hello dear expert

these are some temperature in my machine which sense the heat by pt100 .

i wonder if u could inform me that how to convert the PIW  quantity to temperature (centigrade)!?

:L    PW 132
:SRW    3
:T    DW   2
:L    KF 3000
:>F
:JC   =M001
:TAK
:L    KF 350
:<F
M001 :=    F    8.1
:***
so when the temperature is around 27 centigrade piw132 shows 2640 and srw 3 shows 4c8 !

i know i should replace it in slope of line formula and also i know that when x0=0 then y0=1024 and also for 20ma x1=266 then y1=2048!

i replace them in slope of line formula but the result is not correct!

so , do u have any idea about?

thank u

ohh. sorry for not mentioning it. its 6es5-928-3ub11

Try this: 

:L    PW132
:SRW    3
:FDG                  // Convert to floating point.
:L    KG+2597656+00
:XG
:L    KG+2660000+03
:-G                   // Result in floating point.
:GFD                  // Convert to fixed point.

hi

according to your response o forum for scaling a pt100 we have to try this :

:L    PW132
:SRW    3
:FDG                  // Convert to floating point.
:L    KG+2597656+00
:XG
:L    KG+2660000+03
:-G                   // Result in floating point.
:GFD                  // Convert to fixed point.

so its a question here that how u can determine the difference between 0-150 and 0-200 degree centigrade transmitter (4-20ma) ?

my cpu is: 

6es5-928-3ub11

would u help me ?
