fixed output value range. Conversion may be required through a calculation chan-
nel.
Process variable (x) : Source channel for the process variable. An analogue input is
normally used as the source.
Controller type: Type of controller : P, PI, PID, PD or I controller
P term (Kp) : The P part of the controller, i.e. the proportional gain, Kp. Altern-
atively to manual configuration, you can control Kp via a channel, for example, via
a slider from a visualisation system.
I term (Ti) : The I term of the controller, i.e. the integral time, Tn. Alternatively to
manual configuration, you can control Tn via a channel, for example, via a slider
from a visualisation system.
D1 term (Td) : The first D term of the controller, i.e. the derivative time Td. Altern-
atively to manual configuration, you can control Td via a channel, for example, via
a slider from a visualisation system.
Delay time : By enabling this option, you can switch the first D term of the con-
troller from difference to time delayed difference. We recommend enabling this
option.
Start value I term : Depending on whether the I term is activated (see controller
type), here you can choose to give the start value of the I term or the zero point of
the manipulated value (y).
