I/O number
assignment
(When I/O assignment is
not performed)
(1) Assign I/O numbers to the A1SJHCPU first, then to the extension base unit.
(2) Assign I/O numbers as if both the A1SJHCPU and the extension base unit have 8 slots each.A1SJHCPU
has 0 to 4 slots, and 5 to 7 are empty slots.Thus, the empty slots occupies 16 points 3=48 points.
(3) 16 points are assigned to an empty slot.
(4) When an extension base unit for A N or A A is used, be sure to set to a single extension level. If it is set
to the number of skipped stages, 16 points/slot are assigned to all of skipped stages 8 slots, and thus it
does not work.
(5) Items (2) to (3) can be changed by the I/O assignment.(Refer to the ACPU/QCPU-A (A Mode) Programming
Manual (Fundamentals) for details.)
