(1) Screen switching device settings
With the screen switching device, refer to the following to set the devices to be used.
(a) GOT internal device (GD)
It is recommended to use a GD device when screens are not switched by a PLC CPU.
Switch between screens with a specific touch switch ([Go To Screen Switch]).
With the screen switching device, the internal device (GD100) is set by default.
(b) PLC CPU device (D,W, etc.)
It is recommended to use this device to control screen switching from the PLC CPU.
Screen switching can also be performed by the touch switch (screen switching switch).
(2) GOT internal devices
They are devices kept in the internal of GOT.
The internal devices of GOT are classified into the following types.
• GOT bit register (GB)
• GOT data register (GD)
• GOT special register (GS) :
(3) Using an overlap window as the system window
System window includes test windows, remote screens of the remote personal computer operation (Ethernet),
and window screens which are used for system applications.
Use the system window by assigning any overlap window.
You can also display the window screen with an overlap window for which the system window is assigned
when the system window is not used.
If the system window is called while a window screen is displayed with the overlap window, the GOT closes
that window screen and opens that system window.
After the system window is closed, the window screen whose screen No. is the same as the value of the
screen switching device is displayed again.
Example) Switching between a system window and a window screen
(Overlap window 1 is used as the system window and D200 is set for the screen switching device.)
Touch the touch switch for
starting the test window.

: Bit register located inside the GOT and used as bit devices.
: Data register located inside the GOT and used as word devices.
Special register located inside the GOT, which stores internal information,
communication status error information, etc.
By monitoring GS with the object function, various information of the GOT
can be checked.
Writing values by a user, controls the GOT operations.
The GOT closes the displayed
window screen and opens the
system window.
