Conversion instructions
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 input_value is declared. However, you can write a constant
directly at the input contact of the function instead.
Body
When the variable start is set to TRUE, the function is carried out. It converts the floating point
value -1.234 into the whole number value -2, which is transferred to the variable output_value at
the output. Since the whole number may not exceed the floating point value, the function rounds
down here.
LD
ST
When programming with structured text, enter the following:
IF
start
THEN
F327_INT(input_value, output_value);
END_IF;
