S When the data is written from the host:
To switch, open, close or move a window on the NT31/NT31C by an instruction
from the host, write the window screen number or coordinates to the “window
No.”, “X coordinate” or “Y coordinate” as 4-digits BCD or hexadecimal. Whether
the values are BCD or hexadecimal is determined by the setting for numeral
storage type in the PT configuration settings made with the Support Tool.
By changing the “screen No.”, window can be switched, opened or closed.
It is possible to move the window position by changing the “X coordinate” and “Y
coordinate”.

S When the data is written from the NT31/NT31C:
When the display status of the window is changed by the operation at
NT31/NT31C, new window screen No. or coordinates is written to the “window
No.”, “X coordinate” or “Y coordinate” as 4-digits BCD or hexadecimal from the
NT31/NT31C. When the window is opened or closed, window open/close status
is written to the “window open status” (page 496) of “PT status” in PT notify area.
Whether the values are BCD or hexadecimal is determined by the setting for nu-
meral storage type in the PT configuration settings made with the Support Tool.
