(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
Settable value by PLC (AD value) Output signal range (a to b)
Voltage [V] Current [mA]
Decimal number
0 to 10 1 to 5 0 to 5 0 to 20 4 to 20
Scale upper limit -32766 to 32767 10 5 5 20 20
Scale lower limit -32767 to 32766 0 1 0 0 4
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.
