6.4 I/O allocation

The external input signals are allocated to the external input devices/registers (X/XW).
The external output signals are allocated to the external output devices/registers
(Y/YW).
The register numbers of the external input and output registers are consecutive. Thus
one register number can be assigned for either input or output.

As for the T1-16S basic unit, I/O allocation is fixed as follows.

Inputs:

8 points (X000 - X007)

T1-16S

Outputs: 8 points (Y020 - Y027)

X000 --- X007 Y020 ---- Y027

Any operations for the I/O allocation are not required if only the T1 -16S basic unit is
used.
However, if the I/O modules are used with the T1-16S, the I/O allocation operation is
necessary. Refer to the separate manual "T1-16S User's Manual - I/O Modules -".
