Hi Frits,
I set up an Apache server on an AW51B a few years ago to get information
out to users that didn't have (or didn't want) Exceed. I set up a simple
script to omget about a hundred key values and write them to a text file.
I then read the file with a perl script and generate an html document. This
is quick and easy, and I update the html document every two minutes. I
include a command in the html to have the browser request a new page every
minute, so users are pretty much kept up to date. Some users keep their
browser open to this page all day long. The only cost was my labor ( I
work cheap!) because Apache is free nobody needs Exceed or DM licenses to
look at the plant. One of these days I might look into two way
communication for control, but that is not required by most users because
they only want to see what their operators are up to.
I kept the web page as sparse as possible - no graphics only a few
tables of information. This kept the size down to a minimum, and there is
no perceptible load on the system.

Subject: Browser access to Foxboro graphics.
Hi all,
I've just recently put a web server (Apache) on one of my WPs to have very
easy access to reports and the like.
This is particularly useful for the maintenance group. They don't have to
log in any more to get various status reports
out of the system about the mechanics of the Casting machine. It's all
there, available on their browser.
In fact, I use in now a lot myself. All I want to know is pre-cooked (cgi
scripts) and up to date :-)
What I want to know is if anyone in our group have done some work to get DM
or FoxView style graphics available
with a browser, perhaps using Java (my weak point at the mo) .That would be
the topping on the cake.
Cheers,
Frits Schouten.
