In the sequence programs shown in this chapter and subsequent, the application of the
devices used are as follows.
The I/O numbers for QD75 indicate those when QD75 is mounted in the 0-slot of the
main base.
If it is mounted in the slot other than the 0-slot of the main base, change the I/O
number to that for the position where QD75 was installed.
In addition, change the external inputs, external outputs, internal relays, data resisters,
and timers according to the system used.
