A method used for generating a zoomable diagram includes providing a topology diagram of at least a part of the industrial plant for interacting with components of the industrial plant; generating, for each zoom-level of the zoomable diagram, a zoomed diagram comprising a zoomed view of each one of the plurality of objects and connections, by applying at least following rules to each object: from a first predefined zoom-level, collapse all objects of a plant-segment to one object and keep only connections that cross the plant-segment's border, and introduce an plant-segment related alarm measure as a function of all alarm statuses of the plurality of objects of the plant-segment; and when interacting with the components of the industrial plant, determining, for each plant-segment, the plant-segment related alarm measure, and outputting the plant-segment related alarm measure for healing a cause of the alarm.

A display unit for a manually operated machine tool includes a display having windows and text each associated with and indicating positions of different axes of the manually operated machine tool which are manually adjustable. A memory stores configuration modes of the display including a stationary mode in which the windows and text provided in the display are each the same size and color, and at least one emphasis mode in which the window and/or text associated with one of the different axes is larger and/or a different color. A processor is configured to switch the display from using the stationary mode to using an emphasis mode based a position signal indicating that one of the different axes is being adjusted by manual operation of an operator such that the window and text associated with the axis being adjusted is emphasized on the display.

In responsive to receiving a user interaction with a map graphical user interface (GUI) of a client device, the system identifies an origin, and determines a map zoom level and map position based on the interaction. The system identifies and ranks candidate destinations for the origin. The system automatically selects destinations from the ranked candidates for inclusion in the map based on the zoom level and the position. Each selected destination for which a destination location indicator would be obscured in the map by an indicator of a higher ranked destination is automatically determined by the system. The system then deselects each destination for which a location indicator has been determined to be obscured by an indicator of a higher ranked destination, forming a revised set of destinations. The system transmits instructions to display a location indicator for each destination in the revised set to the client device.

An intrinsically-safe handheld field maintenance tool includes a controller, a process communication module, and a display. The process communication module is configured to communicate with a field device using a process communication protocol. The display is coupled to the controller. A user interface module is also coupled to the controller and is configured to receive user input. The controller is configured to detect a user input help request and provide a video output on the display in response to the user input help request.

Technologies relating to manipulating visual representations of data. A method is provided that includes displaying a first visual representation including a zoom parameter having a first value; receiving a first input while maintaining a first position of a cursor relative to the first visual representation; modifying the zoom parameter to have a second value, where the first visual representation of the document is adjusted according to the second value to provide a second visual representation; identifying a change in position of the cursor to a second position relative to the second visual representation; receiving a second input to modify the zoom parameter of the second visual representation; and modifying the zoom parameter to have a third value, where the second visual representation of the document is adjusted relative to the second position of the cursor according to the third value to provide a third visual representation of the document.

A display unit for a manually operated machine tool includes a display having windows and text each associated with and indicating positions of different axes of the manually operated machine tool which are manually adjustable. A memory stores configuration modes of the display including a stationary mode in which the windows and text provided in the display are each the same size and color, and at least one emphasis mode in which the window and/or text associated with one of the different axes is larger and/or a different color. A processor is configured to switch the display from using the stationary mode to using an emphasis mode based a position signal indicating that one of the different axes is being adjusted by manual operation of an operator such that the window and text associated with the axis being adjusted is emphasized on the display.

A handheld field maintenance tool includes a training mode. The handheld field maintenance tool has a process communication module operably coupleable to a field device, a user interface, and a controller coupled to the process communication module and the user interface. The controller is configured to interact with a user through the user interface, and is configured to provide a simulation function where at least one characteristic of the field device, indicated through the user interface, is generated by the controller instead of the field device.

A method includes displaying a plurality of windows in a graphical display. Each window corresponds to a representation of at least a portion of an industrial process system. The method also includes, responsive to a first window being in an active state, subscribing to first operational data associated with the process system. The method further includes, responsive to a second window being in an inactive state, unsubscribing from second operational data associated with the process system.

When a command for outputting a movement amount at a specific reference value is included in a command block, a numerical controller which controls a position of a control axis in synchronization with a reference value by using tabular data registers the reference value and the movement amount of the command in a shift table while associating the reference value with the movement amount. Then, when the current reference value reaches the reference value registered in the shift table, the numerical controller superposes the movement amount of the control axis that is associated with the reference value in the shift table on a distributed movement amount to the control axis, and outputs the superposed movement amount as a movement amount of the control axis.

An intrinsically-safe handheld field maintenance tool is provided. The tool includes a process communication module configured to communicate with a field device in accordance with a process industry communication protocol. A controller is coupled to the process communication module and is configured to provide at least one function related to maintenance of the field device. Program instructions embodied on a computer readable medium coupled to the controller, the program instructions causing the controller, when executed by the controller, to provide operator rounds functionality, CMMS/EAM functionality and/or ERP functionality.
