Jazz and pt 100

Hello,

 

You don't need to use any special function for reading the temperature.

In hardware configuration within the software, select PT1000 for the analog channel on which you have connected your RTD and link an MI to it.

Temperature reading from the sensor is directly stored in this MI.

You can also apply a filter and switch between Celsius and Fahrenait.

 

Temperature range for PT1000 is -50° to 400°C  with a resolution of 0.1°C.

So if your MI reads 254, it will be 25.4°C.

 

Attached is an example for your reference.

The PT1000 value has an implied decimal point. Your set value doesn't. In order to do a compare you need both values to have the same number of implied decimals. The easiest thing to do is to use a set point that also has one implied decimal, but is you want to enter whole numbers only then you need to multiply the entered set value by 10 (and store it in a separate place) before you do the compare.
