Chapter 6 Sequence Program Used for Positioning Control
6.2 List of devices used
In the sequence programs using QD77MS4 shown in this chapter and subsequent, the
application of the devices used are as follows.
The I/O numbers for Simple Motion module indicate those when the head I/O number
is set to "0H".
If it is set to other than "0H", change the I/O number according to setting of head I/O
number.
In addition, change the external inputs, external outputs, internal relays, data resisters,
and timers according to the system used.
