Use the Computer to Display and Operate Data on the Display Unit

If you control the same PLC/device address in parts on multiple display units, it may not operate properly.
For example, if you set up the same address in the Data Block Display Graph's control word, even though you update the graph on the Master display unit the graph will update on Slave display units but not the Master display unit. To prevent this type of behavior, use a different address on each display unit.

In the [System Settings] window's [Display Unit] tab, if the [Screen Settings] area's [Reflect in Device/PLC] check box is selected, and the same items are used on Master and Slave display units, the [System Area Start Address] will be the same for all display units..
For example, if you make the change screen number common, all Master and Slave display units will synchronize their screen displays.

For mutilink feature of serial connection, please refer to Device/PLC Manual.
