There are 3 kinds of files that are transferred automatically at startup when
the automatic transfer at startup function is being used.
• AUTOEXEC.IOM or REPLACE.IOM: DM words allocated to Special I/O
Units and Inner Boards.
The contents of this file are transferred to the DM Area beginning at
D20000 when power is turned ON.
• ATEXECDM.IOM or REPLCDM.IOM: General-purpose DM words
The contents of this file are transferred to the DM Area beginning at
D00000 when power is turned ON.
• ATEXECE @ .IOM or REPLCE @ .IOM: General-purpose EM words
The contents of this file are transferred to the EM Area beginning at
E @ _00000 when power is turned ON.
When creating the data files listed above, always specify the first address
shown above (D20000, D00000, or E@_00000) and make sure that the size of
the file does not exceed the capacity of the specified data area.
All of the data in each file will always be transferred starting at the specified
first address (D20000, D00000, or E@_00000).
1. When creating the AUTOEXEC.IOM, ATEXECDM.IOM, and ATEX-
ECE@.IOM files or the REPLACE.IOM, REPLCDM.IOM, or RE-
PLCE@.IOM files from a Programming Device (Programming Console or
CX-Programmer), always specify the proper first address (D20000,
D00000, or E@_00000) and make sure that the size of the file does not ex-
ceed the capacity of the DM Area or specified EM bank. The contents of
the file will always be transferr3ed starting at the proper first address
(D20000, D00000, or E@_00000) even if another starting word is speci-
fied, which could result in the wrong data overwriting the contents of that
part of the DM Area or EM bank. Furthermore, if the capacity of the DM
Area or EM bank is exceeded (as is possible when making settings from
