Taithan Posts: 3 Rating: (0)	Thanks! Now, I'm intend to write a program with content : " control a VAN_PID ( supply stream for a Tank to boil ), with feedback is Pressure Sensor and Temperature Sensor.Can I use FB58 or FB41 in Standard Fuctions of Step7? What's is the different between them?

FB58 is specific to control temperature: it can accept directly PIW from PT100 or termocoplers, has works zone (for pre heating, or pre cooling), and can find itself the best parameters for Kp Ki Kd.
