Good Afternoon, I've previously used a logo with just digital inputs, so to learn some more I've just got myself a 12/24v logo with a AM2 PT100 module. I've having trouble with getting the PT100 sensor to work. I've the module conneccted and it appears to be working 'green LED'. I've wired the sensor to the M1+ and M1- with a jumper between M1+ and IC1. In the logocomfort v5 I'm making the input AI3 because i've A1 & A2 on the main controller. It works in the simulation, but when upload it and do an online test nothing happens. Any ideas why it's not working??? Many thanks in advance, Skip AttachmentSimple pt100.zip (618 Downloads) |

Hi Skip, look at my example zu view, what your parameters are doing about your sensor inputs. Are the Module and the sensor not wrong, then you have only an output signal "1", ifthe temperature "T" is equal or bigger than 0.5 °C and smaler than 3.0 °C !!! Additional i think you should look at my answers at AM2 PT100 °C precision to find a better scaling of the PT100 inputs to get a full correkt value....

Thank you very much Betel. I've the PT100 sensor reading now and I saw the information of the precision. Thanks again, Skip |
