3.4 Buffer Memory
3.4.1 List of buffer memory assignments
The following table indicates the assignment of the QD60P8-G buffer memory. Refer to
Section 3.4.2 for details of the buffer memory areas.
The initial values are set to the buffer memory at power-on or when the programmable
controller CPU is reset. (When power is switched OFF, the setting values in the buffer
memory are not retained.)
The sequence program or programmable controller CPU's auto refresh function,
reads/writes the buffer memory contents.
The settings are reflected on the module by turning ON the operating condition setting
request flag (Y1) after the data have been written to the buffer memory.
