Thanks for the replies.
First, I am more of a DCS guy than a PLC guy, so I may be not using quite the right terms possibly. Lately I'm constantly getting requested to build interfaces between the DCS and PLCs. And because Honeywell can make really amazing decisions (/s) on how they approach things, I'm being forced to build a lot of my interfaces using UDTs. Which is a nightmare for a whole slew of reasons, but sometimes you just have to do what the client wants.
I don't feel like I'm explaining myself well here, so maybe some screenshots would help.
In the Rockwell Help files, it seems to say you can copy and paste from excel into the Data Type Editor. But no matter what I do, it tries to put everything I'm trying to paste into the first 'cell' of the data type editor table. And I can't seem to find any further detail as to how to do this properly or what exactly it is I am doing wrong. Or am I just completely misunderstanding what the help file says and you cannot copy a table of data and paste into the data type editor?
