Example of screen changeover by data register

The "Change Screen" object is set for all screens (common setting).
- Common setting for all screens
The display is changed over to
a screen having the number
specified by a data register in
the PLC without using the
screen changeover condition.
• Immediately after the GOT has been put into screen
mode, screen No. 0 is always displayed.
When the sequence program shown below is
executed, the screen is changed over.
• Example of sequence program
• When screens will not be overlaid, enter "-1" to D1 and
D2.

Important point
• Combination of other types of screen changeover:
When screen changeover by data registers is used together with screen changeover by
another method (bit devices or touch keys), the priority is always given to screen
changeover by data registers ("PLC data register") if both "Control Input" and "Bit Device"
are not set because the changeover condition is not given.
When using different types of screen changeover together, refer to "19.7 Application of
screen changeover".
