Memory card
use
conditions
This register stores the usage status of a memory card in the
following bit pattern. (Each bit is on while the memory card is
being used.)
*1 This bit turns on at boot start and turns off at the
completion.
*2 This bit turns on when the writing of initial device values
is started and turns off at the completion.
*3 This bit can be used when the first five digits of the serial
No. is "10102" or later.
*4 For the QnUDVCPU, this bit is fixed at OFF.
*5 This bit is used only for the QnUDVCPU. This bit turns
on when data logging setting is registered and turns off
at the completion or stop of data logging.

following bit pattern. (Each bit is on while the memory card is
being used.)
*1 This bit turns on at boot start and turns off at the
completion.
*2 This bit turns on when the writing of initial device values
is started and turns off at the completion.
*3 This bit turns on when data logging setting is registered
and turns off at the completion or stop of data logging.
*4 This bit turns on while;
• The batch save function or the batch load function is being
executed.
• The iQ Sensor Solution data backup or restoration function
is being executed.
*5 This bit turns on while checking the predefined protocol
setting data and turns off at the completion.
