01/02 AWB8230-1413GB PID controlInternal regulator-based calculationsAll calculations within the PID algorithm are carried out inpercentages, so that different physical units can be used, such as• Pressure (N/m 2 ),• Flow rate (m 3 /min),• Temperature (°C), etc.The setpoint <strong>and</strong> returned actual values can, for example, also be<strong>com</strong>pared as percentages.A useful scaling function (PNU A075) is also available. When theseparameters are used, you can define the setpoint directly as therequired physical quantity <strong>and</strong>/or display setpoint <strong>and</strong> actualvalues as physical quantities suitable for the process.In addition, analog signal matching (PNU A011 to A014) isavailable, with which you can define a range based on the fedback actual value signal. The following graphs illustrate the modeof operation of this function.121
