Hi Heinrich,
I'm having a bit of difficulty  with your email because to me
data acquisition and archiving are fairly disjunct issues.
In my experience the channel archiver is a wonderful tool (even if
we still largely use an older version), and it allows you to
archive whatever channel from whatever board.
As data acquisition goes, depending on what you're trying to do,
if it's serial lines, what's wrong with just using devices
plugged into terminal servers? - We mostly use extra VME boards
only for more special things (like e.g. b016 boards for array
controllers, and in some cases have used custom mezzanine boards
built by instrument builders)
?
Aloha,
Maren

Hello
We have a project were we want to monitor some values (some analog some
digital)
This is mostly for archiving and then later reviewing to determine if
equipment is working as it should over longer periods of time.
Also to try and determine if some equipment would need to be replaced
ahead of the time when failure occurs.
So far we've considered the national instruments cards. As they can do

all the I/O we require.
They are also fairly easy to interface using DotNet.

But there is already a channel archiver for EPICS which I think is worth

using maybe?

I know there are some Linux drivers for NI cards. Haven't looked at them

yet.
But maybe there is some other card or system I can consider for this
project?
Thanks for your time
