5.2 Memories Used for High Performance model QCPU, Process
CPU, and Redundant CPU
5.2.1 Memory composition and storable data
This section describes the memories used for the High Performance model QCPU, Process CPU, and Redundant
CPU and data that can be stored in the memories.
(1) Memory composition
(a) Program memory (
This memory is for storing programs and parameters for CPU module operation.
(b) Standard ROM (
This memory is for storing data such as parameters and programs.
Programs and parameters can be stored without battery backup.
(c) Standard RAM (
This memory is for using file registers, local devices, and sampling trace files without a memory card.
(d) Memory card (
This memory is for expansion of built-in memory in the CPU module.
Three types of memory cards are available: SRAM card, Flash card, and ATA card.
