3.4.21 Mode switching setting (buffer memory addresses 158, 159: Un\G158, Un\G159) 
(1)      Set the values of the mode desired to be switched to. 
 
(2)      After setting the values, turning the operating condition setting request (Y9) from 
OFF to ON switches to that mode. 
 
(3)      When mode switching is performed, this area is cleared to zero and the 
operating condition setting completed flag (X9) turns OFF. 
After confirming that the operating condition setting completed flag (X9) has 
turned OFF, turn OFF the operating condition setting request (Y9). 
 
Mode to be switched to 
Set values 
Buffer memory address 158  Buffer memory address 159 
Normal mode  0964H 4144H 
Offset/gain setting mode  4144H 0964H 
 
POINT 
 
If the values written are other than the above, mode switching is not performed and 
only the operating condition is changed. 
 
3.4.22 Pass data classification setting (buffer memory addresses 200: Un\G200)   
(Q64AD-GH only) 
(1)      Areas used to restore the user range settings offset/gain values when online 
module change is made. 
Refer to chapter 7 for details of online module change. 
 
(2)      Specify whether the offset/gain values to be saved/restored are voltages or 
currents when saving/restoring the offset/gain values of the user range setting.
