POINT
• The reserved areas in the above table and areas not mentioned in the
table are for system use, not for users. If written by a user, the functions
of the QD63P6 are not ensured.
• All data in the buffer memory of the QD63P6 are initialized when the
programmable controller CPU is powered ON or reset. To save
necessary data, use the FROM/DFRO/TO/DTO instructions in the
sequence program or make setting with the utility package for writing/
reading the buffer memory data.
