MeasureFrequence (FB) ¶ FUNCTION_BLOCK MeasureFrequence This function block will measure the average frequency of an input signal over a defined number of periods. Note The function block has to be called with a frequency higher than the maximum frequency of the input signal to be able to calculate the correct result. InOut: Scope Name Type Initial Comment Input xEnable BOOL Reset xInput BOOL Input signal usiPeriods USINT (1..10) 1 Number of time periods the frequency shall be averaged in ( \(1 \leq \mbox{number} \leq 10\) ) Output lrFrequency LREAL Avareged frequency (in Hz) xValid BOOL Validity of result FALSE : If the required number of time periods has not yet been passed or if the distance in time of two raising edges exceeds \(3 \cdot \mbox{lrFrequency}\)

ProjectPointOnLine (FUN) ¶ FUNCTION ProjectPointOnLine : BOOL This function will project the point \(x \in \mathbb{R^{3}}\) onto a straight line: thereby, the direction vector of the straight line is taken as normal vector of a plane that is moved along the line as long as it touches the point \(x\) . The intersection point of the plane with the line corresponding to this location is the projected point. InOut: Scope Name Type Comment Return ProjectPointOnLine BOOL Input pline POINTER TO LINE_3D Pointer on straight line pvOrig POINTER TO Vector3D Pointer on point \(x\) to be projected pvProj POINTER TO Vector3D Pointer to projected result
