This section describes the I/O signal assignment and the applications of each signal.
(1) The Q62HLC uses 16 input points and 16 output points to transfer signals
to/from the programmable controller CPU.
(2) Table 3.7 lists the I/O signals of the Q62HLC.
Input (X) is a signal from the Q62HLC to the programmable controller CPU, and
output (Y) is a signal from the programmable controller CPU to the Q62HLC.
(3) The I/O signals (X, Y) explained in this manual are those for when the Q62HLC
is mounted on the I/O slot 0 of the main base unit.
If the Q62HLC is mounted on a slot other than the I/O slot 0, change the I/O
signals to those of the slot where the module is mounted.
