Control component

Allows for several types of control operations to be performed on a buffer. On/Off - Standard on off control as used on most overs, toasters, irons. P/PI/PID - Mathematical control process to get to the setpoint as fast as possible, similar to the process in the human brain when steering a car.

Process

Processes an entire buffer, either by performing the control operation to every value in the buffer or just the last value.

Parameters

Value to specify the required control setpoint

Return value

This call does not return a value

ProcessTick

Processes the current value from a buffer.

Parameters
