(10)Conversion from A series to Q or L series
The special relay (M9000 to M9255) for ACPU corresponds to the special relay (SM1000 to SM1255) for QCPU
or LCPU after the A to Q/L conversion. (Note that the Basic model QCPU and Redundant CPU do not support the
A to Q/L conversion.) All bits in this area of the special relay are turned on or off by system (cannot be turned on
or off by user using a program). To turn on or off the bit by user, correct the program using the special relay for
QCPU or LCPU. The special relay (M9084, M9200 to M9255), however, includes the areas that can be turned on
or off by user. For those areas, the bit can be turned on or off by user in the converted special relay (SM1084,
SM1200 to SM1255) as well. For details on the special relay for ACPU, refer to the following.

Meaning Explanation
This relay turns on if an error occurs at
the execution of backup of the CPU
module. This relay turns off at the start of
backup.
This relay turns on if an error occurs at
the execution of restoration of the CPU
module. This relay turns off at the start of
backup.
This relay specifies the operation of
backup when the number of backup data
reaches the upper limit. (Valid only when
bit5 of SD944 is on)
OFF: After deleting the oldest date stamp
folder, the backup is continued.
ON: The backup is not continued if the
upper limit of the number of backup data
is exceeded. (In this case, the backup is
completed with an error.)
This relay turns on when the retry of the
automatic backup is failed even after the
executed/Retry specified number of retries are
being executed attempted, and turns off at the start of the
automatic backup. (This relay does not
turn off when SM1926 is on.)
This relay turns on if an error occurs
during the execution of data logging. This
relay turns off when the data logging is
restarted by turning on SM1938 (Data
logging restart flag at error stop) or is
started or stopped by using the CPU
Module Logging Configuration Tool.
