Program Example
• Data Flow (Unit Number 0): Word 2001 (A/D Conversion Value)
→ Word 0200 (Calculation Result)
(1) The negative number portion is added to the conversion value (word 2001).
(2) The binary data is scaled to a range of 0 to 4000.
(3) The scaling results are multiplied by 4400.
(4) The square root is calculated, and the result is output to word 0200.
DM Area Settings
Input signal range: 0 to 10 V / 1 to 5 V / 4 to 20 mA
If the result of the binary-to-BCD conversion is negative, an error will be generated by the ROOT(072) instruc-
tion.
With a signal range of –10 to 10 V, scaling is executed by augmenting the negative portion (–10 V –5%). In this
program example, the value of D00000 is converted to 0898. Refer to Scaling on page 366 for details.
Mean Value Processing
Data is taken for the set number of samplings and the mean value is calculated.
