SA0016: Gaps in structures

Function	Determines gaps in structures or function blocks, caused by the alignment requirements of the currently selected target system. If possible, you should remove gaps by rearranging the structure elements or by filling them with dummy elements. If this is not possible, you can disable the rule for the affected structures using the attribute {attribute 'analysis' := '...'}.
Reason	Due to different alignment requirements on different platforms, such structures may have a different layout in the memory. The code may behave differently, depending on the platform.
Importance	Low

STRUCT
    bBOOL  : BOOL;
    nINT   : INT;                // => SA0016
    nBYTE  : BYTE;
    nWORD  : WORD;
END_STRUCT
END_TYPE

TYPE ST_UnpaddedStructure2 :
STRUCT
    bBOOL  : WORD;
    nINT   : INT; 
    nBYTE  : BYTE;
