7.2 List of devices used
In "Section 7.4 Positioning control program examples", the used devices are assigned
as indicated in the following table.
The I/O numbers for QD70 indicate those when QD70 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 QD70 was installed.
In addition, change the external inputs, internal relays and data resisters, according to
the system used.
