Searching for webserver board/module with some I/O

For a demo project we want to use a webserver interface to some simple
hardware. The initial demo will be 3 devices and after that a very small
annular volume. For that reason we don't want to invest too much in
hardware/software development and are searching for an off the shelf
product. I thought I would find that in a minute, but so far I have
been unsuccessfull. What we would like:

- Module or board (will be built in control box)
- Ethernet (10/100)
- 2 analog inputs
- 2 analog outputs (or PWM)
- 2 digital inputs
- 2 digital outputs
- Stepper motor control, but this can be with external hardware
  and 'step' output only. Limited frequency and accuracy
- Webserver with a few static web pages for reading/writing values
- Upload of pages
- Run a simple "control loop" (example: Aout = Ain * m + b)
- Control the stepper motor step frequency
- Configurable fixed ip address
  Can be like on routers: reset to default and config via web
  But other methods welcomed as well
- Web pages, control software and configuration stored stored in
  NV memory

Anyone know anything that will fulfill (most of) the above?

With the exception of the stepper control software, I think that
everything you need is available here:

Feel free to contact me offline (remove XXX) if you need more
details.

For example a Freescale Coldfire v2 (MCF5223X) demo board should do the
trick.

Looks like this board has most of the hardware we require. But how about
the software? Ideally there should be ready to run software to which
I can add some small control functions and supply the html for the web
pages. The 'ready' software should at least cover TCP/IP (including a
means of setting op de IP adress and related stuff) and a webserver.

The luck that is ordained for you will be coveted by others.

I did browse Sparkfun but did not stumble on this one as I was not looking
for a PIC development board. :-)
Again, looks like usable hardware but seems to require a fair amount of
software development. Or did I not understand it correctly an can I just
upload some html pages and a control loop?

Yes, there are a lot of devboards out there with the required hardware.
But the trick is finding one with software that can be used without, or
with little, modification and that allows a user/installer/our customer
to change the IP adress without a compiler or other 'complicated' tools.

Thanks all for the responses so far.

In the mean time I realised that a simple PLC might be more appropriate
for the task. But the small ones (Siemens LOGO, Crouzet Millenium) are
mostly very limited in analog outputs and require extra modules to
support a webserver.

Then I found this one: http://www.tri-plc.com/fmd88-10.htm
looks like it has all I require and the price is also not bad, $ 229,- on
the US webshop. I will call a nearby distributor in the morning to check
availability, usability and price overhere.

Anyone experience with this one (or with the brand)? Or other suggestions
of similar boards?

Yes, I have one of these board in the garage.
That's why I suggested: http://www.sparkfun.com/products/7830

The fmd88 is very powerful, but ladder logic just does not make sense to me.

Programming C on MPLAB was much easier.

yes, you can load html pages to the on-board serial flash.

Control loops are written in C.

As I said in an earlier post, Ladder logic is just to strange.
