Power supply module CPU module
(I/O assignment for the AnS series before
replacement)
(1) Setting the start XY address of each slot
(I/O assignment for the Q series after replacement)
After replacement, the start I/O numbers of
the first extension base unit will be "X/Y50".
Q35B
(I/O assignment for the Q series when the start XY
address of each slot is set after replacement)

(2) Setting the number of slots to "8"
(I/O assignment for the Q series when the number
of slots of the base unit is set after replacement)

Setting the number of
slots allows the CPU
module to start the I/O
numbers of the first
extension base unit
from X/Y80.

allows the CPU module
to use the same XY
address used in the AnS
series CPU module.
