3.1 An Overview of I/O Allocation

The S-LINK unit, like other I/O units, uses inputs (X) and outputs (Y).

The inputs/outputs on the FPΣ side are treated as corresponding to the I/O addresses (S-LINK devices)

in the S-LINK.

The illustration below shows an example of the relationship between the addresses in the S-LINK I/O

device and the addresses allocated to the S-LINK unit.

Contents of the illustration:

Control unit, S-LINK unit installed beside it.

I/O numbers allocated to the S-LINK unit are X100 to X11F (32 points) and Y100 to Y11F (32 points)

according to the I/O allocation of the FPΣ expansion unit.

Addresses on the S-LINK are input (0 to 31) and output (32 to 63).

Note:

• Setting contents selected with the I/O setting switch are read only the one time, when the power supply

to the FPΣ is turned on.

• For detailed information pertaining to the S-LINK, refer to the "S-LINK Design Manual".
