Lexical Error (LEX0002): Invalid direct variable '...'.

In an ST code worksheet, the lexical analysis detected an invalid direct addressing of a variable (using a location prefix I, Q or M, the % character and a size prefix X, B, W etc.). The affected code position is underlined in the worksheet.

This type of addressing is not supported in PLCnext Engineer, regardless of the present lexical error. Addressing is done exclusively by assignment to a process datum in the Data List.

Remedy

Double-click the error message to jump to the affected editor position.
Remove direct addressing from the relevant line of code.
