FUNCTION_BLOCK FbChangeVisu EXTENDS FbExecuteSingleVisuActionBase
Changes the currently shown toplevel visualization
The fb-instance should be declarated within a permanent setting, e.g. a GVL, and not within a temporary setting, e.g. a function. Therefore, the action will still be available, when called, later on.
