3: The memory capacity of the Q12HCPU or Q25HCPU whose first five digits of serial No. are "02091" or earlier is 64K bytes.
(Refer to Section 2.3 for the way to confirm the serial No.)
4:The CPU shared memory is not latched. The CPU shared memory is cleared when the power is turned on to the PLC or when the CPU
module is reset.
5:The memory capacity of the Q02HCPU or Q06HCPU whose first five digits of serial No. are "04011" or earlier is 64K bytes.
