Hello Badreddine; If you are using a SM 1331 RTD module connected to a PT100 sensor, you should be able tp read from -243 to +800 degrees C. https://support.industry.siemens.com/cs/us/en/view/43346925/19664422923 What value do you read ehen you attempt to input a negative temperature value? Hope this helps, Daniel Chartier |

hi Badreddine0077, what do you get in the input-word? How is the module parametrized? PT100 Standard has a range from -200° to 850°C as it is described in the manual Get sure that the variable you are using is an Integer(INT) hope this helps, regards, |
