SimpleWriteValueCoil

SimpleWriteValueCoil (FB)

FUNCTION_BLOCK SimpleWriteValueCoil

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

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