Appendix 6 Universal Serial Communications App6-45
System Memory ($s)
System memory is memory that writes V series action status when the V Series is currently displaying
something.
With this written information, it is possible to check overlap status, buffer area, printer, backlight, and
slave station status in multi-drop connection mode.
* System memory cannot be read or written from the host computer.
In the table below, a small part ($s80 to 95) of system memory is extracted. For more information on
other areas of system memory, refer to Appendix 1 in the Reference Manual (Function).
