Page 236: Explanation Of Controller Function
® ABB i-bus Appendix 12.4 Explanation of controller function The various control types possible with this device are described below. 12.4.1 2-point controller A 2-point controller possesses two output states (On/Off) that change depending on the actual value. If the actual value is higher than the parametrized setpoint, the associated control value is 0.
Page 237 ® ABB i-bus Planning and application Correctly adjusting the hysteresis can also limit the number of relay operating cycles. Example: If the heating-operation setpoint is 21 °C and the hysteresis is 1.0 K, the controller will switch on when the temperature falls below 20.5 °C and will switch off again when the temperature exceeds 21.5 °C.
Page 238: Pulse Width Modulation (Pwm)
® ABB i-bus Appendix 12.4.1.1 Pulse width modulation (PWM) With pulse width modulation, the valve is operated as with 2-point control exclusively in the positions fully opened and fully closed. In contrast to 2-point control, the position is not controlled via limit values, but rather by calculated control values similar to continuous control.
Page 239 ® ABB i-bus Planning and application 12.4.1.1.1 Example When the device receives a 1-byte control value (continuous control) as an input signal, this value together with the parameterized cycle time from a PWM calculation is converted into a signal for 2-point control (ON-OFF-ON).
Page 240 ® ABB i-bus Appendix 12.4.1.1.2 Calculation With pulse width modulation, control is implemented by a variable mark-space ratio. Fig. 30: Calculation During the time t the valve is opened and during the time t it is closed. On account of t = 0.4 x t...
Page 241: Pi Controller (Continuous)
® ABB i-bus Planning and application 12.4.2 PI controller (continuous) 12.4.2.1 Continuous control With continuous control, a control value is calculated based on the setpoint temperature and the actual temperature, and is used to optimally set the temperature. The valve is brought to a position corresponding to the calculated control value.
Page 242: Pi Controller (Pwm)
® ABB i-bus Appendix 12.4.3 PI controller (PWM) The PI controller (PWM) basically operates exactly like the PI controller (continuous). The only difference is that the control value of a PI controller (PWM) is converted to a 1 bit PWM switch-on/switch-off ratio before it is output.
