Set view context

Users can select items from the Assets & Function Block Templates area of the PLCViewerApp window to set the context of a view. Also, users can select navigation items from a running ViewApp to set the context of a view. For more information about showing current PLC values of a ViewApp navigation item, see Navigation from a ViewApp.

The PLCViewerApp includes a set of navigational and context controls in a menu bar near the top of the window.

The Zoom In and Zoom Out controls at the left enable you to zoom in or out to show more or less detail in the view window.

The Back and Forward controls enable you to move between previously shown context views in your current session. For example, if you have looked at three views in the PLCViewerApp, selecting Back will show the second context view. Using Back and Forward controls eliminates the need to scroll through the Assets & Function Block Templates area to reselect an item to show its view again.

The Controller field provides a drop-down list of controllers whose source logic files were added to the PLCViewerApp while configuring data sources. The source logic file includes the controller's programs. The PLCViewerApp can only show program data from the selected controller during runtime.

The Scope field appears when selecting an add-on instruction to enable selecting a specific instance of an add-on instruction in the control for animation.
