I am familiar with the Legacy Historian but I was recently at a plant where they had the new AIM* Historian. It was installed on a Sun machine. I really like the fact that you can change its configuration without shutting it down. This allowed us to tighten many deadbands specifically for the tests we were running without impacting their normal data collection. There is a GUI configuration program for Solaris and it is not too bad. We had a strange problem trying to enter new deadband number for a few points. For some reason it would not accept the number we wanted to enter. So instead we ended up entering 0.0 which worked.
The main thing I didn't like was the data extraction capabilities. It may be that there is a better tool, but the only one I could find was the Data Display function. This is much improved over the same program for the Legacy Historian but it is still a pain to use for extracting a large amount of data. I ended up having to extract 63 separate files to get all the data we needed. It then took me about 6 hours to merge all that data into a single Excel file. On our Legacy system we use a program called ProcIns_extract to extract data and it is much easier to use. I am always amazed that Historian developers and vendors don't include a simple program to extract data to a text file in their base system. Westinghouse has the same problem as Foxboro in this area.
