Save or read I/O memory data, user programs, and PLC Setup data as files.
Use ROM operation from a Memory Card when at PLC startup.
Log a specified range of I/O memory data in CSV or TXT format using instructions in the user program or Smart FBs (function blocks).
Edit CSV/TXT data logged on a Memory Card on a personal computer using a Memory Card Adaptor.
Use instructions in the user program or Smart FBs to rename, create, or delete directories or files in the Memory Card, to format files, or to
perform other operations.

Note:
Refer to the operation manual for the CS/CJ-series PLCs and NSJ Controller for details on files that can be stored.
Precautions
Confirm the following items before using a Memory Card. Refer to the
CS/CJ/NSJ Series Programmable Controller Programming Manual
(W394)
for details.
Format
The Memory Cards are already formatted when shipped; there is no need to format them again after purchase. To format a Memory Card that
has been used, always format it in the CPU Unit using the CX-Programmer or a Programming Console. You will not be able to use a Memory
Card in the CPU Unit if you format it on a personal computer of in an SPU Unit.
Write Life
Flash memory can be written only a limited number of times. The guaranteed limit for writing to a Memory Card is set at 100,000 writes. That
means if you write to a Memory Card continuously once every 10 minutes, you will exceed 100,000 writes in two years.
Minimum File Size
If many small files, such as ones containing only a few words of DM Area data, are stored on a Memory Card, the Memory Card will become
full sooner than expected. For example, for a Memory Card with an allocation unit size set to 2,048 bytes, a single file will always use 2,048
bytes of space on the Memory Card no matter how little data it contains.
Precautions during Memory Card Access
The BUSY indicator on the CPU Unit will light when the Memory Card is being accessed.
1. Never turn OFF the power to the PLC while the BUSY indicator is lit.
2. Never remove the Memory Card while the BUSY indicator is lit.Before removing a Memory Card, press the button to stop power supply to
the Memory Card and wait for the BUSY indicator to go out. It may become impossible to use the Memory Card if either the power is turned
OFF or the Memory Card is removed while the Memory Card is being accessed.
3. Several seconds are sometimes required for the CPU Unit to detect the Memory Card after the the Memory Card is inserted. The time
required will depend on the cycle time of the PLC, the Memory Card capacity, the number of files on the Memory Card, and other factors.
When accessing a Memory Card, use the Memory Card Detected Flag (A34315) in a NO input condition for the instruction accessing the
Memory Card. Refer to the
CS/CJ/NSJ Series Programmable Controller Programming Manual
(W394) for a programming example.
Precaution when Inserting a Memory Card
The direction the Memory Card must face when it is inserted depends on the model of CPU Unit that is used. With a CS-series CPU Unit, the
label on the Memory Card must face to the right. If a Memory Card is forced into the slot when it is facing the wrong direction, the CPU Unit or
Memory Card may be damaged and fail to operate properly.
