3.4.2 D/A conversion enable/disable setting (Un\G0)
(1) Set whether D/A conversion is enabled or disabled for each channel.
(2) To validate the settings, on/off of Operating condition setting request (Y9) is required.
(Refer to Section 3.3.2.)
(3) By default, all channels are set to D/A conversion disabled.
Design the system so that D/A conversion enable/disable setting (Un\G0)
changes to "Enable" after the external power (Refer to Section 4.3) is supplied.
Analog output may not be performed properly if the external power is not at the
specified voltage.
3.4.3 CH [ ] Digital value (Un\G1 to Un\G6)
(1) This area is used to write digital values from the programmable controller CPU as 16-
bit signed binary code.
(2) If a value outside the settable range is written, the upper or lower limit value of the
range is used for D/A conversion. (Refer to Table3.7.)
Also, if this happens, a check code and an error code will be stored in the CH Set
value check code (Un\G11 to Un\G16) and Error code (Un\G19) respectively.
