Linear Scaling

Is there some way implementing Linear Scaling (Shown below) on Raw values received by PI OPC Interface? I understand we can make use of PIPE but I am looking to do it at interface level

 

((MaxEU-MinEU)/(MaxRaw - MinRaw)) * (RawPV - MinRaw) + MinEu

 

Where

MaxEU = Maximum of Scaled Value

MinEU= = Minimum of Scaled Value

MaxRaw = Maximum Raw Value

MinRaw = Minimum Raw Value

RawPV = Raw Process Values that needs scaling
