Produced and Consumed Tags in Studio 5000

Since its rare to P/C a single tag and instead to use an array or a UDT, I create these I use the naming format PLCNAME1toPLCNAME2 for the tag array at both ends. That way just from the name you know the source and destination of that tag group.

Tim, great video.
I have a quick question. Is this basically the same thing as using a MSG instruction? In what situation would you want to use one or the other if so?
Thanks.
