Description
OFF: Normal
ON: Aggregating
OFF: Aggregation complete
Turns on if the CPU unit is powered off while accessing an SD
memory card.
Description
Turns on when an error occurs in the FP7 MW Unit.
The error code and unit number is stored in the system registers
SD90 to SD95.
Description
Turns on when the logging trace is performed. Other relays in LOGn
turns off while this relay turns on. Storing data in the buffer memory
is executed while this relay turns on.
Turns on when writing files to a SD card becomes enabled after the
logging trace execution relay turned on (buffer logging was enabled).
Turns on after the completion of file writing when stopping the
logging trace is requested or it is automatically stopped.
● Turns on when the buffer logging speed exceeds the writing
speed to an SD memory card in logging operation. Turns on
when the number of data previously stored and the number of
data stored this time increase.
● Turns on at the timing of buffer logging, and turns off at the timing
of buffer logging or the end of scan.
● Turns on when the buffer memory has been exhausted. At that
time, new data cannot be stored.
● The value of the buffer overflow counter SD120 is incremented
(+1). In that case, writing to the SD memory card does not stop.
● Turns off at the end of scan when buffer vacancy occurs while
writing to a SD memory card is performed. The buffer overflow
counter SD120 is cleared to 0.
● After buffer vacancy occurred, data logging is executed at the
timing of logging to the buffer.
