Averaging
Filtering
To use the scaling function for each input point do the following:
1.
2.
The averaging function can be used to perform averaging of many samples
of data prior to reporting the value to the PLC. This function is useful for
reducing or eliminating noise commonly found in analog input signals. When
averaging is enabled for a particular input point, the module takes the
requested number of input samples for that input point and computes an
average before reporting data to the PLC. The average is the algebraic sum
of all of the conversions for the user-specified count divided by the sample
count value. These values are then discarded and new samples are taken for
the next average computation.
To use this function for each input point do the following:
1.
2.
The filtering function is used to filter samples of data prior to reporting the
value to the PLC. The filtering option is similar in function to the averaging
function. While the averaging function is based on a quantity of counts to
reach the data, the filtering function is based on a time. The filtering function
is useful for eliminating aberrations in the data due to noise or stray induced
signals.
To use this function for each input point do the following:
