Hello Ahmed; You will find the answer to all your scaling value issues in the S7-300 Module Data manual, in the chapters discussing analog value representation. http://support.automation.siemens.com/WW/view/en/8859629 The attached table is extracted from that manual, and shows that if your RTD is within its normat range, the scaling factor is 10. All you need to do is to take the PIWxxx value from the RTD channel,convert it into a REAL valueand divide it by 10.0 to obtain the temperature reading (with one decimal point). Hope this helps, Daniel Chartier |
