Part II IEC Instructions
DINT_TO_BOOL
DOUBLE INTEGER into BOOL
To add an enable input and enable output to the instruction, select [With EN/ENO] from the
"Instructions" pane (LD, FBD or IL editor). To reuse an instruction select "Recently used" from the
context menu or press <Ctrl>+<Shift>+<v> in the programming window.
PLC types Availability of DINT_TO_BOOL (see page 1319)
If the input value = 0 (16#0000), the conversion result will be = 0 (FALSE); in any
other case, it will be = 1 ( TRUE).
Data type I/O Function
DINT input input data type
BOOL output conversion result
If the variable DINT_value has the value 0, the conversion result is FALSE, in any
other case TRUE.
Description
DINT_TO_BOOL converts a value of the data type DINT into a value of the data type BOOL.
Data types
Example
In this example, the same POU header is used for all programming languages. For an example
using IL (instruction list), please refer to the online help.
POU header
All input and output variables used for programming this function have been declared in the POU
header.
In this example the input variable (DINT_value) has been declared. Instead, you may enter a
constant directly at the input contact of a function.
Body
DINT_value of the data type DOUBLE INTEGER is converted into a value of the data type BOOL.
The converted value in written into Boolean_value.
LD
ST
When programming with structured text, enter the following:
Boolean_value:=DINT_TO_BOOL(DINT_value);
