CH1 Wave output warning address monitor
Wave
When a digital value of wave data causes a warning, this area stores the corresponding buffer memory address in 32-bit
signed binary for each channel.
When a warning has occurred in the multiple wave data, only the buffer memory address of the wave data where the warning
occurred first is stored.
■Buffer memory address
The following shows the buffer memory address of this area.

CH Wave output warning address monitor
■Update of the stored value
When the first warning occurs in a wave output status other than "During wave output stop", the stored value is updated.
■Resetting the stored value
To reset the stored value, first change values of wave data that have been outside the setting range so that they fall within the
setting range. After that, turn on and off 'Error clear request' (YF) or 'Operating condition setting request' (Y9) for resetting.
CH1 D/A conversion status monitor
Common
This area stores the D/A conversion status.
D/A conversion status
External power supply OFF
D/A conversion disabled
Analog output disabled
Analog output enabled
*1 Depending on the status of the CPU module and the setting for the analog output HOLD/CLEAR function, the status of analog output
varies. ( Page 23 Analog Output HOLD/CLEAR Function)
*2 In the wave output mode, analog wave data is output according to 'CH1 Wave output status monitor' (Un\G401).
