So here it is...
I just recently started thinking about when and why to use alias tags in RSLogix 5000. It is my understanding that an alias tag doesn't reserve the full memory that it's base tag would need. I'm thinking of them as pointers but could be totally wrong. I assume that each alias takes up 32 bit of memory which would be helpful if I wanted to create a duplicate of a UDT. But why would I want to do that?
As of now I came up with only one reason (that is questionable...), and that would be to create an interface to a tag that is created in the scope of a different program. That is not possible...
