CharCurve_DINT (FB) ¶ FUNCTION_BLOCK CharCurve_DINT This function block will evaluate a piecewise linear function (the characteristic curve) at an integral point \(x \in \mathbb{Z}\) . The characteristic curve is specified by a defined number of integral sampling points \((x_{1}, y_{1}), \dots , (x_{n}, y_{n}) \in \mathbb{Z^{2}}\) InOut: Scope Name Type Comment Input diInputValue DINT interpolation point \(x \in \mathbb{Z}\) usiNoPoints USINT number \(N\) of sampling points defining the characteristic curve ( \(2 \leq N \leq 11\) ) Inout ap2diPoints ARRAY [0..10] OF POINT2_DINT array of \(N\) two dimensional sampling points \((x_{i}, y_{i})\) with \(1 \leq i \leq N\) Output diOutputValue DINT interpolated value at point \(x \in \mathbb{Z}\) xError BOOL error flag wErrorID WORD information on error 0: No error 1: error within array of sampling points (i.e. the sampling points aren’t arranged in ascending order) 2: interpolation point diInputValue is outside of area covered by sampling points ( \(x \notin [x_{1}, x_{n}]\) ) 4: invalid number of sampling points

CharCurve_LREAL (FB) ¶ FUNCTION_BLOCK CharCurve_LREAL This function block will evaluate a piecewise linear function (the characteristic curve) at an integral point \(x \in \mathbb{R}\) .

signals ¶ MeasureFrequence (FunctionBlock)

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 \(3 \cdot \mbox{lrFrequency}\)
