Precautions
With 'CH1 Output enable/disable flag' (Un\G70, b1) enabled, any CPU module change from RUN to STOP changes this flag
to Disable.
At this time, if the analog output HOLD/CLEAR function setting is the previous value, the analog output will hold the last output
value. If the analog output HOLD/CLEAR function setting is the setting value, the analog output will be the HOLD setting
value.
When the CPU module is set to RUN again, 'CH1 Output enable/disable flag' (Un\G70, b1) remains disabled. However, the
analog output will not be the offset value, and output of the previous value or HOLD setting value will continue.
When 'CH1 Output enable/disable flag' (Un\G70, b1) is enabled, output of the value D/A-converted from the digital value is
restarted.

*1 When the CPU module changes from RUN to STOP or a disconnection has occurred, the wave output status changes to the wave
output stop.
*2 When a watchdog timer error occurs, 'Module READY' (Un\G69, b0) turns off and the RUN LED of the analog output module turns off.
*3 Output as per the setting of 'CH1 Output setting during wave output stop' (Un\G524).
*4 Also when the CPU module changes from STOP to RUN, the value is output according to the analog output HOLD/CLEAR function
setting.
*5 When the external supply power shuts off or a disconnection is detected and then it is restored, the output will be as follows.
If the CPU module is RUN: Output that was selected in Wave output stopped selection.
If the analog output HOLD/CLEAR function is being used for output because the CPU module has changed from RUN to STOP: Offset
value.
