6 SEQUENCE PROGRAM USED FOR POSITIONING CONTROL
6.2 List of devices used
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.
