Data logging function
The following is the list of special relay areas relating to the data logging function.
No. Name Data stored Details Set by (setting
timing)
SM1200 Auto logging setting file and
registration status
Off: Mismatch
On: Matching
• This relay is on when the auto logging setting executed
(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.
S (Status change)
SM1201 SD memory card setting file in
use flag
Off: Not used
On: In use
• This relay switches to on when the data logging
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.
S (Status change)
SM1202 Data memory setting file in
use flag
Off: Not used
On: In use
• This relay switches to on when the data logging
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.
S (Status change)
SM1210 Data logging setting No.1
Data logging preparation
Off: Not prepared
On: Prepared
• This relay switches to on when the data logging
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.
S (Initial)
SM1211 Data logging setting No.1
Data logging start
Off: Suspended/waiting for
start
On: Start
• This relay switches to on when the data logging starts.
The relay turns off when the data logging is in suspend/
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.
S (Status change)
SM1212 Data logging setting No.1
Data logging collection
Off: Not in progress
On: In progress
This relay switches to on when the data logging starts data
collection.
S (Status change)
SM1213 Data logging setting No.1
Data logging end
Off: Not completed
On: Completed
This relay switches to on when the data logging is
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.
S (Status change)
SM1214 Data logging setting No.1
Data logging trigger
OffOn: Triggered The system switches this relay to on when the specified
trigger condition is satisfied.
S (Status change)
SM1215 Data logging setting No.1
After data logging trigger
Off: Not post triggering
On: Post triggering
• This relay switches to on once data logging 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.
