Let me try and explain this by using Allen-Bradley as an example.

I'm trying to go into a DINT and physically alter each bit in it. In Allen-Bradley(RSLogix500) I can simply click on the tag name and a drop down box appears in which it displays each bit and in turn i can alter it.

Now when I go to siemens, i do not get the same dropdown box. Anyone know how to do this?

I read something about using the "AT" command, however i'm not sure how to implement it(also the data type AT does not appear in the siemens i am using..TIA Portal V11)

So does anyone have any ideas?

Let me know.
