Changeover of base screen (changeover from PLC)

The screen No. of a screen to be displayed can be specified using the current value of a word
device (D, T or C) in the PLC.
The word device can be set in "Change Screen" in "Common Setting" in the screen creation
software. By performing this setting only once, a screen to be displayed next can be specified
from the PLC for any screen because the setting is effective to all screens.

Word device used to specify the base screen
If a word device used to specify the base screen, is not located in the battery backup area
(keep area, latch area), when the power of the PLC is turned off or when the PLC becomes the
stop status, the current value of the word device becomes 0. In this case, the error message
"DISPLAY SCREEN IS NOT AVAILABLE." is displayed because the user screen starts from
the screen No. 1. It is recommended to use a word device in the battery backup area.
