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?

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.

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?

What about BeagleBone? I know it has digital I/O and analog inputs,
but may not have analog outputs, but I expect a PWM is not beyond it.
It's strong suit is the web software. It runs Linux and has lots of
software support and even a wide variety of modules. You may need to
cobble together something to make the I/O voltages compatible with
your needs, it is a CPU with no special I/O hardware. It's also very
inexpensive at $89, IIRC.

a few tests we reverted to asm. Since those days we have not used PIC in
many projects, the AVR and ARM where in our opinion much easier to work
with.
Have things improved a lot since then? I should think so.
Maybe we should have another go at PIC when we have a suitable project.
How is the compiler these days? When we tried it, I think microchip was
the only one selling a compiler. And at a price I can not justify for
this 3-piece project when I can buy ready hardware+software for just
a little bit more per board.

Dunno about the analog, but WinSystems may have a product that gets close - and maybe romdos with Sockets or even a linux package would get you close to your software solution.

Also, a PIC18 compiler is free with Microchips IDE.
I have developed 10 PIC18 boards in the past 4 years.
I have only experimented with the PIC18 w/ethernet, but I will be added
yet another product to the mix soon.
Microchip products have come a long way from the PIC16C series of 10+
years ago.
If you have time enough to learn ladder logic, you will be able to
pickup PIC18 very easily.

compiler; that compiler was actually very bizarre, but they got working
results. Since then SourceBoost have gone on to make a real C compiler.
Price was a strong concern at that site, so they're still using SourceBoost.
ISTR the only obvious discrepancy from the standard was that sizeof was
treated as a function rather than an operator, so () were mandatory.

Just skip PIC16 and PIC18. PIC24 is OK. PIC32 is better. PIC32 C is GCC based, no porting problem. PICKIT 3 will program any PIC32 chip. TCP/IP stack is available from Microchip library.

The new PIC32MX250F128 seems cool. It is smaller (44 pins vs. 64 pins) and with remapped I/Os (similar to PIC24). The remapped I/Os are missing in previous generations of PIC32. We will be switching to this chip in a new design.

Thank you all for your input. Most of the suggested boards require too

much work on the software and I/O interfaceing for such a low volume
project. I have stored the options for when the volume of this, or
another, project exceeds the expectations.
We have decided to go with the fdm88, which I stumbled upon during this
search. The most obvious downside right now is the ladder programming.
But this is such a small control program that I think I can manage. And
if not, we have people in the company who are much more familiar with
ladder programming who can help or just do the 'entire' software.
