SimpleWriteValueCoil

SimpleWriteValueCoil (FB)

FUNCTION_BLOCK SimpleWriteValueCoil

Representation

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

In this configuration, compiler error messages of type C0032 are generated, a download is not possible.

Remedy:

Use of an intermediate variable of the explicit type WORD directly at the output of the type conversion operator. Connecting the intermediate variable at the input InputValue.
