Post by mubeta on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
This is normal and correct since in CoDeSys static addressing of variables uses the IEC method. A LONG tag has the size of 8 bytes, so %ML0 coincides with %MB0 ... %MB7; %ML1000 with %MB8000 ... %MB8007. (Similar reason for word and other formats). Also the reason the compiler won't let you map the structure to a %MW depends on the fact that the individual base elements are manipulated to 64 bits regardless of the smaller size. That said, it makes me strange that you cannot write a parser without making use of static memory allocation.
