S7200-226 is equipped with universal analog input module 23 1, and PT 100 thermal resistance sensor is equipped with temperature transmitter (measuring range is -50- 100, output is 4-20mA).
4mA corresponds to minus 50 degrees, and 20mA corresponds to 100 degrees;
4-20mA corresponds to 6400-32000;
It is best to convert the value of AIW into the actual temperature value in PLC program.
This looks more convenient.
