Example 1
The Cscape Scale function, found in the Advanced Math functions, allows for very easy
conversion of the raw input value into a meaningful reading. For example, a pressure
transducer may be specified as a 4-20mA signal to signify a 0-2000 psi pressure reading.
With the analog channel set to the 4..20mA range, the raw analog input value, which is in INT
format ranges from 0 to 4mA to 32000 for 20mA. Use the Scale function to obtain an Integer
pressure reading using the 0-
32000 raw input range and the sensor’s 0 -2000psi output
range.
Example 2:
If readings with fractions are required, the raw Integer input value must first be translated in
REAL, or Floating Point format. The Cscape INT-to-REAL Conversion function may be used to
convert the raw input value from INT to REAL format in an intermediate memory location. The
SCALE function, specified as REAL type, may be used to scale the converted raw value into a
reading that supports digits beyond the decimal place, i.e. 475.25psi.
