(3) Scaled data format
Function to set any value between "-32767 to 32767" as the AD value for output signal range.
Resolution is determined by specifying the upper and lower scale limit.
Upper limit value of the range - Lower limit value of the range
Resolution =
Upper limit value of the scale - Lower limit value of the scale
Example: when the range is 1 to 5 V
(1)Set the range to 1 to 5 V.
(2)When the upper limit of the scale is set to
5000, and the lower limit of the scale is set
to 1000, the result will be as follows.
1000
･･･
1 V output
2000
･･･
2 V output
3000
･･･
3 V output
4000
･･･
4 V output
5000
･･･
5 V output
(3)The resolution from 1 to 5 V is 1/1000 based
on the calculation.
(5 V - 1 V) / (5000 - 1000) = 1/1000

If the data format is scaled data format, set the Fault Value as follows, regardless of the range setting.
•PLC settable value: 0 to 32767
→
Converted value +0 to +32767
•PLC settable value: 32768 to 65535
→
Converted value -0 to -32767
Example: To set the Fault Value to 4 V when range is 1 to 5 V (analogue output range), scale upper
limit 5000, and scale lower limit 1000, set 4000 to Fault Value by PLC.
