7-3 Section Using File Memory
143
The files described in the following table can be read or written by the CPU Unit.
File type File name Extension Contents Description
Data file ******** .IOM Specified ranges of
I/O Memory
•
Contains word (16-bit) data from a starting
word through an end word in one memory
area.
•
The following areas can be used: CIO, HR,
WR, AR, DM, and EM.
Program file ******** .OBJ Complete user
program
•
Contains all the programs for cyclic tasks
and interrupt tasks, as well as task informa-
tion for one CPU Unit.
Parameter area file ******** .STD

Setup data (See
Note 1.)
•
Contains all of the parameter data for one
CPU Unit.
•
There is no need for the user to distinguish
the various types of data contained in the
file.
•
The file can be automatically read to or writ-
ten from the CPU Unit simply by specifying
the extension (.STD)
Files
trans-
ferred at
startup Data files AUTOEXEC .IOM I/O Memory data for
the specified number
of words starting
from D20000
•
There does not necessarily need to be a
data file in the Memory Card when the auto-
matic file transfer function is used at startup.
•
The AUTOEXEC.IOM file always contains
DM Area data starting at D20000.
•
All data in the file will be transferred to
memory starting at D20000 at startup.
Program
files AUTOEXEC .OBJ Complete user
program
•
There must be a program file in the Memory
Card when the automatic file transfer func-
tion is used at startup.
•
Contains all the programs for cyclic tasks
and interrupt tasks, as well as task informa-
tion for one CPU Unit.

•
There must be a parameter file in the
Memory Card when the automatic file trans-
fer function is used at startup.
•
Contains all of the parameter data for one
CPU Unit.
•
There is no need for the user to distinguish
the various types of data contained in the
file.
•
All parameters in the file will be automatical-
ly transferred to specified locations in
memory at startup.

Programmable Controllers Operation Manual (W339).
2. All files transferred automatically at startup must have the name AUTOEX-
EC.
Initializing File Memory
Memory Initialization method
Memory
Cards 1. Insert the Memory Card into the CPU Unit.
2. Initialize the Memory Card from a Programming Device
(Programming Consoles included).
EM File
Memory 1. Specify in the PC Setup the first bank to convert to file memory.
2. Initialize EM File Memory from the CX-Programmer.
