6 IEC FUNCTIONS
6.1.4 Double precision integer type (DINT)
Double precision integer type (DINT) data is converted into Boolean type (BOOL) data.
Function definition
Function definition
6 - 6
BOOL DINT_TO_BOOL ( DINT S1 );
Argument
Argument Name IN/OUT
S1 IN
Return value
Return Value
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
DINT M100 :=
DINT_TO_BOOL(di_data1);
BOOL DINT_TO_BOOL _E( BOOL EN, DINT S1, BOOL D1 );
Argument
Argument Name IN/OUT
EN IN
S1 IN
D1 OUT

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 ) ;
