SimpleWriteValueInt

SimpleWriteValueInt (FB)

FUNCTION_BLOCK SimpleWriteValueInt

Use of type conversion operators (e.g. REAL_TO_INT) directly on the input 'InputValue'

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