Figure 5-14 Example: technology controller as a level controller
The technology controller specifies the speed setpoint of the motor in such a way that the
process variable to be controlled corresponds to its setpoint. The technology controller is
designed as a PID controller, which makes it highly flexible.
The technology controller setpoint can be supplied via the same setpoint sources as those
available for the speed setpoint. The technology controller is also equipped with its own
motorized potentiometer and own fixed frequencies.
The setpoints, actual values, and control signals of the technology controller are defined by
means of BICO technology.
