Floating

Applicable to library's version 1.0

The Floating component simplifies the control of 3-point valve actuators. This component has the following functions:

analog input, working with PID regulators;
2 digital outputs for dedicated valve actuators (the Up and Down slots);
analog output for dedicated actuators by voltage level (the Out slot, additional device required);
reset function to automatically adjust physical and virtual valve position.

The Floating component

Slots

The Floating component has the following slots:

Status: indicates the current status of the component (OK, Fault).
Out: the voltage value controlled by the Floating component mechanism and transferred to the dedicated actuator;
Up: the digital output for the rising function of a 3-point direct control valve actuator;
Down: the digital output for the lowing function of a 3-point direct control valve actuator;
In: the input value representing the required percentage of the actuator openness;
Deadband: the value limit within which the output deviation from the required value can be ignored;
Drive Time: the time which the actuator requires to change from the fully closed position to the fully open position (expressed in seconds);
Reset: resets physical and virtual valve position.

Out Value	Up	Down	Description
0 V	False	False	Off
4 V	False	True	Lowing
7 V	False	False	Static
10 V	True	False	Rising

The Floating component slots

The Floating component has the following action:

Reset: allows to periodically close the valve in order to synchronize the position of full closure.
