already executed
Data logging function
Auto logging
Data logging function (when the
storage location is the function
memory)
Data logging file transfer (when
the storage location is the function

*1 The data logging function is being executed in the following states where the data logging status remains intact or when the save status
is "Saving".
RUN waiting (no collection)
Condition waiting (no collection)
Start waiting (no collection)
Pause
Collecting
Trigger waiting (Collecting before trigger)
Collecting after trigger
In the states other than the above, although the functions can be executed, the registration of the data logging setting executed first is
canceled when the data logging function or another function is executed.
*2 The data logging function is not included here.

Behavior
If the condition "Total capacity that is set in the internal buffer capacity setting +
Internal buffer capacity that is set in other than the internal buffer capacity setting >
3072K bytes" is satisfied, attempting to start the subsequent function results in an
error. The data logging continues to function normally.
If the internal buffer capacity setting is changed to execute the subsequent function,
attempting to start the subsequent function results in an error. The data logging
continues to function normally.
• Another data logging cannot be executed during the execution of the auto logging.
• Even if data logging is started by using CPU Module Logging Configuration Tool,
another data logging cannot be executed until the SD memory card with the auto
logging setting is removed.
The file batch online change cannot be executed during data logging (when the
storage location is the function memory).
The file batch online change cannot be executed during data logging file transfer
(when the storage location is the function memory).
The CPU module data backup function cannot be executed during data logging file
transfer to the data memory.
The CPU module data restoration function cannot be executed during the data
logging file transfer to the data memory.
