3.4.2 D/A conversion enable/disable setting (buffer memory address 0: Un\G0)
(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.

3.4.3 CH digital values (buffer memory addresses 1, 2: Un\G1, Un\G2)
(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, Un\G12).
