Decode; Encode - Mitsubishi Electric MELSEC Q Series Programming Manual

5 MELSEC FUNCTIONS

5.14.5 Decode

The lower n bits of the specified data are decoded.
Function definition

5.14.6 Encode

n
2 bits of data, starting at the specified data, are encoded.
Function definition
5 - 61
DECO_M
BOOL DECO_M (BOOL EN, ANY_SIMPLE S1, ANY16 n, ANY_SIMPLE D);
Argument Name
EN
S1
n
D
Remarks: The DINT, REAL and STRING types cannot be used in arguments S1" and
"D".
Return Value
BOOL Execution condition
Example of use
(* When execution condition X0 turns ON, the lower Bit Size bits of D100 are
(* decoded, and the decode result is stored into 2
DECO_M (X0, D100, BitSize, Result)
Corresponding MELSEC command
DECO (8 256 bits decode)
ENCO_M
BOOL ENCO_M (BOOL EN, ANY_SIMPLE S1, ANY16 n, ANY16 D);
Argument Name
EN
S1
n
D
Remarks: The DINT, REAL and STRING types cannot be used in argument S1".
Return Value
BOOL Execution condition
Example of use
(* When execution condition X0 turns ON, 2
(* encoded, and the result is stored into Result.
ENCO (X0, D100, BitSize, Result);
Corresponding MELSEC command
ENCO (256 8 bits decode)
IN/OUT
Execution condition (Function is executed only when the
IN
result is TRUE)
IN Data to be decoded
IN Valid bit length (1 to 8) *0: No processing (BIN 16-bit data)
OUT Decode result
For the usable data type, refer to "3.2.2 About
ANY type".
IN/OUT
