Easily change programs using Memory Cards.
Compact flash cards are used, enabling the Memory Cards to be shipped or
mailed for speedy action even with offshore sites.
Handle as Windows Files from a Personal Computer.
User programs, parameters, I/O memory, names (including I/O
comments), and rung comments can be handled as files, enabling
standardization of programs and initial setting data for each
system.
Backup is Simple.
Backup data for the entire PLC, including DeviceNet Units, Serial
Communications Units, and other CPU Bus Units can be saved or
read to a Memory Card. As a result, the same operation as that
using ROM can be achieved using a Memory Card.
Device Manufacturer
Create Files with CX-Programmer.
CJ1
The required files can be attached to email, using
AUTOEXEC.OBJ for the user program file and
ATEXECDM.IOM for the data memory file.
Email
Remote End User
The files are received and copied to a
Memory Card using Windows Explorer or
other program. (CX-Programmer is not
required.)
Onsite, the Memory Card is set in the CJ1-
series CPU Unit and the power supply is
turned ON. The files are automatically read
and operation starts with the new program.

PLC Operation Can Be Switched by Changing
the Memory Card.
When the power is turned ON, the file in the Memory Card can be
automatically transferred to the CPU Unit. As a result, the same
operation as that using ROM can be achieved using a Memory
Card.

CJ1
The Memory Card contains a compact flash card enabling programs to be written without a
PLC. A PC card slot, available on many notebook computers, can be used instead of a
Programming Device.

Advantages in Using Windows Files
Data can be saved on the Memory
Card in CSV or text format for reading
from Microsoft Excel, other
spreadsheet software, or other
programs.
FILE READ and FILE WRITE
instructions can be used during
program execution to transfer I/O
memory data from the CPU Unit to
files in a Memory Card or in EM file
memory. This function enables data,
such as trend data and quality data,
to be saved to a Memory Card during
operation.
