REPLACING THE CPU MODULE
(2) Replacement example
The following shows an example of I/O assignment when A0J2HCPU + system including extension
base unit is replaced with the Q series.
Replace with Q00UCPU in the case that A0J2HCPU is used with a system including extension base
unit. Replacement with Q00UJCPU is possible when the I/O number is X/Y00 to X/YFF (256 points) or
less.
