SimpleWriteValueFloat

SimpleWriteValueFloat (FB)

FUNCTION_BLOCK SimpleWriteValueFloat

Use of type conversion operators (e.g. INT_TO_REAL) directly at the input 'InputValue'

In this constellation, compiler error messages of type C0032 are generated, download is not possible. Remedy: Use an intermediate variable of explicit type REAL directly at the output of the type conversion operator. Connect the intermediate variable to the input 'InputValue'.
