Well, we use Aspen IP.21, but we have similar issues. We use a plant prefix, then an underscore, then the I/A tag (minus the compound), like so: HA2_FI100.PNT If the tag is not unique in a plant (it happens sometimes with I/A because the system only enforces tag uniqueness within a compound), we may add part or all of the compound name in there: HA2_R110_FI100.PNT where R100 is the compound name or some abreviation thereof (IP.21 limits standard tag point names to 24 characters). This makes it easier to write scripts to bulk-load the IP.21 system from the I/A configuration. Corey Clingo BASF Corp.

Just loops numbers or combination loop# and area # or something better ? What works best from end user perspective ?

We started using PI last September. It took us a few tries, but once you have it figured out, it is easy to add/delete as needed. Wally Magda IE&C Spec Sr Colorado Springs Utilities PO Box 214 660 W.

PI-SMT is definitely the way to go ... it's an Excel add-in which provides a drop-down menu on the top Excel command line. From that drop-down menu, you can either upload PI configuration data to the spreadsheet, or download from the spreadsheet to the PI configuration. The macros that are employed are exactly the same as the script files you would run if you were doing the configuration in DOS, so I think it should work for older versions of PI also. The most difficult thing, as I remember, was getting the location tags correct ... location1 is an address that points to the source (in our case 101 is our AW51, when I get my other AW hooked up, that will be 102). location2 is the collection group on the DCS (this was the most difficult thing for me to understand, but I'm set up with 2 groups per CP - one for analog points, one for digital points), location3 works with the type of data (we have 3 is 32-bit floating, 5 is digital). This is explained pretty well in the PI manuals, but those CP collection groups really had me going for a while. The pointsource parameter differentiates the type of source device (in our case, F=Foxboro, D=Yokagawa, C=calculated, A=Allen-Bradley, etc). The exdesc parameter holds the DCS C:B.P reference Using discrete inputs requires defining Digital Sets in PI which hold all the potential values that the input may be. For example, you might have a Digital Set called VALVESTATESET which contains the values Open, Closed, Opening, Closing, Mismatch ... these would correspond to the various values that a GDEV.STAIND might return. That way, rather than seeing the STAIND integer values in your PI archive, you'd see the text values. Everything else I think is fairly straightforward.
