IP Arduino or Industrial PC

[Drunkard #1]

I need to take a serial signal (just a number from 1 - 999), compare it to a list of "active" numbers, and trigger a dry contact if the number is in the "active" list.

I want to date- & time-stamp, and log everything, even signals not on the "active" number list.

I need to be able to alter this list over a simple web interface. Basically a list of clickable numbers, red for active, black for inactive (click number to change status), and a button to dump the log file onto the PC. Obviously some error detection and correction is needed, or maybe just encryption.

What do you guys think is best from an ease of programming point of view, and a reliability point of view. I think the IP Arduino is cheaper and easier (but I haven't got enough experience to be certain), but the Industrial PC might be more reliable and better with the web interface. Also 15x the cost of an IP Arduino.

Thanks.

PM me... I do this stuff for a living. I also have contactable references.
There are better options than the Arduino (which is an amateur's toy) or an industrial PC (overkill).
The chances are good I might have an existing platform I can leverage with some code to do this for you.

Depending on uptime requirements/how critical the device is, I'd personally lean towards a Raspberry Pi. More grunt and resources than an Arduino and inexpensive as well.

Thanks for the suggestions. I just called the usual suspects, and Centurion is actually releasing something that may work at IFSEC, so I'll wait and see. It's easier to find support for over the counter than bespoke.
