Appendix 4 List of Special Relay Areas
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) CPU
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.

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.

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.

SM1203 Data logging file transfer
stop request
OffOn:Stop request exists
OnOff:Transfer stopped
• This relay stops the data logging file
transfer according to the value specified
in SD1203 when this relay is changed
from off to on.
• This relay turns off when the data logging
file transfer is stopped.

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.

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.

Data logging collection
Off: Not in progress
On: In progress
This relay switches to on when the data
logging starts data collection.
