■2. Method for using the screen changing function
• As a feature of this function, monitor screens are created for each station number.
When the system switching occurs, the GOT can change the monitoring target to the control system PLC CPU on
the other monitor screen.
• To achieve this, the script of the GOT monitors the special relay SM1515 (Control system identification flag) of the
PLC CPU and stores the screen number corresponding to the latest station number of the control system into the
screen switching devices.

There are the following 8 different screen switching devices.Set the screen switching devices for all screens to be
used.
(1) Base screen switching device
(2) Overlap window 1 switching device
