Range Switching Function

Common
This function allows switching the output range of an analog output for each channel.
Switching the range makes it possible to change the I/O conversion characteristic.
Operation
The set digital value is converted to an analog value within the analog output range of the output range set in "Output range
setting" and the analog value is output.
The digital value used in the D/A conversion varies depending on the operation mode.
• High-speed output mode, normal output mode: 'CH1 Digital value' (Un\G460)
• Wave output mode: Wave data registry area (Un\G10000 to Un\G99999)
• Inter-module synchronization mode: 'CH1 Synchronization digital value' (Un\G9500)
Setting method
Set the output range to be used in "Output range setting".
