Description of the parameters
The following table describes the input parameters:
Parameter
Type
Comment
Input_Var
INT, DINT
Variable on which the shift is to be performed.
Example: Input_Var = 2#10000000111100010000000011001111.
Shift_Num
INT
Value of the shift to be performed.
Example: Shift_Num = 6.
The following table describes the output parameters:

Type
Comment
Shifted_Var
INT, DINT
Shifted_Var contains the value of Input_Var shifted by the number of bits given by Shift_Num. With conservation of the sign and propagation of the sign bit in the bits liberated by the shift.
Example: with the data examples of the previous table, the result is the following Shifted_Var = 2#1 1111110000000111100010000000011
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#00000000000000000000000000001111
