Hello Romioo; There are 2 possible issues here, since S_ITR (scale integer to real) is a standard scaling function proposed by Siemens. https://support.industry.siemens.com/cs/ww/en/view/27043396 1- the output of the S_ITR function does not provide an expected (in range) value for your program. Have you used a Status Chart to track the output of the S_ITR and check the results? 2- your simulator is not working as you expected, or you are not connected to it properly. What is the simulator you are working with? Siemens never did propose a simulator for the S7-200, and none of the ones that I tried from the web ever produced clear results. Can you provide screenshots on how your simulator reads the output of your S_ITR? Hope this helps, Daniel Chartier |
