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 pro-
gram
• Contains all the programs for cyclic tasks
and interrupt tasks, as well as task infor-
mation for one CPU Unit.
Parameter area file
********
.STD
• PLC Setup
• Registered I/O
tables
• Routing tables
• CPU Bus Unit
Setup and other
setup data
• 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
written from the CPU Unit simply by speci-
fying 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
automatic 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 pro-
gram
• There must be a program file in the Mem-
ory Card when the automatic file transfer
function is used at startup.
• Contains all the programs for cyclic tasks
and interrupt tasks, as well as task infor-
mation for one CPU Unit.
Parameter
area file
AUTOEXEC
.STD
• PLC Setup
• Registered I/O
tables
• Routing tables
• CPU Bus Unit
Setup and other
setup data
• There must be a parameter file in the
Memory Card when the automatic file
transfer 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 automati-
cally transferred to specified locations in
memory at startup.
