S7 1200 HW Identifier

Hi,

I was referring attached image in TIAV14 software, i am bit confuse on when to used which HW Identifier number. As you can see that there are different HW identifier named Local~MC, Local~Common etc... What are they.? Whats the used of individual? I have read LED information using Local~Common. Why there are so many identifiers for single CPU? Again for CPU there is one HW Identifier. Its confusing for me.

vinit

.... Its confusing for me.

For me also.

Sometimes you need HW_ID instead of LADDR for CPU1500 function calls.

It is realy confusing.

It is TIA.

Hi, for me as well but it is any answer yet.

Thanks!
