8.7 Shift Fu
nction
(4) Setting example of when both the scaling function and shift function are used
Ex.
When the following settings are used for a channel with output range of 0 to 5V:
• "CH
Scaling enable/disable setting": "0: Enable"
• "CH
Scaling upper limit value": 9000
• "CH
Scaling lower limit value": 3000
• CH
Shifting set value (RWw6 to RWw9): -25
The digital value is as follows:
Analog output
