FCU_PI

The FCU_PI component is a regulator with proportional and integral actions.

The FCU_PI component

The FCU_PI component has the following slots:

Enable: enables or disables the component–if the component is disabled (the Enable slot is set to false), the Out slot is set to 0;
Cv: the numeric input slot with the controlled value;
Sp: allows to set the setpoint for controlled value;
Out: the output slot of the component;
Kp: allows to set the value of proportional gain constant;
Ti: allows to set the value of the integral time constant (setting the slot to 0, disables this integral action);
Max: allows to set the maximum value of the output of component;
Min: allows to set the minimal value of the output of component;
Bias: allows to set the bias value–this value is added to the Out slot if Ti slot is set to 0;
Max Delta: allows to set the maximum amount the Out slot can change by in the exTime (setting to 0 disables this function);
Direct: allows to set the acting process;
- Available settings: true (direct-acting process), false (reverse the acting process);
Ex Time: allows to set the period of loop execution;
Pgain: shows the value of the output signal, which was calculated by the proportional action;
Igain: shows the value of the output signal, which was calculated by the integral action.
