See also: Chapter 7.13. CONTROLLERS.
Task:
The task is to configure the controller which will control (via RS-485) the heater in order
to obtain a constant object temperature. Logical channels with a set point value and
temperature from the PT100 sensor are connected to the controller. After pre-analysis of
the sensor type and the transmittance of the object, we set the controller coefficients to the
following values: P=0.3, I=0.5, D=0.02. We do not want the controller to respond to a
deviation lower than 2ºC. On controller's output set 0-20mA range because that is the range
of the converter we use to control the heater in this task.
Solution:
First configure the controller, then connect the Pt100 sensor and Current converter to
the device. An example of this connections in presented in
Fig. 7.130
