    hi FAE
    the question I faced was that I want to save the interpolator points being output by FBD into a document for txt. and then plot these points to a curve line by tool of Excel or Matlab. so how can I do it? expect to your replay!

    would recommend to use:
    SMC_AxisDiagnosticLog from sm3_basic library
    Execute the fb in the motion task:

    SMC_AxisDiagnosticLogInstance(bExecute:=TRUE ,bCloseFile:= FALSE,sFileName:= 'schreibs_da_rein.txt',
    bSetPosition:= TRUE,bActPosition:=TRUE,bSetVelocity:= TRUE,bActVelocity:=TRUE,
    bSetAcceleration:=TRUE, bActAcceleration:= TRUE,Axis:=Drive);

    additional needed is to call the file writing in an file task
