8.11 Shift Function
The initial value of the shifting amount to conversion value is 0.
If the digital output value exceeds the range of -32768 to 32767 as a result of shift addition, the digital output value is fixed to
the lower limit value (-32768) or the upper limit value (32767).
(3) Setting example
When the following settings are used for a channel with input range of -10 to 10V:
• "Shifting amount to conversion value": 20000
The following figure and table show CH1 Digital output value (Un\G11) and CH1 Scaling value (digital operation
value) (Un\G54).
*1 Since the value exceeds the range of -32768 to 32767, it is fixed to 32767 (the upper limit value).
