Message: Type '<pointer type>' possibly not convertible to type '<data type>' .

Possible error cause: This error occurs only when checking pool objects. An attempt was made to convert a pointer to an integer. Because the size of pointers in a library is unknown, errors may occur when using the library.

Error correction: Use the type ‎__UXINT‎ or ‎__XWORD‎ for platform-independent calculations with pointers.

Example of the error:

PROGRAM PLC_PRG
VAR
    ptr : POINTER TO INT;
    dw : DWORD;
END_VAR
    dw := ptr;

--> C0033: Type 'POINTER TO INT‘ possibly not convertible to type 'DWORD‘.
