where the control unit receives the commands, generates revised visualization information and transmits this information directly to the display unit to adjust the graphical presentation of the display unit, generates adjustment commands from the received commands and transmits them directly to the data model on the operator station server to adjust the data model in response to the operator commands.

A method and system for managing engineering of an industrial device in a cloud computing environment is disclosed. The method includes receiving a request for performing an engineering action on at least one of the industrial devices. The method includes determining a control program block corresponding to the at least one of the industrial device based on the received request. Further, segmenting the determined control program block into one or more software units based on content of the control program block. Furthermore, processing the one or more software units based on one or more user requirements and the requested engineering action. Also, determining at least two instances of the industrial device for deploying the processed software units based on segment type of the processed software units. Moreover, deploying the respective software units into each of the determined at least two instances of the industrial device.

Example implementations may involve using a prompt to prevent inadvertent control or playback of audio content. When a mobile device receives input data indicating a command to play back audio content on a first playback device, the mobile device determines whether the mobile device is in proximity to the first playback device. If the mobile device determines that the mobile device within a given proximity to the first playback device, the mobile device transmits, via the network interface, one or more commands to instruct the first playback device to play back the audio content. However, if the mobile device determines that the mobile device outside the proximity, the mobile device displays a prompt indicating that the mobile device is the outside the given proximity to the first playback device and a selectable control that, when selected, transmits the one or more commands to play back the audio content.

An industrial integrated development environment (IDE) comprises a development interface that affords a user a great deal of control over the editing tools, workspace canvases, and project information rendered at a given time. The industrial IDE system automatically filters the tools, panels, and information available for selection based on a current project development task, such that a focused subset of editing tools relevant to a current development task or context are made available for selection while other tools are hidden. The development interface also allows the user to selectively render or hide selected tools or information from among the relevant, filtered set of tools. This can reduce or eliminate unnecessary clutter and aid in quickly and easily locating and selecting a desired editing function. The IDE's development interface can also conform to a structured organization of workspace canvases and panels that facilitates intuitive workflow.

A system provides a design interface for designing and implementing graphical user interfaces that users can access through web browsers. Depending on the configuration of the graphical user interfaces, the users may be able to monitor and control industrial processes by interacting with components that correspond to the industrial processes as displayed in user interfaces at client devices. The design interface includes functionality for selecting preprogrammed components, or for generating new components for display. The design interface further allows designers to associate data values received from a variety of sources with properties of the components in the user interfaces. In particular, properties associated with a component of an interface are stored in property tree structures, making dynamic changes to the components possible. Data bindings between subtrees representing components and sets of data from industrial and other sources allows for designs that scale with the availability of the data.

A system for efficiently configuring bindings based on a dependency graph is described. The system may generate or access a graph comprising a set of nodes. Each node may represent a binding and is associated with a component property of a component hierarchy corresponding to a hierarchical structure of a data model. Each node of the graph may be connected to at least one other node with an edge representing a dependency in the hierarchical structure of the data model. The system may receive a request to generate a view associated with the set of bindings. The system may determine an order to load the set of bindings based on the graph, and may load the set of bindings based on the determined order.

Exemplified herein is a graphical user interface for an industrial automation system that provides, in a single aggregated and eloquent view, a configuration workspace to discover and present configuration details of control components within an industrial automation system. These components may include industrial controllers, programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) systems, programmable automation controllers (PACs), and the like, which have modules (as well as submodules) connected thereto. Among other things, the configuration workspace enables a holistic view of identified hardware configuration and the modular reconciliation and troubleshoot of the network device and module configurations.

Methods and apparatus to virtualize a process control system are described. A described process control system includes a server cluster including one or more servers. When operating, the server cluster provides a virtual workstation or virtual server, a virtual controller to interoperate with the virtual workstation or server and to implement process control operations, and a virtual input/output device to interoperate with the virtual controller and coupled to one or more field devices within the process control system.
