5.2.5 Memory card
(1) Definition
This memory is for expansion of a memory in the CPU module.
The following three types are available:
• SRAM card
• Flash card
•ATA card
(a) SRAM card
File registers in the SRAM card can be written or read by the sequence program.
The SRAM card is used when:
• the number of file register points is greater than the standard RAM capacity,
• the sampling trace function is used, or ( Section 6.14)
• 17 or more error history data are saved. ( Section 6.18.2)
When storing file registers to the SRAM card, the file registers can be written or read by the sequence program
up to 1018K points.
(b) Flash card
Write data by GX Developer and read it by the sequence program. (Data can be read only by the sequence
program.)
Use the Flash card when data are not changed.
File registers can be stored up to 1018K points.
(c) ATA card
This card is used for programmable controller user data (general-purpose data).
With the file access instruction (such as the SP. FWRITE instruction) in the sequence program, access the
programmable controller user data in the ATA card in CSV format/binary format.
