File Memory Section 5-1
There are two ways to transfer files automatically at Startup: Transferring with
a parameter area file and transferring without a parameter area file.
Files Used When Transferring with the Parameter File
Type

Extension Description Explanation File
Program
File
AUTOEXEC .OBJ User program • Contains the programs in the CPU
Unit's cyclic and interrupt tasks.
• The file does not have to be on the
Memory Card even when automatic
transfer at startup is specified.
• Transfer will not be possible unless the
Memory Card also contains a parame-
ter area file (AUTOEXEC.STD).
Required
Parameter
Area File
AUTOEXEC .STD PLC Setup, registered
I/O table, routing tables,
CPU Bus Unit settings,
etc.
• Contains the CPU Unit's internal
Parameter Area data.
• The file must be on the Memory Card
when automatic transfer at startup is
specified.
• The user does not have to distinguish
parameter data in the file by type.
• Initial setting data will automatically be
stored at specific locations in the CPU
Unit at startup
• The parameter area file will not be
transferred if the Memory Card contains
a program file called REPLACE.OBJ.
Required
Data File AUTOEXEC .IOM I/O memory data
(Contains the specified
number of words of data
beginning at D20000.)
• Store DM data beginning at D20000 in
a file named AUTOEXEC.IOM.
• At startup, all of the data in the file will
be transferred to the DM Area begin-
ning at D20000.
• This file does not have to be on the
Memory Card when the automatic
transfer at startup function is being
used.

ATEXECDM .IOM
I/O memory data
(Contains the specified
number of words of data
beginning at D00000.)
• Store DM data beginning at D00000 in
a file named ATEXECDM.IOM.
• At startup, all of the data in the file will
be transferred to the DM Area begin-
ning at D00000.
• This file does not have to be on the
Memory Card when the automatic
transfer at startup function is being
used.
Note The data in this file has higher pri-
ority if it overlaps the DM data
contained in AUTOEXEC.IOM.
---
ATEXECE@ .IOM
EM Area data (bank @)
(Contains the specified
number of words of data
beginning at
E@_00000.)
• Store data for EM bank @ beginning at
E@_00000 in a file named ATEX-
ECE@.IOM. The maximum bank num-
ber depends upon the model of CPU
Unit being used.
• At startup, all of the data in the file will
be transferred to EM bank @ beginning
at E@_00000.
• This file does not have to be on the
Memory Card when the automatic
transfer at startup function is being
used.
