6.1.4 Double precision integer type (DINT) Boolean type (BOOL) conversion DINT_TO_BOOL
DINT_TO_BOOL_E
Double precision integer type (DINT) data is converted into Boolean type (BOOL) data.
Function definition
BOOL DINT_TO_BOOL ( DINT S1 );
Argument
Argument Name IN/OUT Description
S1 IN Data to be converted (BIN 32-bit data)
Return value
Return Value Description
BOOL Conversion result (bit data)
Remarks: When the data to be converted (BIN 32-bit data) is 0, the return value is "0".
When the data to be converted (BIN 32-bit data) is other than 0, the return
value is "1".
Example of use
Argument Type ST Program Conversion Result Used Instruction
DINT M100 :=
DINT_TO_BOOL(di_data1);
LDD<> di_data1 K0
OUT M100 LDD<>, OUT
Function definition
BOOL DINT_TO_BOOL _E( BOOL EN, DINT S1, BOOL D1 );
Argument
Argument Name IN/OUT Description
EN IN Execution condition (Function is executed only when the result is TRUE)
S1 IN Data to be converted (BIN 32-bit data)
D1 OUT Conversion result (bit data)
Return value
Return Value Description
BOOL Execution condition
Example of use
(*
(*
(* When execution condition X0 turns ON, the double precision integer type
(DINT) data in dData is converted into the Boolean type (BOOL), and the
result is stored into Result.
M0 := DINT_TO _BOOL_E ( X0, dData, Result ) ;
