I don't have much time for a detailed answer, so the short answer:
Nodebus is 802.3, but not Ethernet. AP20 systems don't interface to
outside networks. You need an AW51 or AW70 that has two Ethernet ports
... One for nodebus, one for your network.
On the 51 or 70 box, you need AIM*API applications to access the
historian. Foxboro describes these on the website.
It's relatively easy to access historical data in I/A, it just costs
some money to get the hardware and software infrastructure to do it.

Subject: [foxboro] Questions about Foxboro, Venix 2.1 and informix...
I have to do something in a Foxboro running Venix 2.1 and Informix. What
i have to do is to make some app that save the history of some variables
and send it over an ethernet network. I have never used Foxboro so I am
quite lost here.
I was thinking about making remotely (from a normal PC) queries in the
informix DB to retrieve the historics values that, supposedly, are
stored in the Informix DB. The first problem i found was that i werent
able to access to the informix db. I run isql in both the ap20 and the
three pw workstation and it show me no databases. How can i access to
the db so?
The other thing is how to hook any point of this system to some network
technology used theese days. I read something about NodeBus being some
kind of ethernet modified. Is this possible to hook a normal pc with an
ethernet card to this nodebus and access the network of the ap20 and
pw's?
Finally, i dont know if the historics values are stored in the informix
db or somewhere else. I found out that the alarm history is kept in a
normal txt file.
I would really appreciate any help you could give me about this. And
generally any information about foxboro and venix in general in order to
help me solve this issue.
Thanks in advance!
