ST_CM_MinersRule_InitPars

Function block-specific structure with initialization parameters, which are analyzed when the function block is initialized.

• nBins defines the number of bins for the stress level. The total number of bins is nBins + 2; the value must be at least one. The first bin of each row contains the stress levels that are less than or equal to the defined minimum; analogously, all values greater than the defined maximum fall into the last bin of each row.
• nBinsMean defines the number of bins for the mean values. The value must be at least one. Two separate bins are added in the first/last column of the Halfcycle Count Matrix, where mean values are kept that are less than or equal to or, respectively, greater than the defined limits.
• fDamage defines the constant damage from the beginning. The total damage is thus calculated from the sum of fDamage and the accumulated damage with respect to the configured Wöhler curve.
• nCycles defines the initial value of the counted half-cycles at the beginning. The total number of cycles is calculated from the sum of nCycles and the current number of input data.
• nChannels defines the number of independent channels. This must be greater than zero.
