About Managing Memory for WindowViewer

You can configure how WindowViewer uses memory for windows and popup symbols to improve performance at run time. Windows and popup symbols displayed using ShowSymbol animation and the ShowGraphic script function can be kept in memory at run time in certain conditions to allow for fast retrieval.

In-memory caching of Industrial graphics is available only in Managed or Published InTouch applications. This capability is disabled in Standalone InTouch applications.

You can also specify the interval for a periodic memory health check and settings for the heap memory segment. Each time a new popup symbol opens, it triggers a memory health check regardless of the pre-set interval.

Fast switching to WindowViewer or from WindowViewer to WindowMaker clears both the graphic cache and the window memory cache.

For information on memory management for symbols displayed by the ShowGraphic function, see the Industrial Graphic Editor User Guide.
