7.3 Handling the Memory Card 

(1)   Formatting of memory card 

Any SRAM or ATA card must have been formatted to use on the High 

Performance model QCPU. 

Since the SRAM or ATA card purchased is not yet formatted, format it using GX 

Developer before use. 

(The Flash card need not be formatted.) 

For the formatting procedure, refer to the Operating Manual of the GX Developer. 

 

(2)   Installation of SRAM card battery 

A power interrupt hold-on battery is furnished with the SRAM card you 

purchased. 

Before using the SRAM card, install the battery. 

 

 

POINTS 

 

Even if the battery is installed on the CPU module, if a battery is not installed on the 

SRAM card, the memory of the SRAM card will not be backed up. Ensure to install 

the battery on the SRAM card. 

Also, if the battery is installed on the SRAM card but the CPU module has no 

battery, the program memory, standard RAM and latch devices of the CPU module 

are not backed up. Similarly ensure to install the battery on the CPU module. 

 

(3)   Kind of file which can be stored on memory card 

Please refer to the High Performance model QCPU (Q mode) User's Manual 

(Function Explanation, Program Fundamentals) of section 6.1 for the kind of the 

file which can be stored on each memory card.
