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 un it, I/O allocation is fixed as follows.
Inputs: 8 points (X000 - X007)
T1-16S Outputs: 8 points (Y020 - Y027)
X000 --- X007 Y020---- Y02 7
Any operations for the I/O allocation are not required if only the T1-16S basic un it 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 -".
