5 - 51
BOOL DROR_M (BOOL EN, ANY16 n, ANY32 D);
Argument Name
EN
n
D
Remarks: When a bit device is specified in "D", the data in the specified number of
digits are rotated.
Return Value
BOOL Execution condition
Example of use
(* When execution condition X0 turns ON, the 32-bit data in dwData1 are
(* rotated to the right by the number of bits stored in D0, without the carry flag *)
(* being included.
DROR_M (X0, D0, dwData1);
Corresponding MELSEC command
