CH1 Wave output current digital value monitor
Wave
This area stores the currently output digital value for each channel.
The stored value depends on the wave output status.
Wave output status
*2
During wave output stop
During wave output
Wave output pause
During wave output step action
*1 The stored values shown are for when 'CH1 D/A conversion enable/disable setting' (Un\G500) is D/A conversion enable (0) and 'CH1
Output enable/disable flag' (Y1) is on. For the analog output in the other status, refer to the following.
Page 23 Analog Output HOLD/CLEAR Function
*2 When an external power supply disconnection or a disconnection is detected, 0 is stored regardless of the setting in 'CH1 Output setting
during wave output stop' (Un\G524).
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Wave output current digital value monitor
■Resetting the stored value
When 'Operating condition setting request' (Y9) is turned on and off, the stored value is reset.
CH1 Wave output digital value outside the range address monitor
Wave
When a digital value, registered as wave data, is outside the setting range, this area stores the corresponding buffer memory
address in 32-bit signed binary for each channel at the time of the value being output.
When the multiple wave data with the digital value out of the setting range are detected, only the buffer memory address of
the wave data detected first is stored.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Wave output digital value outside the range address monitor
■Update of the stored value
When the first detection of the digital value out of the range 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.

Stored value
The digital value of the output set in 'CH1 Output setting during wave output stop' (Un\G524) is stored.
■When set to 0V/0mA (0) or Offset value (1):
0 is stored.
■When set to Output value during wave output stop (2):
The setting value of 'CH1 Output value during wave output stop' (Un\G525) is stored.
The digital value stored in the buffer memory address indicated by 'CH1 Wave output current address monitor'
(Un\G436, Un\G437) is stored.
The stored value depends on the setting of the analog output HOLD/CLEAR function.
■When set to HOLD:
The digital value stored in the buffer memory address indicated by 'CH1 Wave output current address monitor'
(Un\G436, Un\G437) is stored.
■When set to CLEAR:
0 is stored.
The digital value stored in the buffer memory address indicated by 'CH1 Wave output current address monitor'
(Un\G436, Un\G437) is stored.
