Function definition
Function definition
6 - 10
Boolean type (BOOL) conversion
BOOL INT_TO_BOOL ( INT 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 16-bit data) is 0, the return value is "0".
When the data to be converted (BIN 16-bit data) is other than 0, the return
value is "1".
Example of use
Argument Type
INT b_data1 := INT_TO_BOOL( i_data1 );
BOOL INT_TO_BOOL _E( BOOL EN, INT 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 integer type (INT) data in iData is
(* converted into Boolean type (BOOL) data, and the result is stored into Result.
M0 := INT_TO_BOOL_E( X0, iData, Result ) ;
