Shifting Input Values

 Shifting Inputs
You can set the Process Value Slope Coefficient and Process Value Input Shift parameters to
compensate the PV.
Process Value Input Shift
Process Value Slope Coefficient
• Calculating the Process Value Slope Coefficient and Process Value Input Shift
In the following equation, PVi is the input to the calculation, PVo is the result, INRT is the process
value slope coefficient, and INS is the process value input shift: PVo = (PVi × INRT) + INS
 Moving Average
• The moving average operation reduces sudden changes in the input due to noise and other
factors, and can be enabled separately for each input.
• The Moving Average Count parameter is used for the moving average. It can be set to OFF, 2, 4,
8, 16, or 32.
• The default is OFF (disabled).*

 Input Digital Filter
You can use the input digital filter to help remove the noise component from input signals.
If you set the Input Digital Filter parameter to any value other than 0.0, the filter works as a robust
filter to reduce high-frequency noise.
