Arguments
IN
IN
DINT
Any integer value
NbR
NbR
DINT
Number of 1 bit rotations (in set [1..31])
ROR

no effect if NbR <= 0
Example
(* FBD Program using "ROR" Function *)
lrsf_ror3
(* ST Equivalence: *)
result := ROR (register, 2);

(* register = 2#0011_0011_0010_1011_0011_0010_1001_1001 *)

(* result = 2#0100_1100_1100_1010_1100_1100_1010_0110 *)
