Hi Kuldeep,

What do you mean by "transformation"?  A linear "transformation" could mean Out = A + B*In which the aCalcout record can certainly do.

Your next sentence suggests you mean curve fitting.  In that case please explain what "transform both ways" means.

Subject: Polynomial Transformation / Curve Fitting in EPICS

 

Hello,

Can anyone please suggest to me any module in EPICS/SynApps which allows for user selectable linear, quadratic and polynomial based transformation. I should be able to transform both ways and recalibrate the curve fitting coefficients in the field.

Thank you in advance.

Regards,

Kuldeep
