5.6 Examples of the Calculation of the Measured Values
from the Process Values
The format of signed measured values (Int32) is the two's complement.
In general, the following formula applies to the calculation of the measured
values from the process values:
The scaling factor PI is defined for each measured value in the section
"Measured Value Collections." Examples of the calculation follow:
