(1) Set whether D/A conversion is enabled or disabled for each channel.
(2) It is necessary to set the operating condition setting request (Y9) to ON/OFF to
validate the D/A conversion enable/disable setting. (See Section 3.3.2.)
(3) By default, all channels are set to D/A conversion disabled.
(4) When Q62DA is used, b2 to b7 (CH3 to CH8) become invalid.

For Q62DA, information for b4 to b15 is fixed at 0.
For Q64DA, information for b4 to b15 is fixed at 0.
(1) This area is used to write digital values for performing D/A conversion from the
PLC CPU as 16-bit signed binary code.
(2) Settings for digital values to be D/A converted when a value outside the valid
digital value setting range is used are listed in Table 3.7.
When a value outside the valid range is written, a check code is stored in the set
value check codes (Un\G11 to Un\G18).
(3) For Q62DA, Un\G3 to Un\G8 (CH3 to CH8) become invalid.
For Q64DA, Un\G5 to Un\G8 (CH5 to CH8) become invalid.
