Hello mahdy; The first thing to know is the type of RTD you will be connecting to your input module: 2-wire, 3-wire, 4-wire? The screenshot below shows ow you can connect each type. Then you have to set the correct parameters on the module, and how to locate the correct address for the channel you are connecting to. The manual for the temperature module will help you there: https://support.industry.siemens.com/cs/ww/en/view/59753600/104143940747 Once you hve wired and connected to the module correctly, you should be able to read in a value at the selected address, using peripheral addressing: if the channel is set at %IW256, the value shuld be read at %IW256:P. hen comes the scaling. RTD teperature values that you will see at the analog address are multiples of 10 or 100 (depending if you set parameters at 2-decimal or 3-decimal values). so divide by 10 (0or 100) ro get the correct temperature reading. Hope this helps, Daniel Chartier |
