Table of I/O signals

This section describes the I/O signals for the DN91 PLC CPU.
Table 3.3 shows the table of DN91 I/O signals.
The letter "n" in the table represents the leading I/O number of DN91. It is determin-ed by the
position installed and the unit installed before DN91.
<Example> If the DN91 head I/O number is "X/Y30"
Xn0 to X(n+1)F
Yn0 to Y(n+1)F
DN91 → → PLC CPU
