3.4 I/O Signals to the PC CPU
The I/O signals for the master/local module's PC CPU is described.
3.4.1 I/O signal list
The list of I/O signals is described in Table 3.3.
The "n" in the table indicates the master/local module's first I/O number, and it is
determined by the installation position and the module installed before the master/local
module.
<Example> When the master/local module's first I/O number is "X/Y30":
Xn0 to X(n+1)F X30 to X4F
Yn0 to Y(n+1)F Y30 to Y4F
