Hello everybody I have a doubt, replace some temperature controllers and flow of the West brand, in their place I'm using a PLC S7-300 analog inputs and outputs, the detail that it seems that the process was mei out, for example the temperature process values ​​are high despite the PID of the PLC is controlling the Temperature Range this high, but my control valve 3-way thermal oil is completely closed! Sera that the controller was giving full scale and I do not see the correct Temperature Range PLC and now is giving to visualize what actually happens.
