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.

Action

The Floating component has the following action:

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