Manipulating Files Section 5-2
Note 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.)
3. It is possible to create the AUTOEXEC.IOM, ATEXECDM.IOM, and ATEX-
ECE@.IOM files from a Programming Device (Programming Console or
CX-Programmer), with starting addresses other than D20000, D00000,
and E@_00000 respectively. The data will be written beginning with the
correct starting address anyway, but do not specify other starting address-
es.
4. If DIP switch pin 7 is turned ON and pin 8 is turned OFF to use the simple
backup function, the simple backup function will take precedence even if
pin 2 is also ON. In this case, the BACKUP@@ files will be transferred to
the CPU Unit but the automatic transfer at startup files will not be trans-
ferred. (Not supported by CS-series CS1 CPU Units that are pre-EV1.)
5. The automatic transfer at startup function can be used together with the
program replacement function. The Replacement Start Bit (A65015) can
be turned ON from program that is automatically transferred at startup to
replace it with another program.
File File name At startup Required for
automatic transfer
Program File AUTOEXEC.OBJ The contents of this file are automatically transferred and
overwrite the entire user program including CPU Unit task
attributes.
Required on Memory
Card.
Data File AUTOEXEC.IOM 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.)
Not required on
Memory Card.
ATEXECDM.IOM 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.)
ATEXECE@.IOM 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)
Parameter Area
File
AUTOEXEC.STD The contents of this file are automatically transferred and
overwrite all initial settings data in the CPU Unit.
Required on Memory
Card.
