Re: [foxboro] Data collection software for Sun I/A

Please be careful with programs like Lotus 1-2-3 and omget that do one-shot
gets of data. In general, these programs generate broadcast messages that
disturb every machine on the network.

I'm not sure that Lotus is still available and I'm not sure that it does a
broadcast, but you should check if it does. 

The simplest test is to run /usr/local/show_params before and after using
Lotus 1-2-3 on a number for values from a number of compounds. If the number
for USED entries for OM_NUM_IMPORT_VARS does not change the first time you
run it, it is likely that Lotus is broadcasting.

Hope this is useful to you.

Ken,
Where would the spreadsheet get the data? Would it be from the historian?
If so, we would have to remove any exception handling when we are doing a
collect. We are using the legacy historian so that might be too practical,
since we need to stop the historian to edit the historian tags.
If the data doesn't come from the historian, this might be a slick solution
providing that we can specify the times in the future and a a one second
data rate.

I believe that Lotus on Sun boxes has Foxboro extensions that can =
snapshot process block data. You could set up a spreadsheet template for =
one row, duplicate the rows, and then edit/replace the block names in =
each row. You could export that spreadsheet using TCP/IP to whatever =
machine/tuning package you desire.

If you are looking for some sort of heuristic tuning as found in some of =
these third party packages, I'm curious as to why you don't use the =
exact block? Is it that bad?

Hey list,
We are looking for a new method to get data from our unix based I/A =
systems
(AW51E) for loop tuning. I am currently looking into OPC servers which =
seem
to work well but require block configuration at both the OPC server and =
OPC
client side. It is also very expensive. What I would like is a simple
application where I can type in the tags I'm interested in (typically
PID.MEAS, PID.SPT PID.OUT) and the sample rate. The application would =
then
put the data in a file in ASCII format. I thought before I wrote =
something
I'd see what your using.

Thanks in advance for your help.
