•Scaled data format
Function to set any value between -32767 to 32767 as the AD value for I/O 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
Upper limit value of the scale
-
Lower limit value of the scale
Example: when the range is 1 to 5 V output
(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
Scale set value (AD value)
Input/Output signal range (a to b)
Note: If the data format is scale conversion format, set the scale upper and lower limit value as follows,
regardless of the range setting.

(Data format: scale conversion format)
Example: To set the Fault Value to 4 V when the range is 1 to 5 V (analogue output range), scale upper
limit 5000, and scale lower limit 1000, set 4000 to Fault Value using the CoE object.
