FP2 S−LINK Unit
3.1
An Overview of I/O Assignments
The S−LINK unit, like other I/O units, is used by assigning inputs (X) and outputs (Y).
The inputs/outputs on the FP2 side that result from these assignments are treated as
corresponding to the I/O addresses (S−LINK I/O devices) in the S−LINK.
Example:
The illustration below shows an example of the relationship
between the addresses in the S−LINK I/O device and the
addresses assigned to the S−LINK unit.
X10 to X2F
Y30 to Y4F
Contents of the illustration: Power supply unit, standard CPU,
16−point input unit, S−LINK unit installed beside these. I/O
numbers assigned to the S−LINK unit are X10 to X 2F (32
points) and Y30 to Y4F (32 points). Addresses on the S−LINK
are input (0 to 31) and output (32 to 63).
Notes
•
Setting contents selected with the I/O setting switch are read
only the one time, when the power supply to the FP2 is turned
on.

For detailed information pertaining to the S−LINK, refer to the
"S−LINK Construction Manual."
