Step a: Screen change according to read area “n + 2”
Step b: Screen change with an internal switch
Step c: Screen change to the same screen number as step 1 according to read area “n + 2”
In this case, however, the same value is stored in read area “n + 2” so the command is not valid. In such a case, it is possible to forcibly
switch the screen to the screen number contained in read area “n + 2” at the leading edge [0

*1 Screen No. Error
When MONITOUCH has started communications with the PLC, the screen of the screen number specified in read area “n + 2” is
displayed. If the screen number specified in read area “n + 2” does not exist in the screen data, “Screen No. Error” is displayed on
MONITOUCH.
Before starting communications with the PLC, check the data in [Read Area] “n + 2” and confirm that the screen number to be displayed
at first is specified.

These bits are used for switching the screen by an external command.

Even if the screen has been switched using an internal switch, it is possible to switch the screen using
an external command from the PLC. External commands have priority over internal switches.
