[?]: assign an alias tag for another tag in RSLogix5000

[Goran]

my question is about assign an alias tag for another tag in RSLogix5000.

for the first, I create user defined data types like - Tank and tank have 2 tags - level switch (bool), temperature meauserment (int).
I create this defined data type and it is OK.

but in tag editor, when I want to link my 2 tags (switch and temperature) to real inputs like Local:2:O.Data[0].1 and Local:12:I.Ch12Data I can not do that.

I find in Programing manual 1756-PM0001 on page 53 organizing tags that is posible, but I can do that. In cell does not displays a t.

Can you help me?

Sorry for my englis.
