Controllers

The following are available as controllers:

 

Controller (with external set value) (Component 12)

Value Transmitter (Component 36)

Controller (Type 2: internal set value) (Component 39)

Value Transmitter Switch (Component 48)

Controller (external set value and switch) (Component 69)

Mass multiplier (Component 110)

PID-Regler (with Anti-Windup) (Component 130)

Transient separator (with transfer function) (Component 131)

Quantity Converter  (Component 168)

 

Due to the possibility of parallelization you can no longer rely on a certain processing sequence of the components. This is why two new specification values have been implemented in the components 12, 39, 69:

• By means of FSEQ you can specify whether these components are to be calculated in parallel with other components or only after the other components. This flag is also available for the programmable components 65 and 93.
• For the controllers, ITSTEP specifies how often the controller is active (ITSTEP=1: in every step; ITSTEP=2: in every second step;…). In the steps in between (dead time), the controller again sets the same value as in the latest active step.

 

Controller for electrical lines

Frequency, voltage and power are mapped internally to mass flow, pressure and enthalpy. F, V and Q can be used directly as starting values for controllers.
