In this example, the input variable input_value is declared. However, you can write a constant (e.g.
16#45 for 45°) directly at the input contact of the function.
Body
In the body, the value 90° is assigned to the variable input_value. When the variable start is set to
TRUE, the function F300_BSIN is carried out. It stores the result in the variable output_value. If
the input_value is between 181° and 359°, output_value has a minus sign. The function
WORD_TO_BOOL sets the variable input_181_to_359 to TRUE. With an input_value of 90° or
270°, the output_value is 1, which represents the value before the decimal point. If this is the
case, then WORD_TO_BOOL sets the value of the variable input_90_or_270 to TRUE.
