IronPLC can only run very simple programs. The steps described are accurate but many language features are not yet supported.

P0001¶

This error occurs when a comment is not properly closed before the end of the file.

Example¶

The following code will generate error P0001:

TYPE
(* A comment that is never closed
    CustomStruct : STRUCT
        Name: BOOL;
    END_STRUCT;
END_TYPE

The comment starting with (* is never closed with *), causing the parser to reach the end of file while still inside the comment.

To fix this error, properly close the comment:

TYPE
(* A comment that is properly closed *)
    CustomStruct : STRUCT
        Name: BOOL;
    END_STRUCT;
END_TYPE
