5 MELSEC FUNCTIONS
5.10.9 32-bit data logical sum (3 devices) DOR_3_M
The specified two BIN 32-bit data are ORed bit by bit.
Function definition
BOOL DOR_3_M (BOOL EN, ANY32 S1, ANY32 S2, ANY32 D);
Argument Name
IN/OUT
Description
EN IN
Execution condition (Function is executed only when
the result is TRUE)
S1
IN
Data to be ORed (BIN 32-bit data)
S2
IN
Data to OR (BIN 32-bit data)
D
OUT
Operation result (BIN 32-bit data)
Remarks: For bit devices, the bits greater than in the digit specification are
processed as "0 (zero)".
Return Value
Description
BOOL Execution
condition
Example of use
(* When execution condition X0 turns ON, the 32-bit data in dwData1 and the *)
(* 32-bit data in X20 to X3F are ORed, and the result is output to Result.
*)
DOR_3_M (X0, dwData1, K8X20, Result);
