Parameter
Type
Comment
Input_Var
INT, DINT
Variable on which the shift is to be performed.
Example: Input_Var = 2#1000000011110001.
Shift_Num
INT
Value of the shift to be performed.

The following table describes the output parameters:
Parameter
Type
Comment
Shifted_Var
INT, DINT
Shifted_Var contains the value of Input_Var shifted by the number of bits given by Shift_Num. The shift register is filled with zeros.
Example: with the data examples of the previous table, the result is the following Shifted_Var = 2#0000100000001111
Shifted_Bits
INT, DINT
Shifted_Bits contains the shifted bits.
Example: with the data examples of the previous table, the result is the following Shifted_Bits = 2#0001000000000000
