Data stored Details
Off: Mismatch • This relay is on when the auto logging setting executed
On: Matching (registered) matches with the content of the configuration
file stored in the target memory. This relay is off when the
setting does not match with the content.
Off: Not used • This relay switches to on when the data logging
On: In use configuration file stored in an SD memory card is being
used. This relay switches to on when one or more data
logging of the settings No.1 to 10 is registered.
• The ON state is maintained even when the data logging
later enters into suspend/waiting for start without
collection/waiting for RUN without collection mode.
However, the relay switches to off when all the data
logging stops.
Off: Not used • This relay switches to on when the data logging
On: In use configuration file stored in the data memory is being
used. This relay switches to on when one or more data
logging of the settings No.1 to 10 is registered.
• The ON state is maintained even when the data logging
later enters into suspend/waiting for start without
collection/waiting for RUN without collection mode.
However, the relay switches to off when all the data
logging stops.
Off: Not prepared • This relay switches to on when the data logging
On: Prepared preparation is completed.
• The ON state is maintained even when the data logging
later enters into suspend/waiting for start without
collection/waiting for RUN without collection mode. This
relay switches to off when the data logging stops.
Off: Suspended/waiting for • This relay switches to on when the data logging starts.
start The relay turns off when the data logging is in suspend/
On: Start waiting for start without collection mode. Associated
special relay, such as Data logging collection, Data
logging end, Data logging trigger, and After data logging
trigger, switches to off simultaneously.
• This relay also switches to off when the CPU module is
moved from RUN to STOP mode and therefore the data
collection is halted.
Off: Not in progress This relay switches to on when the data logging starts data
On: In progress collection.
Off: Not completed This relay switches to on when the data logging is
On: Completed completed. For continuous logging, the corresponding bit
switches to on when writing reaches the maximum number
of storage files and data logging is completed (with "Stop"
set for the operation at the time when the number of save
files exceeds the limit). For trigger logging, the
corresponding bit switches to on when data collection for
the specified number of records has been completed
followed by writing into the SD memory card after the
trigger condition was satisfied. The bit also switches to on
when an error is generated (except for data logging error
caused by online program change) during the data logging
execution.
OffOn: Triggered The system switches this relay to on when the specified
trigger condition is satisfied.
Off: Not post triggering • This relay switches to on once data logging triggering
On: Post triggering occurs. The ON state is maintained even when the data
logging is completed. However, this relay is off when the
data logging is in suspend/waiting for start without
collection/stop mode
• This relay also switches to off when the CPU module is
moved from RUN to STOP mode and therefore the data
collection is halted.
