13.14 Indirect Window

The Indirect Window places a defined child window area over the current window. The Indirect Window's screens
are created the same as regular base windows. Usually their size is smaller than a full window. The Windows are
then displayed in the Indirect Window frame as called by a PLC data register. The limitation to the maximum
registered Indirect Windows on each screen is 500. However, at run time, only 5 windows at the most can be displayed
simultaneously on each screen.
