9.7.1 File register data storage location

The file register data are stored in the following memories.
• Basic model QCPU:
Standard RAM
• High Performance model QCPU, Process CPU, and Redundant CPU:
Standard RAM, SRAM card, or Flash card

9.7.2 File register size

(1) When using the standard RAM
The table below shows the maximum points of file register data that can be stored in the standard RAM.
Note that, however, if the standard RAM is used for an application other than file registers, available points are
decreased.

Basic model QCPU
High Performance model QCPU
Process CPU
Redundant CPU
*1: Since the standard RAM size varies by CPU module version, the number of available points is different. (
