In the Control Loop Library package are multiple example projects, including one for the filters. Program containing: GVL.filterIIR( xEnable:= GVL.xEnableFilter, lrValue:= GVL.lrYOriginal, lrFilteredValue=> GVL.lrOutputIIR); GVL.filterFIR( xEnable:= GVL.xEnableFilter, lrValue:= GVL.lrYOriginal, lrFilteredValue=> GVL.lrOutputFIR); GVL.filterSOS( xEnable:= GVL.xEnableFilter, lrValue:= GVL.lrYOriginal, lrFilteredValue=> GVL.lrOutputSOS); GVL containing aCoefficientsA_IIR : ARRAY[0.. 4] OF LREAL := [1,-2.3695130071820376,2.31398841441588,-1.0546654058785676,0.18737949236818494]; aCoefficientsB_IIR : ARRAY[0.. 4] OF LREAL := [0.0048243433577162282,0.019297373430864913,0.028946060146297369,0.019297373430864913,0.0048243433577162282]; filterIIR : Ctrl.Filter_IIR := (palrCoefficientsA:= ADR(GVL.aCoefficientsA_IIR), udiSizeCoefficientsA:= SIZEOF(GVL.aCoefficientsA_IIR), palrCoefficientsB:= ADR(GVL.aCoefficientsB_IIR), udiSizeCoefficientsB:= SIZEOF(GVL.aCoefficientsB_IIR)); aCoefficientsB_FIR : ARRAY[0.. 5] OF LREAL := [0.01982722552692669,0.1325131219866022,0.34765965248647102,0.34765965248647107,0.13251312198660226,0.019827225526926694]; filterFIR : Ctrl.Filter_FIR := (palrCoefficientsB:= ADR(GVL.aCoefficientsB_FIR), udiSizeCoefficientsB:= SIZEOF(GVL.aCoefficientsB_FIR)); aCoefficientMatrix_SOS : ARRAY[0.. 1] OF Ctrl.FilterCoefficients_SOS := [(b0:= 1, b1:= 2, b2:= 1, a0:= 1, a1:= -1.048599576362609, a2:= 0.2961403575616683), (b0:= 1, b1:= 2, b2:= 1, a0:= 1, a1:= -1.320913430819428, a2:= 0.6327387928852787)]; lrG : LREAL := 0.004824343357716228; filterSOS : Ctrl.Filter_SOS := (paCoefficientMatrix:= ADR(GVL.aCoefficientMatrix_SOS), udiSizeCoefficientMatrix:= SIZEOF(GVL.aCoefficientMatrix_SOS), lrGain:= GVL.lrG); lrX : LREAL; lrYOriginal : LREAL; lrOutputFIR : LREAL; lrOutputIIR : LREAL; lrOutputSOS : LREAL; xEnableFilter : BOOL := TRUE;

Hi everybody, I want to execute more than once cam fb simultaneously so blending cam and thus blending velocity without stop motion. But as far I know codesys dont support directly cam blending. But I beleeive there is a some solving. I request your support. But there is important thing is I want to change cam table cam on the fly. For example FlyingSaw application change cutting lenght.

I had a similar issue before, and in my case, it was resolved by ensuring the correct target device was selected and that the boot application was properly downloaded and set to start automatically. https://forge.codesys.com/forge/talk/Engineering/thread/fce611429a/duck life
