FUNCTION_BLOCK FbOpenDialog EXTENDS FbExecuteSingleVisuActionBase
Handles the action open dialog
To use this function block in the programm set the according inputvalues and start the dialog open action with xExecute = TRUE.
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.
