A40115 ON when an error occurred in memory or there was an error in automatic
transfer from the Memory Card when the power was turned on (automatic
transfer at start-up).
The CPU Unit will stop and the ERR/ALM indicator on the front of the CPU
Unit will light.
Note: A40309 will be turned ON if the error occurred during automatic trans-
fer at startup. (The error cannot be cleared in this case.)
A40309 ON when automatic transfer at start-up has been selected and an error
occurs during automatic transfer (DIP switch pin 2 ON). An error will occur if
there is a transfer error, the specified file does not exist, or the Memory Card
is not installed.
Note: The error can be cleared by turning the power off. (The error cannot
be cleared while the power is on.)
The I/O allocation status depends on the unit versions of the source and des-
tination CPU Units when using a single CJ-series CPU Unit to create parame-
ter files for automatic transfer at startup, save them in the Memory Card, and
then automatically transfer them to another CJ-series CPU Unit at startup.
The changes to I/O allocation status for different unit version combinations is
shown in the following table.

1. When files for automatic transfer at startup (AUTOEXEC.STD) are created
and saved in a Memory Card using user-specified I/O allocations with a
pre-Ver. 2.0 CJ-series CPU Unit, the system will automatically switch to au-
tomatic I/O allocation at startup if the data is automatically transferred from
the Memory Card.
2. When files for automatic transfer at startup (AUTOEXEC.STD) are created
and saved in the Memory Card using a CJ-series CPU Unit with unit ver-
sion 2.0, the I/O allocation status will switch automatically to user-specified
I/O allocations if the data is automatically transferred from the Memory
Card to a CJ-series CPU Unit with unit version 3.0 or later.
