P9002¶

Code: P9002
Message: Set of valid source files has no content

This error occurs when the set of valid source files has no content, meaning no valid Structured Text code was provided for compilation.

Example¶

This error typically occurs when:

No source files are provided to the compiler
All provided source files are empty
All provided source files contain only comments or whitespace

To fix this error, ensure that at least one source file contains valid Structured Text code:

(* This is a valid Structured Text program *)
FUNCTION_BLOCK Example
VAR_INPUT
    Input1 : BOOL;
END_VAR
VAR_OUTPUT
    Output1 : BOOL;
END_VAR

Output1 := Input1;
END_FUNCTION_BLOCK
