(4) Memory card
This memory is used to extend memory in a CPU module. Three types of memory cards are applicable.
• SRAM card
• Flash card
• ATA card
(a) SRAM card
Data can be read from or written to a file register file stored in an SRAM card by sequence programs.
This card is used when:
• the number of file register points is greater than the standard RAM capacity, or
• the sampling trace function is used. (
When storing file registers to the SRAM card, the file registers can be written or read by the sequence program
up to 4086K points.
(b) Flash card
This card is used when changing data is not required. Data are written to the card using a programming tool
and read from the card by sequence programs. (Data cannot be written to the card by sequence programs.) Up
to 2039K points of file register data can be stored.
(c) ATA card
This card is used for PLC user data (general-purpose data).
With the file access instruction (such as the SP. FWRITE instruction) in the sequence program, access the PLC
user data in the ATA card in CSV format/binary format.
(5) SD memory card
This memory stores programs and parameters. To execute programs stored in an SD memory card, perform boot
operation. ( Page 102, Section 2.11) To execute the data logging function, this card must be inserted.
