Default Setting Registration Function

Values in the buffer memory can be changed back to the default.
(1) Condition
Use the default setting registration function in a condition where no digital conversion is performed; set Disable
(1) to Conversion enable/disable setting (Un\G0) for all channels.
Check that digital conversion is disabled by confirming Converting or unused (0) is stored in Conversion
completed flag (Un\G10).
If the default setting registration function is used when digital conversion is in process in even one channel, the
error code (116) is stored in Latest error code (Un\G19), and Error flag (XF) turns on. In this case, the values in
the buffer memory do not change back to the default.
(2) Corresponding buffer memory data and default values
Buffer memory areas that correspond to this function are marked with

Also, the default values are listed in the same table.
