Appendix 6 Universal Serial Communications
Interface
Outline of Communication
As shown in the diagram above, when a general-purpose computer communicates with the V series,
the general-purpose computer acts as the host and the V series acts as the slave.
Switch, lamp, data display, etc., are allocated within the internal user memory ($u). When a screen
number is specified from the host, a write action takes place to the internal memory address specified
for the screen, and the specified screen is then displayed on the V series.
When a screen is changed internally by a switch, etc., the changed screen number is read, and written
in the memory specified for the screen.
