Abstract: In example embodiments, a shortest path first-based isolation trace function is provided to determines what switchable elements need to be closed to stop flow of a quality to a location in an infrastructure model arranged as a network. The shortest path first-based isolation trace function may perform shortest-path traces from the location to each source. For each successful shortest-path trace finding one or more switchable elements, the first switchable element encountered on the path of the trace is added to a solution set, and marked as active to prevent further traversal in subsequent shortest-path traces. When all the shortest-path traces are complete, the solution set may be returned as a result. If no switchable element is found on a path of one of the shortest-path traces, it may be concluded that the location cannot be isolated and such conclusion returned as the result instead of the solution set.

Abstract: Techniques for embedding a web browser in a graphical display view of a process plant include presenting a graphical display view including (i) indications of one or more process control elements, such as a control module, a function block, a process plant entity, or a process section of the process plant, and (ii) a web browser having web content from a source address. The web browser is presented according to one or several presentation parameters, such as such as a size and position of the web browser within the display view. Furthermore, the presentation parameters include restrictions on functions performed within the web browser, such as a sandbox or sandbox attributes. The presentation parameters also include a source whitelist that specifies web addresses which are allowed to be set as the source address for presenting web content.
