Some kinds of indirect addressing are stil possible, I see, but not as powerful/flexible as this. But maybe I'm overlooking something ... I mean something like this: http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&objId=22109932&load=treecontent&lang=en&siteid=cseus&aktprim=0&objaction=csview&extranet=standard&viewreg=WW Quite powerful and useful, but I can't find any info or confirmation yet... Anyone around here who knows more? Thanks in advance, Ronald.

The ANY is present in S7-1500 and should be used without restricitons...(however, with the possibility of "full simbolic addressing" somethings could be found in a easy way, like move structures with MOVE - ":=" - instead with SFC20...).

Yes, symbolic adressing is nice, but I need sometimes the flexibility to copy data fromANY place with ANY length to ANY place which I can change during runtime. The ANY pointer in combination with the construction with the AT instruction in SCL as showed in the sample can do that.(I use it quite often) Yes, I know it can be a potential trouble source, but it's also very useful/powerful/flexible is some cases. Soone can still declare an Any type as Input/Outputon a FB (10 byte ANY pointer) and break it up inside and manipulate itlike in the sample with the AT instruction? That would be good...unfortunately I don't have TIA V12 installed yet to test it... Ronald
