DBDOC FC HAS NO INPUT.ERR

This message means that the function block has no wired input, and the value of the spec is not the correct default. In some forms of controller, this can be a problem. Composer usually replaces a removed line with the correct default specification value (5 for real 0.0, for example), but WinCAD and DOS CADEWS do not.

In this example, the compiler is telling us that the unwired input S1 has a value 0, not 5, as it should be.
