5.15 L_DcBitShift - shift operation
This FB carries out a bit shift operation with a "DINT" value.
• The shift factor, i.e. the number of bits by which the input value is shifted to the left or right, is
defined by a parameter.
• The result of the shift operation is output at the output dnOut.
• The sign remains.
