Automatic Transfer at Startup

Program File AUTOEXEC.OBJ
Parameter Area AUTOEXEC.STD

Data File AUTOEXEC.IOM
ATEXECDM.IOM
ATEXECE@.IOM
Note
Automatic transfer at startup is used to read the user program, parameters,
and I/O memory data from a Memory Card to the CPU Unit when the power is
turned ON.
The following files can be read automatically to CPU Unit memory.
Note This function cannot be used to read EM file memory.
The program file name depends on whether a parameter area file is also
going to be transferred.
Use the following file names.
Program file: AUTOEXEC.OBJ
Parameter area file: AUTOEXEC.STD
Data files: AUTOEXEC.IOM, ATEXECDM.IOM, ATEXECE@.IOM
CPU Unit
I/O memory

Write at startup
data
The contents of this file are automatically transferred and
overwrite the entire user program including CPU Unit task
attributes.
The contents of this file are automatically transferred and
overwrite all initial settings data in the CPU Unit.
DM words allocated to Special I/O Units, CPU Bus Units,
and Inner Boards (CS Series only).
The contents of this file are automatically transferred to
the DM Area beginning at D20000 when power is turned
ON. (See note 1.)
General-purpose DM words
The contents of this file are automatically transferred to
the DM Area beginning at D00000 when power is turned
ON. (Not supported by CS-series CS1 CPU Units that are
pre-EV1) (See note 1.)
General-purpose DM words
The contents of this file are automatically transferred to
the EM Area beginning at E@_00000 when power is
turned ON. (Not supported by CS-series CS1 CPU Units
that are pre-EV1)
1. If the data contained in AUTOEXEC.IOM and ATEXECDM.IOM overlap,
the data in ATEXECDM.IOM will overwrite any overlapping data trans-
ferred from AUTOEXEC.IOM since ATEXECDM.IOM is written later.
2. The program file (AUTOEXEC.OBJ) and parameter file (AUTOEXEC.STD)
must be on the Memory Card. Without these files, automatic transfer will
fail, a memory error will occur, and A40115 (Memory Error Flag: fatal error)
will turn ON. (It is not necessary for the I/O memory file (AUTOEXEC.IOM)
to be present.)
