APR function - help

Hi all...

I want to scale data from analog input which I defined as

Name: _LEVEL

Type: CHANNEL

I defined also next D words

D10000 - ParamControlWordLevel UINT

D10001 - ParamAnalogLowLevel INT

D10003 - ParamOutLowLevel REAL

D10005 - ParamAnalogHighLevel INT

D10007 - ParamOutHighLevel REAL

Scaled variable is MeasureLevel REAL W20

I have set on PLC first cycle ParamControlWord=#0201, use floating point with one linear segment, ParamAnalogLowLevel=#0000, ParamAnalogHighLevel=#4000 (current input).

ParamOutLowLevel and ParamOutHighLevel sets administrator from touch panel.

APR Call parameters are 1. Control word = ParamControlWord 2. Source = _LEVEL 3.Result = MeasureLevel

Is this good configuration?

What if I have something in Source word (etc. #1160), but Result is zero (+0.0).

Best regards,

Milos
