Explanation
This register stores the usage status of the drives 3 and 4 in the
following bit pattern.
to b5 b4 to b0
b15

This register stores the usage status of the drives 3 and 4 in the
following bit pattern. (Each bit is on while the corresponding
drive is being used.)
b0 : Boot operation (QBT) b8 : Not used
b1 : Parameters (QPA) b9 : CPU fault history (QFD)
b2 : Device comments (QCD) b10 : SFC trace (QTS)
b3 : Device initial value (QDI) b11 : Local device (QDL)
b4 : File register (QDR) b12 : Not used
b5 : Sampling trace (QTD) b13 : Not used
b6 : Not used b14 : Not used
b7 : Not used b15 : Not used
This register stores the usage status of the drives 3 and 4 in the
following bit pattern. (Each bit is on while the corresponding
drive is being used.)
b0 : Not used b8 : Module error log
b1 : Parameters (QPA) b9 : Not used
b2 : Device comments (QCD) b10 : Not used
b3 : Device initial value (QDI) *1 b11 : Local device (QDL)
b4 : File register (QDR) b12 : Not used
b5 : Sampling trace (QTD) b13 : Not used
b6 : Not used b14 : Not used
b7 : Not used b15 : Not used
*1 This bit turns on when the writing of initial device values is
started and turns off at the completion.
*2 This bit can be used when the first five digits of the serial No.
is "11043" or later.

*1 This bit turns on when the writing of initial device values is
started and turns off at the completion.
*2 This bit turns on when data logging setting is registered and
turns off at the completion or stop of data logging.
