This section explains the input/output signals that the QJ71DN91 sends to or receives
from a programmable controller CPU.
The I/O signal assignments shown are based on the case where the start I/O No. of
the QJ71DN91 is "0000" (mounted to slot 0 of a main base unit).
Device X denotes an input signal from the QJ71DN91 to the programmable controller
CPU.
Device Y denotes an output signal from the programmable controller CPU to the
QJ71DN91.
Table 3.5 lists the I/O signals used for the programmable controller CPU.
