Overview of Communication
•
As shown in the diagram below, when a general-purpose computer communicates with the S8 series, the
general-purpose computer acts as the host and the S8 series acts as the slave.
•
Switch, lamp, data display, etc., are allocated within the internal user memory ($u0 to 32767). Assign memory addresses
for system, lamp, data display, and mode within this range.
•
When a screen number is specified from the host, a write action takes place to the internal memory address specified for
the screen. When a screen is changed internally by a switch, etc., the changed screen number is read, and written in the
internal memory address specified for the screen.
