Well, it's been a fun day "upgrading" our historian to AIM*AT on our AW51E. It's finally working, but I need to mention a very large omission in the AIM*AT installation instructions: If your historian has more than 1200 points, which it probably does, you MUST do the following: 1. cd /opt/aim/bin, or wherever you installed AIM*AT on your AW51. 2. Edit the file called "aimapi.cfg". As shipped, the file has one line. You must add a line to this file with your favorite text editor that looks like this: maxobj = (# of points that your historian is licensed for) e.g. maxobj = 20000 If you fail to add this line, your AIM*Historian will only collect the first 1200 points. Isn't that special? This little tidbit does not appear in the documentation, the Release Notes, or anywhere in the 1-week AIM*AT class I just took in FoxMass. Also, you may already know this, but it's a good idea to reiterate: if you have recently deleted a large number points from your CSA database, make sure to also delete these points from your Historian. All Historian packages use either AIS, AIM*API or FoxAPI to establish connection lists to the C:B.P points, and if the C:B.P's aren't there, it will take a long time for either AIS, AIM*API or FoxAPI to start up. I should have seen that one coming, but FoxHistory is weird about deleting points. They don't really get deleted, they just don't get collected or count toward your license amount. Deleted points stay in your configuration forever, taking up index points. They show up in red on the GUI, and you can undelete them later if you want. I was concerned that if I "deleted" points that I had removed from the CSA, that I could no longer retrieve them from tape archives. Turns out, you can retrieve them, since they never really get deleted. Ah, just another wonderful day in Foxboro-land!
